What is the difference between Johnson Controls VG7000 and VG1800 (VG18) series valves?

VG7000 Series are globe valves: they use a linear stem and plug to regulate flow. Globe valves provide very good flow control linearity and are used where close modulation is required. They are available 1/2 to 2 inch, with bronze or stainless steel trim, and pair with VA7800 Series electric actuators. VG1800/VG12 Series are ball valves: they use a rotating ball with a port through it to control flow. Ball valves have much higher Cv flow factors for the same pipe size — less pressure drop at the same flow rate. They are available from 1/2 to 6 inch in threaded, sweat, and ASME Class 150 flanged end connections, and pair with M9000 Series rotary actuators (M9104, M9203, M9208, M9220). Choose globe valves where close modulation and exact flow control matter; choose ball valves where low pressure drop and high flow capacity are priorities or where pipe sizes exceed 2 inches.

What is the difference between spring return and non-spring return Johnson Controls actuators?

Spring return (SR) actuators use an internal spring that drives the valve or damper to a defined fail-safe position (fully open or fully closed) when power is removed. This is essential for freeze protection systems (valve must open on power loss), smoke control dampers (damper must close or open on power loss), and any application where a defined fail position is required by code or engineering design. Non-spring return (NSR) actuators hold their last position when power is removed — they do not have a spring. Used in general modulating control where the fail position does not matter. For Johnson Controls VA7800 Series actuators on VG7000 valves: spring return models are VA7820 (small valves) and VA7840 (large valves); non-spring return are VA7810 and VA7830. For M9000 Series on ball valves and dampers: spring return models include M9203, M9208, and M9220; non-spring return include M9104 and M9300. All can be field configured for on/off, floating, or proportional (0-10V) control via DIP switches.

What is the Johnson Controls TE-6300 temperature sensor and what systems is it compatible with?

The Johnson Controls TE-6300 Series are passive temperature sensing elements using a 1,000 ohm nickel RTD sensing element, designed for building automation and HVAC applications. The nickel RTD provides stable, robust, long-service-life temperature sensing with a predictable resistance-temperature curve. Available in duct insertion (TE-6310, TE-6320), pipe or well mount (TE-6328), strap-on surface mount (TE-6300-603), and outside air temperature configurations (TE-6100). They are fully compatible with the Johnson Controls Metasys building automation system and with any BAS controller, thermostat, or transmitter that accepts a 1,000 ohm nickel RTD input. The TE-6328P-1 (pipe/well mount, 20-foot lead, 1,000 ohm nickel RTD) is one of the most commonly ordered models. Call (901) 458-2000 with your BAS controller model and we will confirm compatibility.

Johnson Controls — the company that invented the thermostat. In 1883, Warren S. Johnson, a professor at the State Normal School in Whitewater, Wisconsin, was frustrated that a janitor had to interrupt class every hour to check temperatures and adjust basement furnace dampers. He spent three years in his private laboratory developing a solution, and in 1883 received his first US patent for the "electric tele-thermoscope" — what became known as the first electric room thermostat. It used a sealed bimetal element and a small mercury reservoir: temperature changes moved the bimetal into and out of the mercury pool to close or open an electrical circuit. In 1885, Johnson partnered with Milwaukee businessman William Plankinton to found the Johnson Electric Service Company in Milwaukee, Wisconsin. He went on to develop the first automatic multi-zone pneumatic temperature control system — a pneumatic thermostat controlling air flow through a nozzle to operate steam or hot water valves. The company became Johnson Service Company in 1902, and grew across the 20th century through acquisitions and expansions in building controls, automotive, and facility management. Major milestones: the 2005 acquisition of York International HVAC equipment; the 2016 merger with Tyco International (fire and security systems); and the August 1, 2025 completion of the sale of its Residential and Light Commercial HVAC business to Bosch for $8.1 billion — making JCI a focused, pure-play commercial building solutions company. Today, Johnson Controls (NYSE: JCI) is headquartered in Cork, Ireland, with operations in over 150 countries and approximately 87,000 employees. Its building automation and HVAC controls — the Metasys BAS platform, VG-series valves, A19 controllers, M9000 actuators, and TE-series sensors — are the industry standard in commercial buildings worldwide.

M9000 / VA7800 Series Electric Valve & Damper Actuators — Spring Return & Non-Spring Return

Johnson Controls electric actuators are used on VG-series control valves and HVAC dampers. Spring Return (SR) actuators fail to a defined position (fully open or fully closed) on power loss — essential for freeze protection loops, smoke control dampers, and any application where a defined fail-safe position is required. Non-Spring Return (NSR) actuators hold their last position on power loss — used for general modulating control where fail-safe position is not required. VA7800 Series: direct-coupled to VG7000 globe valves, 24V, spring return or non-spring return, configurable on/off/floating/proportional via DIP switches. M9104/M9203/M9208 Series: rotary actuators for VG1800 ball valves and dampers. M9220 Series: high-torque spring return for large ball valves and dampers.

Frequently Asked Questions — Johnson Controls HVAC Controls

Common questions from mechanical engineers, building automation technicians, and HVAC contractors about Johnson Controls valves, actuators, sensors, and temperature controllers. Contact us or call (901) 458-2000 with your JCI part number.

What is Johnson Controls and what products does Memphis Control Center stock?

Johnson Controls (NYSE: JCI) is a global leader in commercial building automation, HVAC controls, security, and fire systems, founded in 1885 by Warren S. Johnson in Milwaukee, Wisconsin. Memphis Control Center stocks Johnson Controls commercial HVAC controls including A19 temperature controllers, VG7000 globe valves, VG1800/VG12 ball valves, M9000/VA7800 electric actuators, TE-6300/TE-6000 temperature sensors, P32/P100 pressure switches, pneumatic controls, butterfly valves, CO₂ sensors, and building automation accessories. Note: Johnson Controls completed the sale of its Residential and Light Commercial HVAC business (York, Coleman brands) to Bosch on August 1, 2025. The commercial building automation controls Memphis Control Center stocks are completely unaffected.

What does the Johnson Controls A19 Series temperature controller do?

The A19 Series is a mechanical line-voltage temperature controller using a liquid-filled sensing element and capillary. It actuates SPST or SPDT contacts when the sensed temperature reaches the setpoint. Available in remote bulb, strap-on, direct immersion, coiled bulb space, and averaging configurations. Temperature ranges from -30°F to 550°F depending on model. Auto reset versions return to normal when temperature recovers; manual reset (lockout) versions require a technician to reset the control after an over-temperature event — required for safety and high-limit applications. Contact ratings: 16A SPDT at 120–277 VAC. Most commonly ordered models: A19ADB-26 (40–120°F manual reset), A19ADB-2 (100–240°F manual reset, direct immersion), A19AAC-9 (100–240°F SPDT, 6' capillary).

What is the difference between VG7000 globe valves and VG1800/VG12 ball valves?

VG7000 Series (globe valves) use a linear stem and plug for flow regulation — excellent modulation linearity, available 1/2" to 2", paired with VA7800 actuators. VG1800/VG12 Series (ball valves) use a rotating ball with a bore — much higher Cv (flow capacity) for the same pipe size, lower pressure drop, available 1/2" to 6" in threaded, sweat, and ASME Class 150 flanged connections, paired with M9000 Series rotary actuators. Choose globe valves where precise modulation matters in smaller pipe sizes. Choose ball valves where low pressure drop and high flow capacity are priorities, or for pipe sizes above 2 inches.

What is the difference between spring return and non-spring return actuators?

Spring return (SR) actuators drive the valve or damper to a defined fail-safe position (fully open or fully closed) when power is lost — essential for freeze protection loops, smoke control dampers, and applications where a defined fail position is required by code. Non-spring return (NSR) actuators hold their last position on power loss — used in general modulating control where fail position is unimportant. For VA7800 Series (VG7000 valves): SR = VA7820/VA7840; NSR = VA7810/VA7830. For M9000 Series (ball valves, dampers): SR = M9203, M9208, M9220; NSR = M9104, M9300. All configure for on/off, floating, or proportional (0–10V DC) control via DIP switches.

What systems are Johnson Controls TE-6300 sensors compatible with?

The TE-6300 Series uses a 1,000 Ω nickel RTD sensing element — stable, robust, and long-life. Available in duct insertion, pipe/well mount, strap-on, and outside air configurations. Fully compatible with the Johnson Controls Metasys BAS and any building automation controller, thermostat, or transmitter that accepts a 1,000 Ω nickel RTD input. The TE-6328P-1 (pipe/well mount, 20-foot lead) is one of the most commonly ordered. Call (901) 458-2000 with your controller model to confirm compatibility.

Does Johnson Controls still make HVAC equipment after the Bosch sale?

Johnson Controls completed the sale of its Residential and Light Commercial HVAC business (York, Coleman, and Hitachi joint venture brands) to Bosch on August 1, 2025 for $8.1 billion. Those product lines are now part of Bosch. However, Johnson Controls commercial building automation and HVAC controls are completely unaffected — the VG-series valves, M9000 and VA7800 actuators, A19 temperature controllers, TE-6300 sensors, P32 pressure switches, and Metasys BAS platform remain Johnson Controls products. JCI continues as a public company (NYSE: JCI) focused on commercial building solutions.

How do I read a Johnson Controls valve model number?

For VG7000 globe valves: VG7 = globe series; next digits encode size and Cv; trim letter (E = stainless, T = brass); end connection letter (T = NPT, S = sweat). For VG1800/VG12 ball valves: VG18 = 1800-series ball body; digits encode size and Cv; the + separator divides valve body from actuator (e.g. VG1841CN+923BGA = 1" 3-way ball valve body + 923BGA spring return proportional actuator). The full assembly is ordered as a single part number. Call (901) 458-2000 with your nameplate model number and we will decode it and confirm availability.

What is PENN Controls and how does it relate to Johnson Controls?

PENN Controls is a sub-brand of Johnson Controls. The A19 Series temperature controllers, P70 series pressure controls, P32 differential pressure switches, P100 encapsulated pressure switches, A28 two-stage temperature controls, and A350 electronic controls are all documented and sold under the PENN Controls brand within the Johnson Controls portfolio — you will see both "Johnson Controls" and "PENN Controls" on packaging and technical documentation. If you are searching for a "Penn A19," "Penn P70," or "Penn Controls" part, you are looking for a Johnson Controls product. Memphis Control Center stocks the full A19/PENN Controls line — call (901) 458-2000 with your model number.
