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, COā 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 -30Ā°F to 550Ā°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 ā required for safety and high-limit applications. Contact ratings: 16A SPDT at 120ā277 VAC. Most commonly ordered models: A19ADB-26 (40ā120Ā°F manual reset), A19ADB-2 (100ā240Ā°F manual reset, direct immersion), A19AAC-9 (100ā240Ā°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 ā excellent modulation linearity, available 1/2" to 2", paired with VA7800 actuators. VG1800/VG12 Series (ball valves) use a rotating ball with a bore ā 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 ā 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 ā 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 (0ā10V DC) control via DIP switches.
What systems are Johnson Controls TE-6300 sensors compatible with?
The TE-6300 Series uses a 1,000 Ī© nickel RTD sensing element ā 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 Ī© 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 ā 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 ā 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 ā call (901) 458-2000 with your model number.
