Description
Honeywell VP526A1019 Three-Way Unitary Mixing Valve, 1/2" NPT, 2.5 Cv, 3–10 psi Spring Range The VP526A1019 is a compact, three-way pneumatic mixing valve designed for proportional control of hot and/or cold water in unit air conditioners, fan coil units, and similar terminal HVAC systems. Engineered for smooth, linear control and dependable performance, this valve is also a direct replacement for many legacy valves from manufacturers like Johnson Controls, Powers, Robertshaw, Barber-Colman, and older Honeywell models. Key Features Compact Size: Ideal for space-constrained installations in OEM or retrofit applications. Durable Construction: Features stainless steel stem and brass seats for long-lasting, metal-to-metal sealing. Linear Flow Characteristic: Maintains consistent total flow throughout full valve stroke for stable control. Pneumatic Actuator: Direct-acting actuator with integral high-temperature plastic air connector for 1/4” (6 mm) O.D. tubing. Serviceable Design: Self-adjusting Buna-N “V”-ring packing is easily replaceable without removing the valve.
