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.
