VP526 Three-Way High Pressure Water Valve

Three-way pneumatic mixing valve provides proportional control of hot and/or cold water in unit air conditioners and fan coil systems. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.

• Small size permits installation where space is limited.

• Direct-acting, rolling diaphragm actuator with integral high temperature plastic air connector for 1/4 in. (6-mm) O.D. plastic tubing.

• Spring loaded, self-adjusting Buna-N “V”-ring packing replaceable.

• Brass seats (integral lower, removable upper) and contoured plug provide metal-to-metal seating.

• Stainless steel stem.

• Linear and constant total flow throughout full plug travel.
