V43 Pressure Actuated Water Regulating Valve
The V43 Pressure Actuated Water Regulating Valves
are designed to regulate water flow for water-cooled
refrigeration condensers requiring a large flow capacity
(100 to 1000 gallons per minute). These pilot operated
valves open on pressure increase and provide
modulating operation.
