Pressure Quick Emptying (Relief) Hydraulic Control Valves

Dimensions : DN50-DN200

Connections : PN16

Op. Temp. Range : -30 / +180

Material Structure : GGG40

Applications: on the watering systems, before the pump

The rapid pressure relief control valves are the safety control valves that protect the piping systems by evacuating the excessive pressure fluctuations caused by the opening and closing of the pumps used in the pumping and irrigation networks to the atmosphere.
The valve protects the pipe system and other armatures by quickly evacuating the excess pressure that may occur in the network pressure to the atmosphere.
The valve opens quickly. After finishing the tapping process, it closes slowly and completely tightly without creating a pressure surge in the network again.
The valve works completely hydraulically with line pressure without requiring any extra energy.
Since the valve is designed with diaphragm actuator, its maintenance is very easy and cheap.
The valve works safely in horizontal and vertical installations.
