Primary Pressure Regulating Valve / Drain Valve, GD-20RC Series

Primary Pressure Regulating Valve / Drain Valve, GD-20RC Series

Used as a pump relief valve, relieving pressure changes caused by load fluctuations and maintaining a constant pressure inside piping during pump operation.

[Features]
· Used to prevent fluids in the tube from draining when a pump stops in an open circuit system used in a medium or high-rise building.
· A large pressure detection unit is provided, ensuring a reliable response and cut-off to pressure changes.
· GD-20RC provides excellent corrosion resistance due to Nylon 11 coating treatment performed on the inside and outside of the main body.
