- No leakage when closed thanks to the single-seat valve and plug.
- The large diaphragm provides a reliable response to pressure fluctuations and shut-off.
- When used as a pump drain valve, the valve relieves excess pressure due to fluctuations in the load and maintains a constant pressure in the pipeline while the pump is running.
- It is used to maintain the water pressure in the pipeline when the pump is turned off in an open circuit in buildings of large and medium height.
- The interior and exterior surfaces of the GD-20RC are nylon 11 coated for superior corrosion resistance.
