About This Product

Used to prevent water from falling into return pipes in open circuit systems for air conditioning and heating/cooling equipment in high-rise buildings. When the pump stops, the valve body closes immediately to prevent the water level from dropping in the return pipe. No air pockets are created when the pump starts, which prevents noise and vibration. Maintains appropriate pressure inside the pipe while the pump is operating.

■Place of use

・Air conditioning equipment ・Heating and cooling equipment

■Main features

- An NBR disc is used for the valve body. ・It has good responsiveness to pressure changes, and the valve closes quickly when the pump is stopped.
