Stainless Steel Vertical Check Valve Introduction:

H42W stainless steel vertical check valve is normally closed, due to the pipeline inlet medium pressure, and overcome the spring resistance to open the valve. When the inlet side of the medium pressure is lower than the outlet end, the spring will push the spool to the valve seat to close the valve to prevent the media countercurrent, it played the role of check. The valve due to the use of spring support spool, so the use of vertical or horizontal installation can be installed.

Stainless Steel Vertical Check Valve Application:
HC42X, HC42T, HC42H PN10 ~ PN25 muffler check valve is suitable for water supply, drainage, fire fighting and HVAC systems. It can be installed at the outlet of the water pump to prevent media backflow and water hammer damage to the pump.

Stainless Steel Vertical Check Valve Advantage：
HC42X, HC42T, HC42H type PN10 ~ PN25 muffler check valve internal flow channel streamlined design, minimal pressure loss, valve opening and closing stroke is very short, stop the pump can quickly shut down to prevent the huge water hammer sound, the formation of mute effect.
