SF300X Slow Closing Check Valve

Place of Orign :China
Product name: SF300X Slow Closing Check Valve

Principle:
After the pump stops, the medium flows reversely, the pressure of the valve upper cavity is bigger than that of the lower cavity to have the disc fall off and closed. while the speed controlling the back-water to enter the diaphragm can adjust the speed for the valve to be closed so as to get to the slow closing effect.
Characteristics:
Able to prevent water hammer and water attack from occurring, getting to the slow closing and silencing effect. As a check valve capable of adjusting and controlling the open-close speed, it can make a best open or close speed on the site,when pump is started or stopped.
Application:
Used for the pump outlet of high buildings or other water supply systems to prevent the medium from back-flow and reduce water hammers so as to get a safe and peaceful effect.
e,when pump is started or stopped.
