Characteristics and working principle of slow closing check valve of Fushan valve

characteristic:

1. With a check valve with empty opening and closing speeds, it can be adjusted to the optimal opening or closing speed on site when starting or stopping the pump operation.

2. It can be used in high-rise buildings to reduce the occurrence of water hammer and achieve the effect of quiet opening and closing.

3. FS300X valves are recommended for horizontal installation.

4. Pressure rating: PN10, PN16

working principle:

Through pressure transmission, the main valve can be adjusted according to changes in the pilot valve with a small size.

Slow closing check valve:

By setting the flow rate, when the water pump operates, the main valve slowly opens. When the water pump stops running, the pressure drops, the pilot valve opens and closes, and the main valve opens and closes accordingly
