Automatic valves

Diaphragm type floating ball remote control valve

We can supply a range of automatic control valves such as the above diaphragm type floating ball remote control valve. This is a hydraulically operated valve. It is installed at the inlet of pool or water tower. When the set water level is reached, the main valve, controlled by the pilot valve, closes and stops supplying water. When the water level drops, the main valve controlled by the pilot valve, opens and supplies water to the pool.

This diaphragm-type pump control valve is installed on the outlet side of pump. It serves to prevent backward flow and water-hammer where any type of water head and water backflow is involved. The valve serves as a motorized valve, non-reture valve and water-hammer eliminator and can improve the safety in the system. The valve has a slow-open, quick close and slow-close function to prevent water-hammer when starting or stopping a pump. Only switch on the pump and the valve can will run according to the pump's operation procedure with large flow and little pressure loss.

Typical inch and mm valve internal diameter

The pressure range of valves is typically from Class 150 to Class 1500. A class 150 valve can handle a pressure of 150 psig.
