The hydraulic valves body is made of cast iron, cast steel or stainless steel, which is resistant to corrosion and abrasion; The core sealing component adopts special elastic diaphragm, with excellent sealing performance and no leakage; No complex transmission parts in the internal structure, low failure probability and long maintenance period.

The opening and closing process of the Flow control valve is stable, no violent water hammer effect will be generated, and the pipe network and equipment can be effectively protected from impact damage; The matched filter can be installed to prevent impurities from entering the control pipeline and avoid valve blockage.

Routine maintenance only requires regular cleaning of the filter and inspection of the integrity of the float and diaphragm; During commissioning, the liquid level control accuracy can be fine-tuned by adjusting the needle valve, which is simple and requires no professional technicians.
