First, water sealing effect, big pressure. With a smaller float control, able to withstand greater pressure of the liquid. The traditional straight-sealing general pressure less then 0.6MPA, the product pressure less then 1.0MPA.
Second, water flow, and high efficiency. Water faster than the traditional straight-sealed, less splash.
Third, easy installation, flexible adjustment. Can be installed at any angle adjustment. Toxic, tasteless, non-lead salt stabilizer, can be used for drinking water.
Fourth, corrosion resistance, wide adaptability. Widespread use of solar energy in different media containers, cooling towers, environmental protection, anti-corrosion, chemical and other fields, and wide adaptability than traditional metal float valve.

Working principle:
This product is an automatic control of water tanks, water tower liquid level of the hydraulic control valve.
When the water dropped by more than a preset value, the float valve opens, the piston chamber pressure is reduced, the piston down the formation pressure, under pressure in this role in the water supply valve opens;
when the water level rises to a preset height, the float valve sealing, piston chamber pressure is increasing causing the valve closed rest water.
