The pump control valve consists of a main valve, solenoid pilot valve, needle valve, ball valve, check valve, travel switch, micro-filter and pressure meter to form a hydraulic control receiver system. When the pump needs to stop working, the pump stops running after 90% of the main valve is closed by the inlet pressure first. The remaining 10% is closed by the return water. To avoid water hammer phenomenon. Water pump control valve using electromagnetic pilot valve control, without other devices and energy. Save energy, easy maintenance, stop the pump smoothly. The solenoid valve can be used with AC 220V or DC 24V, which is mainly used in building, living area and other water supply pipe network system and urban water supply project.

Hydraulic water level control valve, when the water level in the pool or water tower falls, the float valve is opened to drain, the inlet pipe with pressure water will be the valve piston to hold up, the sealing surface is open, the valve that is open to the water supply, when the water level rises to the control valve, the float valve is closed, the piston moves down to the sealing surface is closed, the valve that is to stop the water supply. Therefore, it is suitable for industrial and mining enterprises, civil buildings in a variety of water tanks (pools), water tower automatic water supply system. Can also be used as atmospheric boiler circulating water supply control valve.

Self-pressure regulating valve without additional energy, the use of the regulated medium's own energy as a power source introduced into the actuator to control the spool position, change the pressure difference between the two ends and the flow rate, so that the valve or the valve pressure stabilization. Self-pressure adjustment valve has the advantages of sensitive action, good sealing, pressure set point wave power is small, widely used in gases, liquids and media pressure stabilization or pressure relief stabilization of automatic control.
