Multi-function hydraulic control valve is the electric valve, check valve and water hammer eliminator in one, according to the control needs to achieve water level, pressure regulation, throttling and other functions of the new valve, effectively improve the safety and reliability of the system, to meet the system process automation control requirements.

The hydraulic ventilation valve is made of the same material as the valve body to form a sealing ring. Its adaptation temperature depends on the material selection of the valve body. It is generally applicable to industrial, metallurgical, environmental protection and other pipelines for ventilation and adjustment of medium flow. It has the functions of diversion, cut-off, adjustment, throttling, check, shunt or overflow and pressure relief.

The pneumatic gate valve is a more complex automatic control instrument, composed of a variety of pneumatic components and valve body. It is mostly used for occasions requiring quick cut-off and opening.

This series of pipe retractors can be widely used in petroleum, chemical industry, food and medicine, textile, papermaking, water and electricity, water supply and drainage and other systems on all corrosive, non-corrosive gas, liquid, semi-fluid, that is, solid particles powder medium pipeline connection.
