Hydraulic valve is used to reduce and stabilize the hydraulic pressure of a certain branch in the system, often used in clamping, controlling, lubrication and so on. Hydraulic diaphragm metering pump manufacturer to tell you is a widely used hydraulic valve, is an important part of hydraulic valve, the type of moving into straight-pilot, superposition, so what's the classification purpose hydraulic valve?

Hydraulic valve is a kind of operation automation components with pressure oil, it is with pressure oil pressure valve control, usually with electromagnetic valve combination, can be used for remote control of hydropower station, oil, gas, water piping system on and off.

For use:

1. Directional control valve: such as one-way valve, reversing valve, etc. Used to control flow direction of flow.

2. Pressure control valve: such as overflow valve, pressure reducing valve, sequence valve, pressure relay, etc. To control the pressure of the system or to control the oil circuit by the size of pressure.

3. Flow control valve: such as throttle valve, speed-regulating valve, etc. To control the flow of oil in the system.

According to the operation mode: manual, motorized, electrodynamic, hydraulic and electro-hydraulic.

According to the installation method: tubular, plate, flange, superposition, plug-in.

Hydraulic pressure is one of the important parameters in engineering application, and hydraulic components are usually selected according to the pressure of the system. For the convenience of engineering application, in the engineering manual, the hydraulic components are classified according to the pressure.

In China, it is divided into: medium and low pressure series, rated pressure 6.3 Mpa; High voltage series, rated pressure 21Mpa; High voltage series, rated pressure 31.5 Mpa; Ultra high voltage series, rated pressure is greater than 31.5 Mpa.
