The pressure control valve (pressure control valve) is a general term for the pressure control valve. We have referred to in the usual pressure control valve for pressure control valve. The pressure control valve is also sometimes referred to as pressure valve, mainly is used to meet the requirements of the executive body of the force or torque requirements. Including safety valve, relief valve, pressure relief valve and sequence valve.

The pressure control valve is a general term for the system pressure valve. Below for everyone, for example: solenoid valve is used to control the fluid automation infrastructure components, belonging to the actuator; not limited to hydraulic, pneumatic used to control the hydraulic flow direction, the mechanical device factory is generally controlled by the hydraulic cylinder, so it can be used in the electromagnetic valve.

working principle

Solenoid valve in the closed cavity, in different locations to open a hole, each hole leads to different pipe, the middle cavity valve, both sides are two electromagnets, which faces the magnet coil through electric valve will be attracted to which side, through the control valve moves to file or expose different oil drain hole, and an oil inlet hole Shichang open, hydraulic oil will enter different discharge pipe, and then through the oil pressure to push oil cylinder piston, the piston and piston rod, the piston rod drives the movement of a mechanical device. This current by controlling the electromagnet to control the mechanical movement.


Direct acting solenoid valve:

Principle: when the power is on, the electromagnetic force of the electromagnetic force to shut off the valve seat, the valve open; power, the electromagnetic force disappears, the spring to close the pressure on the seat, the valve closed.

Features: in a vacuum, negative pressure, zero pressure can work normally, but generally not more than 25mm.

Distributed direct acting solenoid valve:

Principle: it is a direct action and the principle of combining the pilot, when the inlet and outlet pressure difference, the power, the electromagnetic force directly to the pilot valve and main valve closed in order to lift the valve, the valve opens. When the entrances and exits to start pressure, the electricity, the electromagnetic force pilot a small valve, main valve cavity pressure increased, the chamber pressure drops, thus the use of pressure to push up the main valve; power, the pilot valve by the spring force or medium pressure to promote the closure of parts, moving down, so that the valve is closed.

Features: in the zero pressure or vacuum, high pressure can also be a * action, but the power is larger, the requirements must be installed horizontally.

Pilot type solenoid valve:

Principle: power, the electromagnetic force to open the pilot hole, the chamber pressure to drop rapidly, in close formed around the low high pressure, fluid pressure to promote the closure of parts moving up, the valve open; power, the spring force the pilot hole closed, the inlet pressure through the bypass hole quickly the chamber around the valve off on the formation of low on the high pressure, fluid pressure to promote the closure of parts moving down, close the valve.

Features: maximum high pressure fluid can be installed (custom) but must meet the conditions of fluid pressure.


1, corrosive media: the king should use plastic and stainless steel solenoid valve; for highly corrosive media must use isolation diaphragm. CD-F. Z3CF. Neutral medium, it should use copper alloy electromagnetic valve, shell material for the valve or the valve shell desquamation often rust, especially the action does not frequent occasions. Ammonia valve can not be used with copper.

2, explosive environment: to choose the appropriate level of explosion-proof products, open-air installation or dust should be used more occasions, waterproof, dust-proof varieties.

3, solenoid valve nominal pressure should exceed the maximum working pressure tube.
