Structural characteristics of VICKERS directional control valve

Structural characteristics of VICKERS directional control valve

Used to control the start, stop, and direction of oil flow. VICKERS has two control types: hydraulic pilot pressure type (dg3v-5 type) and built-in electromagnetic pilot valve (dg5v-5 type).

Including spring bias, spring pair, and belt position type.

Firstly, the sensing pressure and oil leakage can be independently configured for internal or external connections.

All types of valve cores are designed to provide good small impact, fast response characteristics, control of the main valve, and improved liquid control damping plate options that can increase the speed of core movement.

Function: Used to control the start, stop, and direction of oil flow

Control types: including hydraulic pilot pressure type (dg3v-5 type) and built-in electromagnetic pilot valve (dg5v-5 type)

Structural features: including spring bias, spring pair, and belt position types, sensing pressure and oil leakage can be independently configured for internal or external connections

Performance advantage: Designed to provide good small impact and fast response characteristics, the liquid controlled damping plate option for controlling the core movement speed of the main valve has been improved

Working principle: A hydraulic control valve that can make the pressure of the output oil change proportionally with the input electrical signal (current or voltage)

Control mode: The electromagnet directly generates thrust on the valve core, and the input voltage can vary between 0-24 volts, generating continuously changing hydraulic pressure

Application Function:

Constant pressure overflow: maintaining a constant pump outlet pressure in a quantitative pump throttling control system

Security protection: Open overflow for overload protection when the system is overloaded

Other uses: Can be used as an unloading valve, remote pressure regulating valve, high and low pressure multi-stage control valve, sequence valve, generating back pressure, etc

Suitable medium for Vickers solenoid valve:
1. Choose different types of solenoid valves for gas-liquid or mixed states.
2. Products with different specifications and medium temperatures may cause the coil to burn out and the seals to age, seriously affecting their lifespan. The medium temperature should be selected within the allowable range of the solenoid valve.
3. The viscosity of the medium is usually below 50cSt. If it exceeds this value, a high viscosity solenoid valve with a diameter less than 15mm should be ordered.
4. When the cleanliness of the medium is not high, a backwash filter valve should be installed in front of the solenoid valve. If the medium flows in a directional manner and backflow is not allowed.
