Leading Hydraulic Solenoid Valve Manufacturers

A hydraulic solenoid valve, also known as a solenoid-controlled directional valve, controls liquid flow in hydraulic systems. The valve is controlled by a solenoid, a ferromagnetic core wrapped in an electric coil. The valve is composed of several chambers, or ‘ports’. The solenoid opens and closes the ports, and the spool rotates inside the valve. The spool, a cylindrical component, serves as the valve by preventing or allowing liquid to travel through these ports, depending on where it is located. Read More…

Hydraulic Solenoid Valves Hydraulic valves hold and transfer the flow and pressure of hydraulic fluid in a hydraulic system. The most common genre is the hydraulic control valves, which monitor how much of the liquid flow is going through what chambers at once, ensuring that there is no overflow or leakage.

How Hydraulic Solenoid Valves Function

A solenoid is a wire coiled around a core. The core is made of an armature (a moving core) and a stationary core, both loaded with springs. The armature can move away or toward the stationary core when electrical current flows through the wire. The movement of the armature opens and closes the valves. When de-energized, a closed valve will stay closed, and an open valve will stay open.

Types of Hydraulic Solenoid Valves


In a hydraulic circuit, a two-way valve controls the direction of fluid flow. A two-way closed solenoid valve has two pipe links: a cavity port for the inlet and a body orifice port for the outlet.

Two Way Closed Solenoid Valves

The plunger is down in a usually closed solenoid valve when it is not energized, which seals the valve and stops liquid or gas from passing. When the solenoid is turned on, the magnetic field raises the plunger to open the seal and allow liquid flow.

Two-way Open Solenoid Valves

Media flows into the inlet port and out the stop port when the device is naturally de-energized. When the valve is activated, the plunger seals the aperture and prevents flow. When the orifice opens, the valve's flow resumes.

Three Way Solenoid Valves

A 3-way solenoid valve comprises three pipe connections: the stop port, the body orifice port, and the cavity port. The body orifice and the stop orifice, one of which is always open, enable two flow pathways.

3-Way Open Solenoid Valve

In a 3-way open solenoid valve, the plunger is raised when the power is turned off. This seals the stop orifice and permits flow from the body orifice port and out the cavity port. When the power is on, the body orifice is sealed, and fluid flows from the cavity out the stop port.

3-Way Normally Closed

In a 3-way closed solenoid valve, fluid flows through the cavity port and out the stop port while the plunger closes the body orifice. When the coil is turned on, the plunger rises to block the stop orifice and allow flow from the body orifice port out the stop port.

3-Way Directional Control

3-way directional control means the plunger can be raised or lowered when the valve is on. Raising the plunger seals the stop orifice and opens the body orifice. Lowering the plunger seals the body orifice and opens the stop orifice.

Four-Way Solenoid Valve

In a four-way solenoid valve system, five valves change the flow direction. While resting, the core spring forces the solenoid forward against the base. The core's function is to seal it because when the solenoid is activated, it opens. The coil pulls the core away from the pilot base when electrified, allowing fluid to enter the pilot itself. As long as the coil is turned on, the pilot is forced against the spool to change the flow.
