Hydraulic Solenoid Valve

In the market for a replacement hydraulic solenoid valve? Look no further than Gorilla Spares. We offer unbeatable customer service from order-placing through delivery.

Gorilla Spares is a multi-vendor marketplace that sells replacement hydraulic, electrical, electronic, and robotic parts manufactured specifically for the industrial, agriculture and aerospace industries. We source the highest quality aftermarket parts, including Parker and Eaton replacement valves, from the best companies and offer them to you at excellent prices.

Our vendor-partners are among the best suppliers in the high-quality hydraulic parts business but lack the resources to develop and maintain their own sustainable ecommerce sales platform. We connect them with our clients who have trouble finding their products online or via traditional business-to-business sales and distribution channels.

What are Solenoid Valves?

A solenoid valve is a device used to direct the flow of hydraulic fluid in a system to and from an actuator by shifting a spool or poppet within the valve. It is typically powered by electromagnetic energy in a coil.

The most common solenoid valve is a 2-way valve which has only two ports. They can be 3-, 4-, or even 5-way valves depending on use, and the spool or poppet design makes them well-suited to various functions and applications. All solenoid valves are either direct-acting valves or pilot-operated valves.

Direct Acting Valve

In this valve, a coil magnetically opens the valve in direct action, lifting the shaft and the seat of the valve without depending on outside pressure. These valves only need full power when opening the valve, as they can stay in an open position even when operating on low power.

Pilot-Operated Valve

In this valve, the solenoid activates a smaller “pilot” valve that in turn opens up a larger valve operating at much higher pressure. These valves usually need to maintain full power in order to remain in an open state, and they perform at a slower rate than direct-acting solenoids.

Troubleshooting Solenoid Valve Problems

Here are several common problems that can occur in solenoid valves:

Valves Don’t Open: Solenoid valves may not open because of a power failure, dirt under the diaphragm, wrong voltage, uneven pressure, corrosion, missing components, or a burnt coil.

Valves Partly Close: Sometimes valves fail to close. This is typically the result of a manual override, pressure difference, residual coil power, damaged armature tube, inverted or damaged valve seats, or missing components.

Buzzing or Hammering Sounds: You may hear a loud hammering sound or a buzzing sound every time a valve opens or closes. These noises can be caused by the difference in the inlet or outlet pressure inside the system.

Coil Problems: The coil may be burnt, melted, or stay cold even with power on. These problems can be the result of a short circuit, dragging coil armature, wrong voltage, and high liquid temperatures.
