2020 Update – Following on from last year’s blog on overcentre valves and how they work, we catch up with overcentre valves and refresh ourselves on how they have replaced the counterbalance valve as the go-to solution for load control, with the best results being seen when the valve is mounted directly onto the actuator itself.

What are flow control valves and why do you need them in your hydraulic system? In this week’s blog we examine how flow control valves help to regulate system speed and adjust to variances in pressure and temperature.

Hydraulic systems sometimes have a manual relief valve integrated into the design. This valve relieves built up pressure and is usually deployed when the mechanical system fails at some point and stops the pressure being relieved automatically according to the normal operation of the equipment. Essentially it is a safety feature that does not rely on a mechanical or electronic process but on human interaction which over-rides the system, returning the machinery back to an idle position. In ca...

Valves Set the Course in Hydraulics The directional-control valve is one of the principle components of any hydraulic systems. In this post we look at the different types and how they operate:

Introduction to Control Valves in Hydraulic SystemsIn the world of industrial, mobile and aerospace equipment, hydraulic power systems are very popular. They enjoy a high power-to-weight ratio in addition to being able to be stalled, operated intermittently and even reversed. They can also accelerate fast and are quick to respond. Another attractive feature of the fluid power system is that they can be very long lasting in addition to offer reliable operation rates.Hydraulic systems are able to ...

Troubleshooting Sequence Valves Sequence valves have an important role to play in hydraulic systems. They control flue flow to both the primary and the secondary circuits. They also control the sequence that particular events occur and maintain the pressure of the primary line. It’s important to remember that the pressure of the sequence valve should never be below 200 psi of the system relief valve setting.

What You Need to Know About Hydraulic Valves Hydraulic Check Valve The purpose of check valves within Hydraulic Power Packs and Systems is to allow fluid to pass in one direction but to prevent it from travelling the other direction, or doing what is known as a reverse flow. The device is usually added to a pipe to prevent oil from flowing backwards. When necessary the valve will close so that all backward movement of fluid is stopped.
