Hydraulic Valve

Hydraulic valves help to regulate and coordinate the flow of hydraulic oil through a hydraulic circuit or framework in order to complete specific tasks. The direction of the hydraulic oil flow is controlled by the use of valves that work as switches. Non-return valves are often placed in the system to prevent back flow or pressure. Hydraulic valves can be used to close hydraulic lines, restrict the flow, bypass or send the flow to certain areas.

Hydraulic valves come in a huge range of styles and sizes to suit different applications. They can be controlled automatically or manually through the use of mechanical cables, plungers, levers or torque motors, physically by a system operator or by the use of pneumatic or electrical devices. There are also valves designed to be used in the system and using the pressure contained in the hydraulic circuit to automatically self-activate if or when required.

The manufacture of the hydraulic system will specify the correct pressure rating the system requires, the minimum and maximum operating temperatures the valves will need to withstand and the dimensions required ensuring the system has enough flow along with the valves mounting requirements.

Types of Hydraulic Valves

There are three primary groups of hydraulic valves, but these are divided into many subgroups that are made to meet specific requirements.

• Solenoid Valves
These are usually spool or poppet valves and can be servo or pressure controlled

• Flow Valves
These can be in the form of pressure-compensators or hydroststs or simple needle valves. They are used to meter-out or meter-in the hydraulic oil

• Pressure Control or Relief Valves
These are used to relieve the pressure if it builds up too much and redirect the hydraulic oil back to the oil reservoir

Materials
Hydraulic valves are made of a variety of materials depending on the conditions they’re required to operate in and the flow ratings specified. Materials include carbon steel, brass, stainless and a whole range of synthetics.

Ball valves are one of the simplest and less expensive types of hydraulic valves available. They are usually hand operated and made with a handle that kinks to a ball within the valve. There is a central hole in the ball that when aligned correctly allows for the uninterrupted flow of the hydraulic oil. The ball can be turned so it partially blocks the flow or perpendicular so it completely stops the flow.
