Virtually every hydraulic system requires some type of valve. Valves may control pressure, flow to an actuator, or quantity of flow permitted past a given point. Trends in the valve industry today include miniaturization of traditional designs and space-saving stackable valves. Compatibility with electronic controls means enhanced valve performance.
Innovations include turning to plastics to cut weight while improving lubrication and corrosion resistance. Advanced ceramics are now being used for longer life and contamination resistance. |

Types of Hydraulic Valves
Hydraulic valves can range from simple shutoff valves to precision control valves.
There are many types of hydraulic valves, this list being the most common:
- Angle valves - Manually operated valve with outlet opening at an angle for regulating the flow of a fluid in a pipe
- Ball valves - offer reliable control and allow for tight shut-off
- Block and bleed valves – a small port is used to depressurize the space between the inlet and outlet
- Check valves - for prevention of flow reversal
- Control valves - modify fluid flow
- Directional valves – allows flow through selected passages
- Drain valves - used to drain excess fluid from a system or container
- Needle valves – have a thin tapered needle-like point at the end of a valve stem
- Poppet valves - open and close ports with a sealing device that includes a disk, cone, or sphere has a hole and a tapered disk or cone shape plug on the end of a shaft for guiding the plug portion
- Pressure relief valves - remove excess upstream pressure with regulators to maintain constant outlet pressure
- Safety valves - contain a thermal sensing component that opens or closes in response to temperature changes
- Spool valves - are actuated by a rotary spool that slides to cover and uncover ports within the housing
- Shut off valves – used close a line and stop the flow
- Stack mounted – sometimes called modular valves, these can be assembled to create a valve block
We can repair and re-machine most valves and have the ability to design and make any valve required.
