Hydraulic valves
Principle work of hydraulic valves
Hydraulic valves are hydraulic devices which control the parameters of the fluid flow by changing the flow area of the hydraulic device through the movement of the shut-off-control element under the influence of the fluid flow (directly or indirectly)
Hydraulic valves types:
- check;
- relief;
- reduction;
- brake valves;
- discharge valves;
- chokes;
- hydraulic locks.
This type of valves are either control valves (regulate the pressure in the fluid flow) or directional valves (stop or let the fluid flow when the flow parameters specified by the valve settings are reached).
Hydraulic valves application
Hydraulic valves are used in case of necessary of the adjustment of the fluid passing through the pipeline. Control valves, for example, are used to adjust fluid pressure. Directional valves allow or block the flow, when it reaches specific parameters of pressure, temperature, speed.
The entire range of hydraulic valves and other hydraulic equipment is presented on our website. You can also choose the necessary hydraulic valves by type of installation: cartridge, modular, tiled (butt), pipe and flange mounting.
