Hydraulic Flow Control Valve Speed Regulating Valve STB-G3/ 4 One-way Throttle Valve
Description
Bi-Directional flow restrictor hydraulic valve, also called check valve, is used in hydraulic system to control the flow and cutoff of oil.
If the oil inlet and outlet of a straight through check valve are in a axial direction, the valve may be connected directly to the system pipe via threaded pipe fittings.
The opening pressure of check valve may be either 0.04MPa or 0.4MPa. The former is normally used in pressure pipes to prevent oil from flowing in reverse direction, while the latter may be normally used as a back pressure valve.
Application
The flow control valves are able to produce a pressure drop between inlet and outlet. They are not pressure compensated so the regulated flow can change infunction of the pressure and of the viscosity.
