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.
