STB-G1 Original Flow Control Valve Hydraulic Speed Regulating Valve

Flow control valve using non compensated throttling.
The flow is reduced in only one direction (A to A1) for STU valves and in both
directions for STB valves, turning the wheel with locking screw right or left.
Guarantees excellent mechanical seal with negligible leakage.
It has a galvanised steel body. The check valve tapered poppet is in tempered
and ground steel.

Application

The throttle 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.

Description
Throttle 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.
Throttle valve may be used in parallel with overflow valve, relief valve, sequence valve, throttle valve and speed control valve and so to form non-return overflow valve, non-return relief valve, non-return sequence valve, non-return throttle valve, non-return speed control valve and so on.
