STBF-NPT flow control valves

Thanks to STBF-NPTF restrictors it is possible to adjust the oil flow passing through and control the speed of a hydraulic cylinder or motor. The adjustment is bidirectional. The valves do not have an integrated hydraulic compensator and the set flow is effected by the pressure drops accross the valve. The valves can be easly installed inline inside the hydraulic circuit through the two NPTF threads ports. By means on a nut, available on demand, it is possible to panel the setting knob. Depending on the chosen size, the STBF-NPTF valves can be installed inside circuits with max working pressure of 400 bar (5800 PSI) and flow up to 300 lpm (79.2 gpm).
