Product Description

Adjustable Hydraulic Solenoid Operated Speed Control Valves

The series is pressure trace type using on hydraulic cylinder. Hydraulic motor that needs speed to control situation with pressure compensation so the press change of in an out port do not affect flow and the flow nose of mouth of check valve can be completely deleted.
Then in port pressure can trace loading pressure so can reduce pressure loss to save electric power to prevent the raising of oil temperature.
SF series is made by adjustable flow control valves & Solenoid Control Valve is belong to two section solenoid adjust speed valve. General flow can be controlled when solenoid valve act the fluid can free flow. Application for slow speed, high speed two section speed control situation, suitable for injection machine close mold ciruit, press M/C & lathes M/C.
SDF series is made by adjust Flow Control Valve & solenoid valve belong to single adjust speed valve. General stop fluid solenoid act, the flow can be controlled Application for the M/C is using electric sign to control suitable for injection hydraulic motor circuit, lift M/C.
SFD series is solenoid two section adjust speed valve be used on hydraulic cylinder which need slow speed, high speed, tow section speed situation application for injection M/C close mold circuit, press M/C. lathes M/C
SD series is made by flow valve & solenoid control valve is a solenoid adjust speed valve. Using electric sign to be the switch power of hydraulic circuit
SKF series double solenoid adjust speed valve be used on hydraulic cylinder the speed need slow speed, high speed, instant speed three section control situation. As with double coil so the speed can be used more convenience. Application for injection mold M/C. press M/C. lathes M/C.
