SR SL ST

Solenoid Actuators

Automatic solenoid actuators for control valves fast/slow opening fast/slow closing

Solenoid actuators operate VF, VFR and VFH butterfly valves.

When the coil is unenergized, the inner spring pushes down the plunger and uses gear mating to shift the connected valve to the minimum opening position. When energized, the coil moves the plunger up quickly (SR) or slowly (SL-ST), shifting the valve to the maximum opening position.  

This device, connected to VF, VFR and VFH butterfly valves, is used in two-stage control of gas and air in combustion processes.
