Hydraulic valve actuator MHW70

linearpiston

The MHW model of Saf-T-Gard actuators provides enough force to shear wireline, braided line, or coiled tubing in the event that the well must be shut down during an emergency condition. It contains the same features as the standard MH model and adds springs that provide the thrust to perform the cutting force required. Saf-T-Gard MHW actuators offer a reliable and robust design that can be installed in harsh and remote environments.
