FM4 7 1/16" 3-5M, Ball Screw, Slab Gate Valve

All Model M Series Gate Valves are profiled after the original WKM Model M Gate Valve. All dimensions interchange parts. The Model M Series Gate Valve utilizes a "Packing Injection Fitting" in the bonnet assembly to provide an injectionable stem packing to the stem seal area while under pressure. The Model M Series Gate Valve is a cast body line.

The Model MSG (Slab Gate-Hence Model SG) is dimensionally the same as the Model M, except utilizes the slab gate which is preferred for manifold and frac applications. The Slab Gate is a bidirectional gate valve sealing on the downstream gate to seat when placed in the flow stream facing either direction. The Slab Gate requires pressure from upstream to force the seal of the gate against the downstream seat.

This Model MSG (Slab Gate) BS (Ball Screw) is designed for the 7 1/16" 5000 WP gate valve to reduce the number of turns required by ½ and the operating torque by ½ as compared to the handwheel operation. This Model utilizes a lower bonnet and balance stem. The Ball Screw is the same Heavy Duty USA made Ball Screw used in the Valveworks 10M and 15M Gate Valves.

For low temperature applications, we use Valveworks USA proprietary valve lubricant (SAM 4012B). It is black in appearance and has a service temperature range of -75°F to 250°F.

All dimensions in inches, weights in lbs. If dimensions/weights are critical, please consult factory. Valveworks USA reserves the right to alter designs and specifications without notice.
