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 MEG is the Model M Series Gate Valve utilizing the Expanding Gate (Hence-EG). The Expanding Gate is a mechanical open and close wedge gate action, closing the gate against the seat on the upstream and downstream achieving a seal on both upstream and downstream seat. This is advantageous then trying to accomplish a positive seal under low pressure and high pressure situations. This Model is considered a directional valve since the segment (Minor) side of the two pieces expanding wedge gate faces the upstream side and the gate (Major) with the threaded neck and stem interface the downstream side.

For low temperature applications, we use PLUSCO 511 AG valve lubricant. It is black in appearance and has a service temperature range of -65°F to 270°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.
