Article How It Works: Gate Valves
Stop, allow, or throttle the flow of process fluid with very low friction loss.
The M-HT gate valve—with our WKM Pow-R-Seal double expanding gate design, nonrising stem, and metal-to-metal sealing technology—is ideal for temperatures up to 650 degF [343 degC]. The M-HT gate valve has a special high-temperature stem packing that is rated for steam service, follows our stringent quality specifications, and provides dependable service in applications with pressures between 2,000 and 5,000 psi. It is available in sizes from 2 1/16 to 4 1/16 in, with either flanged or threaded ends and in trims for all types of oilfield service.
