Class 150 Flanged Outside Stem and Yoke Gate Valve Pipe Size: 3"
Application & Function:
Didtek Cast steel Gate valves are primarily used for stop valves fully opened or fully closed.
They are not normally considered for throttling purposes, but more for slurries, viscous fluids, etc.
Gate valves are characterized by a traveling wedge, which is moved with the operation of the stem nut.
The wedge travels perpendicular to the direction of the flow.
Gate valves usually have a minimum pressure drop when fully open, provide tight shut-off when fully closed, and remain relatively free of contamination buildup.
Accessories:
Accessories such as gear operators, actuators, bypasses, locking devices, chain wheels, extended stems
and bonnets for cryogenic service and many others are available to meet the customer's requirements.
