Isolation duty
Use a gate valve where the normal operating position is fully open or fully closed. For deliberate throttling, start with a globe valve instead.
Forged steel gate valves for full-open or full-closed isolation. Compare ASME and PN pressure systems, threaded, weld and flanged ends, body grades and trim.
A gate valve is normally selected for an open or closed position. Define the service conditions first, then choose the pressure system, end connection, construction materials and nominal size.

State design and operating pressure and temperature. The class or PN designation alone does not define the allowable pressure for every material.
Select NPT, socket-weld, butt-weld or a flanged end to suit the piping specification. Confirm end-to-end and mating dimensions before fabrication.
Select the body grade for temperature, corrosion and project requirements. Check stem, wedge and seating materials separately as part of the trim.
Narrow this family by construction, pressure system, rating, end connection, body material and internals.
