Product Summary

Large diameter gate valve is a kind of a gate valve, also known as a sluice valve, which is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restric-tion is desired. The gate faces can form a wedge shape or they can be parallel. Typical gate valves should never be used for regulating flow, unless they are specifically designed for that purpose. Large diameter gate valves are characterized as having either a rising or a nourishing stem. Rising stems provide a visual indication of valve position because the stem is attached to the gate such that the gate and stem rise and lower together as the valve is operated. Nourishing stem valves may have a pointer threaded onto the upper end of the stem to indicate valve position, since the gate travels up or down the stem on the threads without raising or lowering the stem. Nourishing stems are used underground or where vertical space is limited. The construction of a large diameter gate valve is quite simple. They generally have two threaded connectors that hook into the pipe system. It is possible for a gate connector to have more than two connections, but this is very rare. A post, called a bonnet, rises above the connectors; this area holds the stopping wedge and the mechanism for raising and lowering it. Lastly, a handle, which controls the rising and lowering of the stopper, sits on top of the bonnet.
