JIS Cast Steel Gate Valve
Gate valve, 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 restriction is asked.
Gate valves are characterized as having either a rising or a non-rising 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.
Non-rising stem valves may have a pointer threaded onto the upper end of the stem to indicate valve position. Non-rising stems are used underground or where vertical space is limited.
