Resilient seated rising stem gate valve

Resilient seated rising stem gate valve

Resilient seated rising stem gate valve has general resilient seated gate valve's advantages and at the same time can show the valve's opening directly. It can open or close reliably and quickly so is widely used in fire protection and industry system. Generally, the valve is installed in the high position to the ground.

Features of Resilient seated rising stem gate valve can be summarized as:1)Nominal pressure: 1.0-2.5MPa;2)Working temp.:0-120℃;3)Flanged end: GB/T17241.6 GB9113;4)Nominal diameter: 50-400mm;5)Service: water, oils, gas etc.;6Inspection and test: GB 13927 API 598. Gate valves are characterised as having either a rising or a nonrising 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.

Resilient seated rising stem gate valve special for fire protection has resilient seated gate valve's advantages. And it shows the valve's opening directly so it's possible to see the valve's opening in a long distance and take effective actions. It opens or closes reliably and quickly so it is often used in fire protection system. Typical gate valves should never be used for regulating flow, unless they are specifically designed for that purpose. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel.
