Gate valve - Wikipedia

A gate valve, also known as a sluice valve, is a valve which 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 desired.

Rising vs Non rising stem - Valve engineering - Eng-Tips

eng-tips› …› Activities› Valve engineering ForumBe also reminded that knife-gate valves normally have the knives rising to free air (past body/knife sealings) on a non-rising stem. Also: some fluids (gas, steam, toxic, surrounding harming) will require all parts closed in, and a nonrising stem and closed bonnet is required.Normally rising vs non-rising stem only applies to Gate Valves. Non Rising stem Gate Valves are normally cheaper than the Rising stem versions. Why are you asking this question? What is your potential use (purpose for this valve)? Sometimes its possible to do all the right things and still get bad resultsRising stem is normally with Outside Screw & Yoke with the stem threads being isolated from the medium by stem packing whilst in non rising the thread is exposed to the medium therefore could be subject to erosion, corrosion etc depending on the medium therefore should be of more corrosion resistant material hence more expensive. The only advantage I can think of with non rising stem is where space is limited and both non-rising and rising can apply also to globe valves as well as gate. On a recent project our contractor stipulated rising stem as per data sheets but vendor offered non rising in small bore globe valves which was accepted as stem material was suitable for the medium.Often this is no more than custom and practice, not technical. Many operators prefer rising stem as it is much easier to rapidly see from a long way away which valves are open or closed. On a big manifold or complex pipe system this can be very important. Rising stems are exposed to the elements and can become corroded, painted and require greasing on a regular basis. Remember - More details = better answers Also: If you get a response it's polite to respond to it.1Be also reminded that knife-gate valves normally have the knives rising to free air (past body/knife sealings) on a non-rising stem. Also: some fluids (gas, steam, toxic, surrounding harming) will require all parts closed in, and a nonrising stem and closed bonnet is required. In general, for harmless fluids, I agree with all above: it is mostly a practical and pricing question, if quality and lifetime els is about equal.
