Product Summary

The Pressure Sealed Gate Valve I s a kind of gate valve which also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The obvious 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.

Typical gate valves should never be used for regulating flow, unless they are specifically designed for that purpose. Flow rate does not change evenly with stem travel, because on opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. Typical gate valves are designed to be fully opened or closed. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow.

The advantages of pressure sealed valve are their allowing the structure of the valve body, valve cover tight junction structure; the provincial Public Works save cost, safe and reliable. And valve pressure in the valve cover seal, the use of the modular structure to achieve linear sealed its seals at the same time the use of austenitic stainless steel, anti-cavitation, extended life, thereby ensuring that the valve seal under high-pressure differential did not leak. The valve in the 2500 pounds and above level, the body cavity sealing contact with the surfacing of stainless steel lining Department to avoid the valve sealing region under high-pressure differential erosion by soft drinks appear Ma leakage point, thus to ensure a safety valve, long-term operation.
