In a system with irregular changes in high temperature, the gate valve will leak due to the load in the valve end pipe.

Gate valves can be divided into two main types: parallel and wedge. The parallel gate valve uses a flat gate between two parallel valve seats. The popular type is a knife gate valve with sharp edges on the bottom of the gate.

The sealing ring adopts seatback type, mortise type or directly vulcanized on the valve body. The sealing surface of the valve seat flange adopts an O-ring to cooperate with the pipe flange cone, and the sealing effect is good. It is easy to disassemble a

Gate valves are widely used in all types of applications, suitable for above-ground and underground installations. Especially for underground installations, it is important to choose the correct type of valve to avoid high replacement costs.

Generally, gate valves are used to completely close the fluid flow in the pipeline, or to provide the full flow in the pipeline when fully opened. Therefore, it can be used in a fully closed or fully open position.

The valve body is made of 304 stainless steel, which is rust-proof and has a long service life. The ball valve is durable, performs well after many cycles, and is reliable, and can be safely closed even after long periods of non-use.

Resilient seat gate valves are used for purification and pumping of sewage, fire fighting systems, irrigation, industrial pipelines, etc. It has minimal head loss, 100% water tightness and full bore.

Ball valves are more effective in forming tight seals and have higher reliability and life than gate valves, but they are more expensive. They are often used to shut down and control applications. Because the ball valve can be opened and closed instantane

Excellent double-sided sealing function, test zero leakage. Excellent double-sided sealing function, test zero leakage. Simple structure, small size, light weight, fast opening and closing, and fixed operation. Suitable for various medium working conditio

When the handle wheel is turned clockwise, steam and steam move down through the fluid flow, and the gate is squeezed between the two valve seats, so that no fluid leakage occurs when the valve is completely closed.

Do not use the valve as a crowbar to open the flange, as this may cause damage to the flange area and/or damage to the O-ring seal.

Electric actuator ball valves have full-diameter models, some are cavity-filled, and some are V-shaped ball valves. Designed for throttling or switching applications in a variety of industries, including pulp and paper, chemical, power, oil and gas, and m

If the flow, volume and pressure can be adjusted frequently, the stop valve can be used as a control valve. The design of the shut-off valve makes it very suitable for flow regulation and start and stop flow.

This kind of gate valve is more flexible, because its gate can move up or down, there is no obstacle to the flow of fluid or gas, thus ensuring less friction.
