What is the Resilient Seated Pipe Gate Valve?

A Resilient Seated Pipe Gate Valve is a type of gate valve that is designed to regulate, isolate, or control the flow of fluids or gases in a pipeline. It is called “resilient seated” because it has a soft elastomeric seat that can adjust and adapt to changes in pressure and temperature, which helps to prevent leakage and ensure a tight seal.

The valve is typically made up of a gate, which is a flat or wedge-shaped disk that slides up and down within the valve body, and an actuator, which is used to open or close the gate. When the valve is in the closed position, the gate is pressed against the seat, creating a tight seal that prevents fluid or gas from flowing through the pipeline. When the valve is in the open position, the gate is lifted away from the seat, allowing fluid or gas to flow through the pipeline.

Resilient seated gate valves are commonly used in a wide range of industries, including water and wastewater treatment, oil and gas, chemical processing, and power generation, among others. They offer a number of advantages over other types of valves, including high durability, low maintenance requirements, and excellent resistance to corrosion and erosion.

Performance characteristics

1)Integral rubber-coated gate: The ductile iron skeleton is covered with high-performance rubber and the latest vulcanization technology inside and outside.
2)One-piece copper nut: The copper nut of the valve stem and the ductile iron bracket are tightly connected as a whole by a special process to ensure that they will not be loosened under long-term operation and avoid the control failure of the valve.
3)Flat and low seat, the bottom of the elastic seat seal gate valve adopts a full flow channel straight-through design, which is equivalent to a straight pipeline, and is not easy to accumulate debris, ensuring reliable sealing and unobstructed fluid flow.
4)Lightweight structure: The compact structure reduces the maximum working height by more than 60mm to 300mm compared with the traditional gate valve, saving engineering space; the body is made of ductile iron material, and the weight is reduced by about 20% to 30% compared with the traditional gate valve, and the installation and maintenance are convenient.
5)Corrosion resistance: The inner and outer surfaces of the valve are painted with epoxy resin powder, and the inner parts are made of stainless steel and copper alloy to prevent rust and fluid corrosion.
6)Four seals are used to completely eliminate the leakage of the valve: the first seal, the upper seal of the valve stem and the valve cover, is sealed with high-quality O-rings; the second seal, the special seal is used between the valve cover and the valve body between the third valve stem and the stuffing box, use high-quality O-rings; the fourth valve stem and packing gland bracket use high-quality O-rings.
7)The valve stem is made of high-quality stainless steel, and the hardness of the valve stem reaches HB200-275 after quenching and tempering treatment, which not only ensures the strength of the valve stem, but also increases the wear resistance of the valve stem.
8)The valve seals in both directions and can be installed anywhere in the pipeline.
9)The manual actuator is a hand wheel, which can be replaced with gear, electric and other actuators.
