Valves

1. Gate valve

Gate valve is a gate with opening and closing parts. The movement direction of gate is perpendicular to the direction of fluid. Gate valve can only be fully opened and closed, and can not be adjusted and throttled. Gate valves are sealed by contact between the valve seat and gate plate. Metal materials are usually overlaid on the sealing surface to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. There are rigid gate and elastic gate. According to the difference of gate, gate valves are divided into rigid gate and elastic gate.

4. Check Valve

Single-flow valves are widely used in high-pressure pipelines. They are mainly used to control the one-way flow of medium in pipelines. As a safety device in pipelines, they prevent the fluid from flowing back into the pump body, thereby protecting the safety of pipelines. Single-flow valves include upper cover type single-flow valves, linear baffle type single-flow valves and dart type single-flow valves. The upper cover type single-flow valve and the linear baffle type single-flow valve are fully encapsulated, which improves the service life of the product and is mainly used in the liquid medium environment. The dart type single flow valve realizes double sealing cooperation between the metal of stainless steel and the sealing ring, which is mainly used for gas environment sealing.

4.1 Swing Check Valve

Swing check valve is in inner rocker arm swing structure. All switch parts are installed in valve cavity without getting through valve body. Except for the middle flange which is equipped with gasket seal and seal ring, there is no other outside dots. Leakage outside the valve is forbidden. Swing type check valve rocker arm and valve disc are connected with spherical surface, which make valve disc possess a certain degree of freedom at 360 degree with a proper position compensation. When swing check valve is fully open, fluid pressure is almost unimpeded. The pressure through valve is relatively small.

It is suitable for clean medium; therefore, medium containing solid particles and larger viscosity shall not be applied. The valve disc of swing check valve is in rotating movement around axis of rotation. Its flow resistance is usually less than that of lift check valve, which is suitable for large bore application.

Technical Data

Technical Data

5. Ball Valve and Plug Valve

5.1 Float Ball Valve

The ball of floating ball valve is floating. Under the effect of medium pressure, the ball can produce a certain displacement and press tightly the seal surface of the outlet end to guarantee the outlet end seal. Seal surface and ball surface are always closed, therefore, the valve is difficult to be eroded by medium. And it is easy to operate and repair, which is applicable to water, solvent, sour and natural gas. Additionally, it can be applied to medium where working condition is poor, such as oxygen, hydrogen peroxide, methane and ethylene. It is widely applied to various industry. Floating ball valve structure is generally applied to moderate and low pressure ball valve.

Technical Data

Trunnion mounted ball valve is applicable to long distance pipeline and general industry pipeline. Its strength, safety and harsh environment resistance shall be taken into special consideration, therefore, it can be applied to corrosive and non-corrosive medium. When operation, the acting force produced by valve front end fluid on ball can fully pass to bearing without moving ball, and the ball will not move to valve seat, in this way, valve seat will not bear greater pressure; therefore, trunnion mounted ball valve is characterized as low torque, small valve seat deformation, stable sealing performance, long-term service life. It is used to high pressure and large bore application. With tight property, advanced spring pre-valve assembly can realize upstream seal. Every valve is equipped with two valves and sealed from per direction; therefore, there is no flow direction limitation for installation and it can be bi-directional application. This valve is usually installed horizontally.
