Since the
Gate Valve can be fully opened or closed by turning the handle 90° under normal circumstances, it is easy to achieve rapid opening and closing. It can achieve rapid opening and closing, and the opening and closing time of some structures is only 0.05-0.1s to ensure that it can be used in the automation system of the test bench. When the valve is opened and closed quickly, the operation is impact-free.
At present, the valve seats of most
Universal Valve are made of elastic materials such as polytetrafluoroethylene. The sealing pair composed of metal and non-metallic materials is usually called soft seal. Generally speaking, the sealing of soft seals is easy to ensure, and the processing accuracy and surface roughness of the sealing surface are not very high.
Because polytetrafluoroethylene has good self-lubrication, the friction and wear with the ball are small, and due to the improvement of the ball processing technology, the roughness is reduced, thereby increasing the service life of the Gate Valve.
① The sealing pair of the ball and the valve seat will not be scratched, worn sharply, or stuck during operation (without lubricant), so it can be reliably used in corrosive media and low-boiling liquids;
② The built-in
Valve Stem structure eliminates the hidden danger of the valve stem flying out due to the loosening of the packing gland under the action of fluid pressure;
③ The Gate Valve adopts an anti-static and fire-resistant structure, which is suitable for pipelines transporting oil, natural gas, and coal gas.
