Pressure valve works, advantages and classification

Pressure valve working principle , advantages and classification , high pressure valve ball works can be done 90c rotating action , cocks are generally a sphere , a circular channel or through-hole through the axis . The role of high-pressure valve is used for distribution, cutting and alter the flow of medium body , as long as it is a very small turning 90c and rotational torque can closely to prevent the flow of fluid . Very suitable for  Instrument manifolds  valve switch , shut-off valve , up to now , has been designed to have a ball valve to control the flow and throttling tools , say V-ball . Pressure valve itself has a simple structure, reliable sealing , compact, spherical , and the characteristics of the sealing surface often in the closed state, while it also has strong corrosion resistance ,  Instrument valve manifolds  and operation, suitable for most liquids , gases and the solid medium , etc. , but also in the poor working conditions of media used , for example carbon monoxide, oxygen , and hydrogen peroxide . It is among the many industries have been widely used. High pressure ball valve can not only overall , but also can be modular. Classification by high-pressure valve metal valve body lining classification : as fluorine pressure valves, high pressure valves porcelain , rubber lined pressure valves, high pressure lined valves, metal body lining lining lining pressure valves, high pressure valves and other lead-lined .
