The working principle of the forged steel ball valve is to open or block the valve by rotating the stem. Usually for the full diameter ball valve, 90 degree Angle switch, light, small size, can be made into large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface is often in the closed state, not easy to be washed by the medium, in various industries to get the most popular application. Forged steel ball valve classification: low pressure forged steel ball valve,

High pressure forged steel ball valve is according to the needs of users, in order to meet the requirements of vulcanization application cracking in the vulcanization environment, this series of high pressure forged steel ball from the design, material selection, manufacturing, testing, surface treatment and painting are strictly in accordance with the American corrosion engineers Association NACE standard requirements. This series ball valve not only selected the best material and the inner material with the same color surface nickel-plated 316 material, the sealing ring is made of the best polymer material. The valve is not only anti-corrosion, anti-vulcanization ability is strong, fire, ***, sealing performance is good, the use of pressure and temperature **, full diameter and diameter reduction complete, and can be equipped with a variety of driving devices, is the chemical industry, petroleum torch refining, natural gas mining and transportation system ideal valve choice. The main function
 
When the stagnant medium in the valve cavity increases pressure abnormally due to temperature change, the medium pressure pushes the valve seat away from the ball to achieve the effect of automatic pressure relief, and the valve seat automatically resets after pressure relief.
In addition to the general sealing of the valve seat, the special sealing structure can play an emergency rescue role when the sealing ring is damaged and the leakage occurs.
When the fire or abnormal temperature causes the seat sealing ring to burn or soften. Valve operation is still reliable, at the same time, the valve seat and the ball form metal to metal, to achieve a temporary sealing effect, prevent the fire further expansion, in line with the provisions of AP16FA.
Unscrew the ejector to check whether there is leakage of the valve seat, and also discharge the cavity retention to reduce the pollution of the medium on the valve side. In the working state, when the valve is fully open or fully closed, the valve stem stuffing box can be replaced.
The valve stem part is sealed with PTFE packing and O-ring double seal, especially suitable for gas medium. The moving part of the valve stem adopts the best SF self-lubricating bearing, which makes the friction coefficient smaller and reduces the operating torque.
