Gas pipeline flange ball valve-Gas valve series-燃气阀厂家-上海冠环阀门制造有限公司

Product Overview

A type of valve in which the sealing element of the petroleum balloon valve rotates around the centerline of the valve body to achieve opening and closing. The sealing element is embedded in the valve seat, and a spring is installed at the end of the metal valve seat. When the sealing surface is worn or burned, the spring pushes the valve seat and the ball to form a metal seal. It has an automatic pressure relief function. When the pressure of the medium in the valve chamber exceeds the pre tightening force of the spring, the valve seat at the outlet end retracts from the ball, achieving an automatic pressure relief effect. After pressure relief, the valve seat automatically resets, suitable for general working media such as water, solvents, acids, and natural gas, and also suitable for harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. It has been widely used in various industries.
