Forged steel high pressure ball valve

Product Overview

Forging steel high-pressure ball valve closing part ball rotates around the center line of the valve body to open and close. The sealing element is embedded in the stainless steel valve seat, and the end of the metal valve seat is provided with a spring. When the sealing surface is worn or burned out, the valve seat and the ball form a metal seal under the action of the spring. It has a unique automatic pressure relief function. When the medium pressure in the valve chamber exceeds the spring preload, the valve seat at the outlet end will retreat away from the ball to achieve the automatic pressure relief effect. After pressure relief, the valve seat will automatically reset. It is suitable for general working media such as water, solvent, acid and natural gas, and also suitable for the medium with bad working conditions, such as oxygen, hydrogen peroxide, methane and ethylene The industry has been better applied.

Structural characteristics

1. All parts of the product are forgings.
2. The bottom mounted valve rod is adopted, and the inverted sealing structure is set to ensure the reliable sealing at the packing and prevent the valve rod from falling out.
3. Inlaid valve seat is adopted. O-ring is set behind the valve seat to ensure no leakage of medium.
