Trunnion Ball Valve

Product Introduction：

High-pressure forged steel Trunnion Ball Valve is mainly divided into two types of sealing, one is Metal Seated, the other is Soft Seated,The difference between Metal Seated Forged Steel Trunnion Ball Valve and Standard Soft Seated Trunnion Ball Valve is that the latter is Soft Seated valve seat, while the ball and valve seat of the former are hardened by special process，There are many ways of hardening, such as the ball and valve seat are integrated nitriding, flame spraying Hardfacing, etc. (not limited to this)，The choice of hardening method depends on the working medium or user requirements；High temperature Metal Seated forged steel Trunnion Ball Valve is widely used in petroleum, chemical industry, metallurgy, paper making, electric power, mining and other industries, especially in the medium with high temperature and various dust and solid particles.

Product Features：

1、The main parts and components are forged products with dense materials and guaranteed safety performance.

2、The movable metal valve seat structure with cylindrical spring or wave spring preload is adopted,The design of sealing preload is reasonable, and the closing and opening are flexible, effectively ensuring the reliability of sealing.

3、The ball is made of wear-resistant alloy powder by supersonic spraying,The seat is also treated by surfacing Stellite carbide and spraying other super wear-resistant alloy materials.

4、The sealing surface is carefully polished, and the sealing is reliable and guaranteed.

5、Full-path channel design, small flow resistance and large flow capacity.

6、It’s anti blowout stem design is safe and reliable, and the anti-static function can be designed according to requirements.

7、Automatic pressure relief seat design，Once the cavity in the body is abnormally pressurized, the valve seat will automatically release to the end with low pressure, which is safer.

8、The upper and lower valve stems are designed with bearing structure, and the torque is lighter during opening and closing.

9、Various of Operation Modes：Manual, worm gear, pneumatic, electric, hydraulic, pneumatic-hydraulic, etc; It can also be used together with transportation control automation.
