Pneumatic trunnion mounted ball valves with scotch yoke pneumatic actuator

Producto: Pneumatic trunnion mounted ball valves with Scotch Yoke Pneumatic Actuator

Introduction.

Trunnion mounted ball valves can be mounted with scotch yoke pneumatic actuators for  heavy duty services in fields of oil, natural gas, coal processing, mining, refining, etc

Features

1.    Symmetrical scotch yoke mechanism with more balanced torque curve;

2.    Robust trunnion mounted valve body according to ISO17292 and API6D;

3.    Solid forging stem after quenching and tempering heat treatment, making hardness HB220 ~ 250;

4.    The selection of valve packing includes braided flexible graphite seal or PTFE seals to achieve reliable tightness in certain lubrication;

5.  According to different working conditions, soft seat, metal to metal and fireproof seat can be used for major seat structure;

6.  Auxiliary sealing structure can be set at the valve seat. A grease filling valve is added to the valve seat and the stem to temporarily seal in an emergency.

7. Stem can be lengthened according to the need to be buried in the ground.

Working principle

Compressed air goes into the cylinder to push piston to move. By converting linear motion of the piston into the disk rotational motion, the disk rotation drives output shaft and thus control the valve
