Valve Body of Globe Type Control Valves


1. The interior of the valve adopts an S-shaped flow path, the entire valve body flow path is closer to the flow line than the traditional ball design, reducing the body resistance coefficient and increasing the flow capacity of the valve body.


2. The distributor in the valve effectively eliminates the rotating swirl caused by the medium flow and improves the flow capacity and the stability of the valve.

Valve Trim of Globe Type Control Valves


1. Excellent design and advanced processing technology ensure the IEC required control accuracy.


2. Modular structure can choose the best material and processing technology according to different functional requirements, can improve the service life of products and convenient valve maintenance and valve trim replacement.


3. Self-centering structure: The valve can be sealed strictly when it is closed, without precise grinding.


Advanced combined stuffing seal


Any structure and any material has its good and bad points. They can complement each other and achieve the best sealing effect by ingenious combination design and reasonable collocation.

 

V type PTFE packing structure 


  • Low friction without lubrication                       

  • Suitable for a variety of media                   

  • Packing ring is loaded by a belleville spring and automatically adjusted

  • Working temperature:-40℃-230℃

  •  Need stem with high finish

  •  Not suitable for nuclear radiation (packing is easily damaged)


V Type PTFE Packing Structure


Graphite packing structure


  • High working temperature

  • Temperature reach 649℃

  • The packing ring is loaded by a Belleville spring and automatically adjusted

  • Suitable for a variety of media and nuclear radiation applications

  • Long service life

  • Need to lubricate when in high working temperature

  • High friction, easy to produce hysteresis

Actuator 


AM pneumatic film actuator can provide greater output force than traditional actuator since it adopts innovative high-strength rolling diaphragm design, and the air supply pressure can reach 0.6MPa. At the same time, the precision of the actuator is greatly improved with the constant effective area of the diaphragm and the high precision spring. 


AA additional devices, to improve the performance, increase function, and expand the application of the control valve, such as positioner, handwheel mechanism, booster, etc.
