Weidouli's Globe type control valves are combined characteristics of CV3000 flow path design with our own advantages. The development of structural design ideas, innovative design, optimization and improvement of the valve structure, suitable for a variety of harsh working conditions.
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.
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
Need stem with high finish
Not suitable for nuclear radiation (packing is easily damaged)
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
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.
