- There are wide materials selection of valve castings body and internal parts which can suit special working conditions;
- The trim structure of the control valve can reduce the noise level, improve the anti-cavitation and anti-flashing performance, and eliminate the blocking flow;
- The flow coefficient range is large, and the adjustable ratio range is large;
- The good design of metal bellows seal can prevent leakage of corrosive and highly toxic medium and pollution
- Easy to disassemble and install the valve trim, easy to inspect and maintain for control valve ;
- Surface treatment technology is advance, such as polishing, Stellite alloy, heat treatment, chromium nitride coating, which make the control valve have a long service life and reliable operation;
- The direct and reverse acting is realized by the cooperation of the pneumatic diaphragm multi-spring actuator, and the spring range (the number of springs is unchanged) can be changed without adding other parts;
- The operation mode can be pneumatic, electric and electro-hydraulic
- A manual operating mechanism, like a handwheel, can be installed on the side or top of the actuator.

Note:
- Above structure, the seat is metal sealing, PTFE soft sealing is VI-grade as an option, also can provide stellite hard seal. As per actual working temperature, we may choose the proper bolt & nut
- PTFE V type stem packing is with graphite, the working temperature can be higher than 232℃(450F)
- The common body material is WCB and S.S can apply with other high corrosion resistance alloy
