Features
- Metal bellows used as the dynamic sealing element, replacing traditional packing seal
- Bellows completely isolates valve stem from medium, preventing leakage through valve stem outer surface
- Metal bellows capable of withstanding high pressure with stable sealing performance
- No packing friction; low valve stem movement resistance, improving adjustment accuracy and response speed
- Eliminates risk of valve stem jamming caused by particle ingress or packing hardening
- S-flow channel passage in valve body for low pressure drop loss and high flow rate
- Wide adjustable ratio and high flow characteristic accuracy
- CSW701/CW701: top-guided single-seat structure
- CW702/CLW702: pressure-balanced cage-guided structure
- CLW702: additional sealing ring between valve core and valve cage for reduced leakage
- Compatible with RSMF series actuators for compact structure, large output force, and long service life
Notes
- Operator options listed as pneumatic, electric, etc. — additional actuator types available on enquiry
Description
A series of bellows-sealed control valves comprising single-seat (top-guided), cage-guided (pressure-balanced), and low-leakage cage-guided variants. All variants employ a metal bellows as the primary dynamic sealing element, completely isolating the valve stem from the medium to eliminate external leakage. The valve body incorporates an S-flow channel passage for reduced pressure drop loss and wide adjustable ratio.
