Product name：Stop valve with bellows
Product introduction：Globe valve with bellows to ANSI/ASME standards, with flange or welding sleeve, with cover flange, external spindle thread and clevis, integrated base, graphite gland, flat gasket made of stainless steel. Available in the material versions WCB, CF8/CF8M with Trim Material 13% Cr, 13 Cr + Stellite, SS316/SS304 with Stellite. The bellows as primary seal prevents the medium from penetrating the gland and thus any escape of the valve to the outside.
Application：
1. Nuclear power plants
2. Thermal power plants
3. Food industry
4. Pharmaceutical industry
5. Refinery equipment
6. LPG and LNG
7. Chemical industry
8. Petrochemical industry
9. Pulp/paper industry
Advantages：
1. Double shaft seal consisting of bellows and safety stuffing box minimizes leakage to the outside.
2. The bellows cover the shaft, so the sealing gland area is not exposed to the medium
3. The bellows ensures a long service life of the internal parts. The bellows reduce the impact loads on the internal parts
4. Protect the environment from toxic substances by minimizing the discharge of the valve
