Features

• Simple structure
• Stem nut surface nitriding to improve surface hardness
• Medium flange bolts made of high-strength alloy steel with resistance to high temperatures
• Double sealing of packing and bellows for zero leakage
• Bellows located in inner cavity of valve bonnet to avoid direct media contact, extending bellows service life
• Bellows uses 2–4 layer overlap construction to prevent leakage from single-layer bellows damage and extend service life
• DN100 nominal bore visible cast on body
• PN16 pressure rating cast on body
• Material designation GS-C25 cast on body (carbon steel casting grade)
• Flanged end connections
• Handwheel operated
• Rising stem with external thread visible
• Bolted bonnet construction

Description

A bellows sealed globe valve with double sealing via packing and bellows to achieve zero stem leakage. The bellows is housed within the bonnet cavity, shielded from direct media contact, and uses 2–4 layer overlap construction. Available in carbon steel and stainless steel body materials across a wide size and pressure range.
