Worm-Gear Eccentric Flanged Butterfly Valve

• Category: Valves
• Exhibitor: Tianjin Tanggu Yuwa Valve Co., Ltd. · Booth C837-838 (Hall C)

Description

The double-offset design keeps the disc and seat out of contact during opening and closing, reducing seal wear and improving reliability. The soft-seated version gives zero leakage for medium-low pressure and ambient-temperature water, HVAC and general industrial lines. The triple-offset version adds a conical seat for metal-to-metal sealing and handles temperatures from -40°C to 450°C, including steam, oil and corrosive media in petrochemical, power and metallurgy service.
