High Performance Double Offset Butterfly Valve
- High performance double offset butterfly valve for high-cycle, corrosive, and dead-end service applications
- Available in sizes 2″ – 24″ across ANSI pressure ratings 150 and 300
- Lug pattern design with bi-directional double dead-end service capability
- Drip-tight, zero-leakage performance verified per API 598
- Body materials in CF8M and WCB
Description
- High performance double offset butterfly valve offering a lightweight, cost-effective solution for demanding isolation and flow control applications requiring drip-tight shutoff and long service life
- Double offset disc geometry reduces seat wear during operation, extending service life in high-cycle and highly corrosive environments
- Bi-directional double dead-end service capability for reliable isolation from both flow directions simultaneously
- Taper pin disc-to-stem connection positioned partially within both the disc and shaft, designed to resist shear force by being exposed to compression force — significantly increasing joint strength and longevity
- Pressure-assisted, replaceable seat design suitable for bi-directional and double dead-end service; tested and verified drip-tight, zero-leakage per API 598
- Standard seat material is enhanced TFE; metal-seated and alternative seat materials available on request
- Lug end configuration for easy installation and end-of-line service
- Available in sizes 2″ – 24″ across ANSI pressure classes 150 and 300
- Body materials in CF8M stainless steel and WCB carbon steel
- Fully compliant with API 609, API 641, API 598, API 607, NACE MR0175, and ASME B16.34
