Features
- Double eccentric structure design
- Interchangeable PTFE seats compatible with a variety of working conditions
- Anti-blowout stem design
- Low-leakage carbon fibre bowl-type combined packing structure available for fugitive emission service, meeting ISO 15848 and API 622
- Tangential stem pin is half in the disc and half in the stem; tangential positioning transfers squeeze force rather than shear stress to the connection
- ISO 5211 top flange for mounting pneumatic, electric, and gas-liquid linkage actuators
- Double-flanged butterfly valve with worm gear (handwheel) actuator
Description
Double eccentric high-performance butterfly valve, available in sizes NPS 2" to NPS 48" (DN50 to DN1200), pressure ratings Class 150 to Class 300 and PN10 to PN50. Body materials include carbon steel and stainless steel grades; seating in PTFE and PTFE composites. Suitable for petroleum, petrochemical, natural gas, power, and water conservancy industries.
Selection notes
This butterfly valve is a high-performance and double eccentric pattern, supplied for wafer, lug and flanged installation.
Sizes run DN50 to DN1200, in PN10, Class 150, Class 300.
The body is offered in WCB, A351 Gr CF8, A351 Gr CF8M and A351 Gr CF3M, so the grade can be matched to the service rather than the other way round.
Seat and trim options are PTFE, PTFE+GLASS FIBRE, PTFE+GRAPHITE and RPTFE. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
Stated service media include petroleum, petrochemical, natural gas, electric power and water.
It is catalogued for Water & Wastewater, Oil & Gas and Industrial Process.
Working temperature is -196°C to 300°C.
Built to API 609, MSS SP-67, API 609 (Face to Face), API 622 (Fugitive Emissions) and DIN 3202.
