Pratt Industrial OS1-150-020-89F9 Wafer Butterfly Valve, ANSI 150, 2 Inch, Ductile Iron Body, DI/ENP Disc, 410 Stem, BUNA Seat Features:
- Top flange conforms to ISO 5211 industrial standard allowing a universal mounting pad for automation requirements which is suitable for most actuators in the market.
- Blowout proof stem meets all API 609 requirements. Our unique design also creates a secondary stem journal seal preventing leakage to atmosphere.
- Shaft seal: upper shaft seal shall be a self adjusting O-ring compressed between the top (2) upper bushings creating a positve seal between the body and shaft.
- Bushing: Pratt uses three upper and one lower RTFE bushings, this reduces stem jounal friction and reduces torques. 
- Pratt utilizes 2 internally driven shafts creating a strong drive connection and allowing for less disc movement under high pressure.
 
Additional Information:
Pratt’s unique seat design utilizes 3 tongue and groove connection points to the valve body. Seats remain secure and stable even under high dead-end pressure and full vacuum services. The center tongue not only locks the seat in place, but allows rubber material to flow into the center body groove when cycling the valve, drastically reducing the operating torque.
