Series BF-03-M2 Full Lug and BF-04-M2 Wafer
Sizes: 2" 12" (50 300mm)

Watts Series BF resilient seated butterfly valve is available in sizes 2" 24" (50 600mm) in wafer or lug body
design. Wafer body design features lifting lugs while lug body design features dead-end service.
Incorporating a 200psi (13.8 bar) pressure rating for 2" 12" (50 300mm) and a 150psi (10.3 bar) pressure
rating 14" 24" (350 600mm), the BF series butterfly is standardly constructed of a ductile iron body with a
choice of either ductile iron, aluminum bronze, or 316 stainless steel discs and 416 stainless steel or 316
stainless steel shaft. A phenolic-backed seat (2"-12", 50-300mm) or aluminum-backed seat (14" 24",
350-600mm) prevents the seat from collapsing or dislodging. Standard seat materials available include
EPDM, Buna-N and Viton. The BF Series mounting pad is designed to ISO 5211 standard to accommodate
lever handles, gear operators, or actuation.
The Watts Series BF butterfly valves are designed and manufactured for use with ANSI 125 or 150 Class
flanges and comply with API 609 and MSS-SP 67 standards to meet the stringent requirements of HVAC,
Irrigation, OEM, Commercial, Institutional, and Industrial applications. Features: Body Available in Full Lug (BF-03-M2) and Wafer (BF-04-M2) styles designed for use between ANSI
125 and 150 flanges. Face-to-face dimensions comply with API 609 and MSS-SP-67. All valves are
designed to accommodate 2" of insulation. The mounting pad is designed to ISO 5211 standard.
The body material is ASTM A-536 ductile iron. Disc Disc edge is machined and polished 360 degrees to assure leak-tight shutoff while minimizing
operating torque. Positive, disc-to-shaft connection is provided by stainless steel precision taper pins.
Discs are available in ductile iron, aluminum bronze, or 316 stainless steel. Seat Phenolic or aluminum backed, non-collapsible, resilient seat is mechanically secured to provide
dead-end service to the full pressure rating in lug style valves. Full 360 degrees sealing isolates the body
components from the media and provides the primary shaft seal. Seats are available in EPDM,
Buna-N, and Viton. Shaft One-piece shaft delivers positive disc-to-seat location with maximum strength. 416SS is
standard shaft with ductile iron and aluminum bronze disc. 316SS shaft is standard with 316SS disc
models.Three shaft bushings provide shaft support for proper alignment and minimal shaft deflection.
Bi-directional shaft seals prevent external contamination of the stem area and provide backup for the
primary shaft seal formed by the disc/seat interface. Handle ISO 5211 top work design allows for standard 10 position handle 2" 6" (50 150mm) and
manual, worm gear operators for 8" 24" (200 600mm) sizes. An infinite positioning locking handle is
an available option on 2" 12" (50 300mm) valves. The posi-lok handle provides an infinite position
stop, a memory stop, and a pad-locking device in the fully closed position.Category: Valves => Butterfly Model: BF-03-121-10-M2 5Size: 5 IN
