Butterfly Valves
Series DBF-03 Full Lug and DBF-04 Wafer
Sizes: 2" - 12" (50-300mm) 200psi (13.8 bar)
Watts Series DBF resilient seated butterfly valves are available in sizes 2"-12" (50-300mm), wafer or lug body design. This series was designed to meet the stringent requirements for HVAC, Irrigation, OEM, Commercial and Institutional applications, and wherever positive shutoff is required for liquids, gases, and slur­ries. Incorporating a 200psi (13.8 bar) pressure rating for 2"-12" (50-300mm), the Series DBF is standardly constructed of a ductile iron body, an aluminum bronze, ductile iron or 316SS disc, and a 416SS or 316SS shaft. Standard seat materials available include Buna-N, EPDM, and Viton seat prevents the seat from collapsing or dislodging. In addition to the above features, the Series DBF mounting pad is designed to ISO 5211 standard to accommodate lever handles, gear operators or actuator.
The Watts Series DBF butterfly valves are designed and manu­factured for use with ANSI 125 or 150 Class flanges and to comply with API 609 and MSS-SP-67.

Features
Operators Ten-position handle is standard. An infinite positioning/locking handle is also available on valve sizes 2"-12" (50-300mm). The infinite position Pos-Lok throttle plate incorpo­rates a memory stop and a padlocking device in the fully closed position. Manual, worm-gear operators are available for all valves and are recommended on 8" (200mm) and larger sizes. Watts butterfly valves are also available with electric or pneumatic actuators and chain wheel operators to satisfy a wide variety of requirements.
Shaft
One-piece shaft delivers positive disc-to-seat location
with maximum strength. 416SS is standard with aluminum bronze and ductile iron discs and 316SS shaft with stainless steel disc.
Shaft Bushings – Duralon for proper shaft alignment and minimal shaft deflection.
Shaft Seal
seal prevents external contamination of stem area and provides a backup seal to the primary shaft seal formed by the disc/seat interface.
Body
and Wafer (DBF-04) types 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 standard body material is ASTM A-536
ductile iron.
To prevent shaft leakage, the bidirectional shaft
Watts Butterfly Valves are available in Full Lug (DBF-03)

bushings (3) provide shaft support
Disc Disc edge is machined and polished 360° to assure leak- tight shutoff while minimizing operating torque. Positive, disc-to­shaft connection is provided by stainless steel precision taper pins that are vibration proof.
Seat – Phenolic-backed, non-collapsible, resilient seat is me-
chanically secured to provide dead-end service to the full 200psi (13.8 bar) pressure rating. Seat face eliminates the need for flange gaskets. Full 360° sealing isolates the body components from the media and provides the primary shaft seal. Available in EPDM, Buna-N, and Viton
