N/A Designed for years of dependable service, the superior design of our butterfly valve provides ease of adjustment along with the ensured dependability expected in any distribution system or plant installation. Our butterfly valve has a 100% bubble tight seal via a 316 stainless steel ring located in the body, and rubber seat located on the vane. The rubber seat provides a ‘zero leakage’ alternative to metal-seated valves.

For pump station and treatment plant applications, butterfly valves offer flow control advantages (such as throttling) over gate valves, and are much more economical. Our butterfly valves are manufactured in accordance with the American Water Works Association (AWWA) C504 standard. Butterfly valves are constructed of ductile iron, stainless steel, rubber seats & seals. The strength of ductile iron along with stainless steel components provide corrosion resistance for buried service applications.

N/A STANDARD FEATURES

• Sizes: 3"-72"
• Heavy duty ASTM A536 ductile iron body designed and manufactured to meet or exceed AWWA standard C504.
• Offset vane design: Heavy duty A536 ductile iron meets or exceeds AWWA C504.
• EPDM rubber is vulcanized to a 304 stainless steel ring and attached to the vane utilizing self-locking, stainless steel cap screws. Body ring seat is composed of 316 stainless steel, forming an uninterrupted 360-degree seal.

• Stainless steel shafts: One-piece shaft of stainless steel meets or exceeds AWWA C504: Class 150B – 304 stainless steel Class 250B – 630 stainless steel. Other options are available.
• Direct mounted actuators: Size 3"-24" butterfly valves come standard with an integrally cast actuator mounting pad machined and drilled in accordance with ISO-5211 and MSS SP-101. This allows for direct mounting a manual and automatic actuator without the need of additional pieces or adapters, providing a more compact and rigid arrangement.
• Metal to metal: Full metal-to-metal contact, vane to shaft connection utilizing a stainless-steel torque plug.
• Strength: Traveling nut actuators are manufactured with ductile iron housing and position stops are factory preset to prevent the actuator from going beyond the open and closed positions of the valve.
• Overload protection: Up to 450 ft-lbs. of input torque against the stops (open/close) to prevent damage to the valve and actuator.
• Ease of maintenance: The vane rubber seat ring is field adjustable or replaceable. Bearings for each size butterfly valve require no maintenance.
• Vertical or Horizontal Orientation: BFVs can be mounted both vertically and horizontally.
