MPI McWane – Butterfly Valves

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.

ADDITIONAL FEATURES

• 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.
