Features & Benefits
- 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 of manual and automated actuators without the need of additional pieces or adapters, providing a more compact and rigid arrangement.
- Stainless steel meets or exceeds AWWA C504: Class 150B – 304 stainless steel Class 250B – 630 stainless steel. Single-piece (3”-12”). Two-piece (14”-72”).
- Butterfly Valve Bodies consist of heavy duty ASTM A536 ductile iron that are designed to meet or exceed AWWA C504.
- EPDM rubber is vulcanized to a 304 stainless steel ring and attached to the vane utilizing self-locking, stainless steel cap screws. The body ring seat is composed of 316 stainless steel, forming an uninterrupted 360-degree seal. Butterfly Valve vane rubber seat ring is easily field replaceable.
- Heavy duty A536 ductile iron meets or exceeds AWWA C504.
- Self-adjusting V-type packing that increases the sealing force with the increase in line pressure. Accessible without dismantling the valve, per AWWA C504.
- Full metal-to-metal contact, vane to shaft connection utilizing a stainless steel torque plug.
- Nylon bearings are sized to meet or exceed the AWWA C504 specification for axial pressure loads. The bearings are self-lubricating and require no maintenance.
