Butterfly valve

The butterfly valve has a body, a resilient seat, a butterfly disk, a stem, packing, a notched positioning plate, and an actuator. The resilient seat is under compression when it is mounted in the valve body, thus making a seal around the periphery of the disk and both upper and lower points where the stem passes through the seat. Packing is provided to form a positive seal around the stem for added protection in case the seal formed by the seat should become damaged. To close or open a butterfly valve, the actuator is turned only one quarter turn to rotate the disk from 0° to 90°. Actuators used on butterfly valves vary based on the application and size of the valve. A simple handle oriented in the same direction of the metal disc (to indicate valve position) is common.

RS Series Resilient Seat Butterfly Control Valves

Valves are available in full-lugged or wafer mounting style. All bodies meet ANSI 150 pressure ratings for hydrostatic requirements. The valves are compatible with ANSI 125/150 flanges. Standard valves 2"-12" are bidirectional with a bubble-tight shut-off pressure rating of up to 250 PSI dead end service. Valves 14"-20" are also bidirectional with a bubble-tight shut-off standard pressure rating of 50 PSI. Rating to 150 PSI is available with non-undercut (NU) discs.
