Series 3W/3L Resilient Seated Butterfly Valves

Offers an Industry Standard Face-to-Face with multiple Flange Drilling ASME B16 Class 125/150, EN 1092-1 PN10/16, JIS 10K, AS2129 Table D & E.

Series 3W/3L Resilient Seated Butterfly Valves

Molded-in Seat

Provides maximum body protection encapsulating all wetted surfaces of the pipe to valve flange system. Molded-in seat increases application use for higher velocity applications. With EPDM and BUNA-N seats available.

Series 3W/3L Resilient Seated Butterfly Valves

Disc to Seat Contact

Extensive design to optimize the sealing surface of the disc radius to ensure the seat and disc have the ideal interference for bubble tight shutoff while reducing torque across the full pressure range. This enhances the efficiency of your actuated package and reduces the costs from unnecessary torque and also leads to extended reliability in higher cycle applications.

Series 3W/3L Resilient Seated Butterfly Valves

Disc to Stem Connection

Milled stem flats and internally broached discs allow for an efficient transfer of torque from the valve operator to the disc.

Series 3W/3L Resilient Seated Butterfly Valves

Variety of Discs

The Series 3W/3L comes in a wide variety of disc materials to meet your needs and maximize the use in a variety of applications. Disc options including Nylon Coated Ductile Iron, Stainless Steel, Aluminum Bronze and Duplex.

Series 3W/3L Resilient Seated Butterfly Valves

Bearing support

Integral bearing support to protect the stem from side loads increases life span for the valve and actuator while reducing torque for the most efficient actuation package.

Series 3W/3L Resilient Seated Butterfly Valves
