Features & Benefits

The Butterfly Valve resilient seated butterfly valves feature a one-piece body with a molded-in seat to increase the products pressure rating and ability to operate in higher velocity applications. The 3W/3L offers a high-strength through stem design utilizing an internal disc to stem connection to reduce hysteresis.

The Series  is engineered to provide bidirectional bubble-tight shutoff and isolation of the line media from the stem or valve body. Available in Buna-N and EPDM elastomers as well as Nylon Coated and stainless disc materials it offers a solid platform for a variety of applications. The ISO 5211 top flange allows for easy automation to pneumatic or electric actuation for on/off or modulation applications.
