# Butterfly Valves

Center Line® Series RS

## Resilient Seated Butterfly Valves

The Center Line® Series RS Butterfly Valve features advanced materials for repeatable tight shutoff in severe abrasive and corrosive environments. With only two wetted parts — the disc and the seat — neither the body nor mechanical parts are exposed to the corrosive environment.

Available in metric and DIN standards across a wide range of sizes from DN 40 to DN 1400, in wafer, lug-type and flanged body configurations.

- Replaceable cartridge seat — solid backup ring design
- Only 2 wetted parts — superior corrosion resistance
- Bi-directional shutoff — liquid and gas-tight
- Blow-out proof shaft with lock at valve neck
- ISO 5211 top flange — simple actuator mounting
- Maintenance-free DU® self-lubricating bearings
