Features
- Pinless shaft-to-disc connection provides stronger, fixed coupling and keeps the stem firm during operation
- EPDM/NBR rubber seat moulded onto the body ensures full corrosion resistance and bi-directional bubble-tight shut-off
- Hard-back seat design: dimensionally stable sealing surface, minimal seat wear, blow-out proof and field replaceable
- One-piece seat has integral O-ring for upper and lower shafts, working with disc edge hub to provide a double stem seal
- Epoxy-coated body for corrosion resistance, maximising service life
- ISO 5211 top flange for direct actuator mounting
Description
Compact wafer-lugged design for tight installations. The Alpine wafer-lugged butterfly valve offers the space saving of a wafer design with the dead-end service capability of a lugged body. Through-tapped lugs allow the downstream pipe to be removed without disturbing the valve, making it suitable for end-of-line installations. Compact face-to-face dimension reduces spool piece length in tight plant rooms.
