Approvals
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
- Through-tapped lugs allow the downstream pipe to be removed without disturbing the valve, suiting end-of-line installations
- Compact face-to-face dimension reduces spool piece length in tight plant rooms
Description
Rubber-lined wafer and lugged butterfly valve with replaceable elastomeric seat. One-piece through shaft with square internal disc-to-stem connection. Tongue-and-groove seat retention; blowout-proof shaft assembly. ISO 5211 top mounting flange for direct actuator mounting. Size range DN50 to DN1000 (wafer and lugged).
Selection notes
This butterfly valve is supplied for wafer and lug installation.
Sizes run DN50 to DN1000, in PN10, PN16, PN25.
The body is Ductile Iron GGG40.
Seat and trim options are NBR and EPDM. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
It is catalogued for Water & Wastewater, HVAC and Industrial Process.
Working temperature is -15°C to 120°C.
Built to EN 593, ISO 5752, DIN 3202, BS 5155 and API 609.
