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

Resilient seated wafer butterfly valve with EPDM/NBR rubber seat moulded onto the valve body. Pinless shaft-to-disc connection and epoxy-coated body provide corrosion resistance and long service life. Bi-directional bubble-tight shut-off; ISO 5211 top flange for direct actuator mounting.

Selection notes

This butterfly valve is supplied for wafer installation.

Sizes run DN50 to DN300, in PN10, PN16.

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.

Built to EN 593, ISO 5752, DIN 3202, BS 5155 and API 609.
