Description
Wafer-pattern butterfly valve with resilient seat, available in multiple body and disc material options. Designed for 90-degree on/off operation with minimised operating torque. Suitable for water distribution, HVAC, and general industrial applications. Available in nominal pressures PN10 and PN16, with sizes from DN50 to DN1200.
Selection notes
This butterfly valve is a wafer type pattern, supplied for wafer installation.
Sizes run DN50 to DN1200, in PN10, PN16, PN25.
The body is offered in Cast Iron, Ductile Iron, Carbon Steel and Stainless Steel, so the grade can be matched to the service rather than the other way round.
Seat and trim options are EPDM, NBR, PTFE and FKM. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
Stated service media include fresh water, sewage, sea water, air, vapour and oils.
It is catalogued for Water & Wastewater, HVAC and Industrial Process.
Working temperature is max 150°C.
Built to MSS SP-67, API 609, EN 593, ISO 5752 series 20 and BS 5155.
