Description
A lug-type butterfly valve available in cast iron, ductile iron, carbon steel, and stainless steel body materials, designed for flow control in water supply, drainage, and industrial piping applications. Offered in sizes DN50 to DN600 with nominal pressures PN10/16 and Class 150/300. Suitable for media including water, chemicals, air, steam, oil, acids, and salts.
Selection notes
This butterfly valve is a lug type pattern, supplied for lug installation.
Sizes run DN50 to DN1200, in PN10, PN16, Class 150, Class 300.
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 water, chemicals, air, steam, oil and salts.
It is catalogued for Water & Wastewater, HVAC and Industrial Process.
Working temperature is -30°C to 135°C.
Built to API609, ANSI16.34, JISB2064, GB T12238 and API 609 (face-to-face).
