Description

A lug-type butterfly valve with a ductile iron disc and EPDM seat, designed for on-off isolation in water supply, wastewater, HVAC, and general industrial pipeline systems. The lug body allows secure bolting to the pipeline and supports end-of-line service. Manual handle operation enables straightforward valve control for small to medium pipe sizes.

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 CI, DI, CS and SS, so the grade can be matched to the service rather than the other way round.

Seat and trim options are EPDM, PTFE, FKM and NBR. 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, wastewater, chemicals, air, steam and oil.

It is catalogued for Water & Wastewater, HVAC and Industrial Process.

Working temperature is -30°C to 135°C.

Built to API 609, ANSI 16.34, JIS B2064, GB/T 12238 and DIN 3202.
