Description

Wafer-type butterfly valve with PTFE seat and stainless steel construction, fitted with a pneumatic actuator for automated flow control. Available in sizes DN50 to DN300, rated to PN10/PN16 and ANSI 150 to 300 lb pressure classes. Suitable for a wide range of media including water, steam, chemicals, oils, acids, and salts across a working temperature range of -20 °C to 180 °C.

Selection notes

This butterfly valve is a wafer type and pneumatic actuated pattern, supplied for wafer installation.

Sizes run DN50 to DN300, in PN10, PN16, Class 150, Class 300.

The body is offered in CI, DI, WCB and SS, so the grade can be matched to the service rather than the other way round.

Seat and trim options are PTFE, EPDM, 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 chemicals, air, water, steam, oil and salts.

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

Working temperature is -20°C to 180°C.

Built to API609, API609 (face to face), BS5155, DIN3202 and ISO5752.
