WESTAD Butterfly valves

0.00

Butterfly valves regulate or isolate the flow of a liquid medium by means of a rotatable disk. Similar to ball valves, butterfly valves are also characterized by their quick operation. As a quarter-turn valve, fully opening or closing the valve is achieved by rotating the disk a quarter of a turn.

The WESTAD butterfly valves are designed to meet demanding challenges in terms of different media, pressure and temperature. Ideally, they are used for LNG, LPG, chemical and other critical applications. The housing is available in the dimensions DN 80 to 1000.
