WPV

double eccentric butterfly valve

Our Butterfly Valve was designed for the water industry, taking into account the best available double offset technology, exceeding the requirements of EN 593 and AWWA C504. The disc is streamlined by computer-optimisation for low headloss. Quality, self-locking worm gear actuators are included, with a wide choice of operational options.

How the Valve Operates

Designed speciﬁcally for corrosive applications. The body and seat are designed to assure non-clogging shut-oﬀ/on suspended solids. The valve can be manufactured with replaceable sleeves.

Applications

The valve is suited for pumping stations, treatment plants, reservoirs, pipelines, power stations, desalination plants & industrial applications.

Actuators

All types of actuators can be fitted; electric, hydraulic, pneumatic, handwheel and worm gear.
