EXTREME ELECTRIC BUTTERFLY VALVE
1.
DEFINITION
Ball valve for isolating the flow in liquid handling systems.
Design based on Standard EN ISO 16136 in accordance with Directive 97/23/EC.
The valve is available with PVC-U, CPVC, PPH, PVDF and ABS discs and EPDM perox. and FPM sealing gaskets. The choice of material
for the body and gaskets depends on the type of liquid to be carried and on the working temperature of the liquid, in accordance
with the chemical resistance tables available on our website and the pressure/temperature chart in this Manual.
The electric actuator controls the positions of the valve (closed / open).
Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using sets of
bolts and no nuts.
The valve is installed between flanges using a separate set of bolts for each flange.
This setup permits either side of the piping system to be disconnected without disturbing the other side.
