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 and PPH discs and EPDM 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 pneumatic actuator controls the positions of the valve (closed / open).
