        Description:
        The 2-port/2-way valve functions as a pinch valve in a new design
 of housing with full flow cross-section. Since the straight valve
 passage has neither constrictions nor back-points, there is no danger
 of clogging or blockage. Frictional loss is at a minimum.
 
 Media:
 compressed air, gases, liquids or other paste-like or powdery media
 Solids are enclosed by the flexible sleeve at shut-off.
 
 Sleeve: Highly flexible with double woven reinforcement in eight
 different grades. Sleeve simple to change.
 
 Pressures:
 Operating pressure = max. 4.0 bar
 Pilot pressure = max. 6.5
 Differential pressure = max. 2.5 bar
 Closing pressure = P1 + 2.5 bar to DN 32, P1 + 2 bar from DN 40 on
 
 Vacuum: If vacuum is greater than -100 mbar, vacuum compensation
 should be provided on the control side.
 
 Mounting_position: any, at horizontal mounting pilot port
 preferably at the top
 
 Temperature_range: 0 °C to max. 100 °C / 32 °F to max. 212 °F,
