The flow control 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.
Accuracy: In the flow range of 0 to 70% the linearity of
pilot pressure to flow is about 10% accurate.
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,
subject to sleeve material

Body: stainless steel 316L, material no. 1.4435
Sleeve: depending on selected version
