Description:
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, non-corrosive 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 bar
- Differential pressure = max. 2.5 bar
- Closing pressure = P1 + 2.5 bar to DN32, P1 + 2 bar from DN40 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 accuracy of the linearity of pilot
pressure to flow is approx. 10%.

Mounting_position: any

Temperature_range: 0 °C to max. 100 °C / 32 °F to max. 212 °F,
subject to sleeve material

Body: POM at QP or aluminium die-cast at QS
Sleeve: depending on selected version
