Pinch Valves for shut-off and control applications

Flowrox pinch valves are ideal solutions where shut-off and control applications involve abrasive or corrosive slurries, powders or coarse substances.
Flowrox provides pinch valves with enclosed, open, sealed and general line valve bodies.  We provide tailor-maid flow control solutions precisely in accordance with the customer specification.

Flowrox Pinch Valve Portfolio includes:


PVE and PV pinch valves

PVE (enclosed body) and PV (open body) pinch valves are ideal for demanding flow control and shut-off applications.


Modular Design

Flowrox modular pinch valve design has three main components: the sleeve, the body and the actuator (manual, pneumatic, hydraulic and electric).  The construction and materials of these components can be tailored to suit your process conditions.

  • Size range: standard range from 25 mm to 1.000 mm
  • Temperatures: -50°C to +160°C
  • Operating pressures: vacuum to 100 bar


Operating principle

In the open position, valves are at full bore with no flow restrictions. During closing, two pinch bars squeeze the sleeve shut on the centerline.



  • Full bore structure with 100 % tight shut-off
  • The inside sleeve is the only part in contact with the process medium
  • Self-cleaning Flowrox valves provide seal tight shut-off even if solids have built up on the sleeve wall. When compressed, any crystallized particles flake off the sleeve surface.
  • Inside sleeve tailored to suit specific process conditions


PVG Pinch Valve

We introduce new and cost effective PVG valve for processes involving pressure resistance, abrasion, corrosion and aggressive slurries.

The PVG valve is a general line pinch valve with strong metal body, simple bullet closing mechanism and opening tags in the inside sleeve as standard. There are several dimensions available from 50mm to 250mm and they are available with manual, pneumatic or electric actuators.

Process benefits:

  • Reliable operation of the valve
  • Opening tags in the sleeve to ensure the opening
  • No jamming or clogging
  • Breaks any possible scaling when closed
  • Full bore design: free flow of the medium, least pumping energy required
  • Low maintenance costs
  • Long service intervals

--> Reduced total cost of ownership
