FPV

Pinch Valve Enclosed Body

The FPV Pinch Valve consists of a tough, but flexible full bore sleeve, which forms part of the pipeline. The valve is closed mechanically via movement of the pinch bars located on opposite sides of the sleeve. The core of the FPV Pinch Valve is the sleeve. The sleeve is reinforced with high-strength fabric. The valves are well suited for on/off throttling applications where scale build-up is a problem.

How the valve operates

In the closed position, the upper and low bars compress the sleeve to form a bubble-tight seal, even on entrapped debris. The valve can be used to throttle the flow.

Applications

The valve is suited for mining and mineral processing, power generation, sand/gravel, chemical & soda ash, pulp & paper, environmental, effluent, dry feeds and powders.

Actuators

All types of actuators can be fitted; electric, gearbox, hydraulic, pneumatic and handwheel.

Sleeve material

FPV offers the following alternative sleeve materials, providing chemical and abrasive resistance to most media such as:

  • EPDM rubber
  • Natural black rubber
  • Neoprene rubber
  • Nitrile rubber
  • Red rubber
