STRAIGHT-THROUGH PINCH VALVE
The KLEP Straight-Through 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 a pinch valve gate located above the sleeve. The core of the KLEP Straight-Through Pinch Valve is the sleeve. The valves are well suited for on/off and throttling control applications involving slurries, powders, liquids, granulated materials and applications where scale build is a problem.

How the valve operates
As the valve cycles downwards, the Pinch Mechanism will start to compress the soft rubber sleeve, from the top of the valve only, Therefore achieving a 100% drip tight closure, even with solids in the medium.

Applications
The valve is suited for mining and mineral processing, power generation, sand/gravel, chemical & soda ash, pulp & paper, environmental & effluent.
Actuators
All types of actuators can be fitted; electric, gearbox, hydraulic, pneumatic and handwheel.
Sleeve material
KLEP offers the following alternative sleeve materials, providing chemical and abrasive resistance to most media such as:
- Natural Red Rubber
- Natural Black Rubber
- Neoprene Rubber
- Nitrile Rubber
- EPDM Rubber
- Reduced port sleeve for throttling applications.
