Flowrox™ heavy duty pinch valves
Pinch valves for shut-off and control applications
Flowrox PV, PVE and PVE/S heavy duty pinch valves are designed for shut off and control applications involving abrasive or corrosive slurries, powders or granular substances. In the open position, the valve is full bore with no flow restrictions. During closing, two pinch bars squeeze the valve sleeve shut on the center line. Bubble tight shut-off is provided even if solids have built up on the sleeve wall.
Benefits & features
Improved process efficiency
100% tight shut-off even if solids have built upon the sleeve wall. When compressed, any crystallized particles flake off the sleeve surface.
Improved customers' productivity
Full bore: Ensured free flow of the medium and less pumping energy is required.
Ease of maintenance
Only the sleeve is in contact with the medium and is the only replaceable part. Can be easily changed on site.
Accurate control
Improved controllability with conical sleeve results in linear control curve.
Extended service intervals
High corrosion resistance and flexible sleeve.
Industry benchmark in pinch valves
Flowrox industrial valves are benchmark in heavy duty industry and most demanding conditions. Flowrox heavy duty pinch valve is made to last and is ideal where shut-off and control applications involve abrasive or corrosive slurries, powders or coarse substances. The rubber sleeve is the only wearing part which significantly reduces maintenance costs and extends service intervals. Advanced flow control solutions paired with superior valve and elastomer technology meet even the most demanding customer specifications.
We provide tailor-made flow control solutions precisely in accordance with the customer specification.
- Typical payback time 15 months in on/off applications
- Save 2/3 on spare part costs
- Reduce downtime costs by 70%
- We offer comprehensive sizing and selection service
- Low cost maintenance and long service intervals – the inside sleeve is the only replaceable part
Designed for demanding control applications
Flowrox control valves are designed for demanding control applications in which conventional valves encounter problems with wear due to increased turbulence. Controllability can be further improved, i.e. linearized and widened, with conical sleeves and smart positioners.
Each valve can be sized and optimized for the optimal control range, to limit wear and velocity and also to prevent cavitation from occurring in the control valve. Our control valve sizing program is available to ease your work. Flowrox control valve sizing is based on international IEC60534 standard (harmonized with ANSI/ISA S75).
Flowrox extra thick polyurethane sleeve
Special for harshest control applications
For high-wear control valve applications, we can also provide Flowrox extra thick polyurethane (PU) sleeve. It is engineered for extreme sliding abrasion, low angular and low velocity impact conditions. For more information, click here.
- Reduced total cost of ownership
- Longer lifetime
- Fast, easy and cost-efficient maintenance
Only part in contact with the abrasive slurry is the abrasion-resistant polyurethane inner lining of the sleeve.

Flowrox™ PVG and PVEG pinch valves
Flowrox PVG and PVEG pinch valves are robust and cost effective with simple, single-sided closing mechanism. PVG valve has a strong valve body and opening tags in the sleeve as a standard. PVEG valve has a corrosion resistant and light-weight plastic body. Through the reliability and structure, both kinds of valves offer substantial savings based on improved performance, long service lifetime and low total cost of ownership. Flowrox PVG and PVEG valves are ideal for low cycle applications involving abrasion, corrosion and aggressive slurries
Flowrox™ slurry knife gate valves
Heavy duty slurry knife gate valve isolates flow even in the most demanding process conditions. The bi-directional flow tolerates backflow and elastomer sleeves on both sides of the gate provide tight shut off. Flowrox knife gate valve follows the concept of the ease of maintenance. The valve body is cast in one piece which eliminates the need for sealing between the body halves. Load distribution ring is integrated into the valve sleeves. The valve contains only two service parts; ring sleeves and secondary seal.
Spare parts for Flowrox™ valves
We manufacture and deliver high-quality spare parts for all Flowrox™ valves. Genuine parts ensure that they are certified and specifically suited for your process. Elastic sleeve is the core of the FlowroxTM valve. It is the only part in contact with the process medium.
