Flowrox™ Heavy Duty Pinch Valves
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.
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.
Neles provides 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. Neles' 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.
- Reduced total cost of ownership
- Longer lifetime
- Fast, easy and cost-efficient maintenance
Flowrox™ Heavy Duty Pinch Valves 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.

Flowrox™ LPP-T Peristaltic Pumps
Flowrox LPP-T transfer pumps incorporate advanced single roller design which eliminates friction and lowers energy consumption. They are ideal for pumping various slurries and dosing a wide range of abrasive, corrosive, viscous or crystallizing media.
Advanced Rolling Design
The operating principle of the Flowrox hose pumps is based on the peristaltic effect. As the cylindrical rotor rotates along the hose, the process medium gets pushed forward through the hose. At the same time, the hose behind the compression point reverts to its original circular shape creating a suction effect at the pump inlet port. As a result, the hose bore is re-filled with the medium. No backward flow or slip can occur as the hose is squeezed tight by the roller.
Due to their technical features, Flowrox hose pumps provide exact flow per revolution. They also incorporate an advanced rolling design, which eliminates friction, maximizes hose life and lowers energy consumption. Energy efficiency, long hose life and low maintenance generates substantial savings during the life cycle of peristaltic pumps. Lifetime of Flowrox pumps hoses is 3-5 times longer than conventional hose pumps.
Trailblazing Peristaltic Pump Technology
Flowrox LPP-T transfer pumps are equipped with a patented hose flange and reliable in-line pipe connections, as well as a hose leak detection unit. Patented adjustment mechanism senses hose wear when compression is readjusted. This helps to maximize hose lifetime and minimize the risk of over-compression. There is no need for shimming. The LPP-T100 is one of the world's largest hose pumps, with a maximum continuous flow of 100 m/h.
Flowrox™ LPP-T Peristaltic Pumps Features:
- Low Operating Cost - Advanced single roller design eliminates friction and lowers energy consumption.
- Capability to Pump 24/7 - No overheating at high continuous flow rates due to the roller design that minimizes friction and heat.
- Pumps High Solid Content Slurries - The pump design allows pumping slurries with up to 60-80% solids content.
- Long Service Intervals & Ease of Maintenance - Pump hose is the only replaceable part and can be easily changed on site.
- No Mixing or Shearing of the Medium - Enabled by the peristaltic effect.
