WEGEN / ROWEFLEX Flexible Compensators & Diverter Valves
Global supply of WEGEN / ROWEFLEX flexible rubber compensators, 2-way diverter valves, and pinch valves for bulk solids processing plants. Direct sourcing and technical selection from SpareX.
ROWEFLEX Elastomer Flexible Hose Expansion Joints
ROWEFLEX flexible hose compensators are engineered for bulk solids handling and powder transport piping. They absorb thermal expansions and misalignment while decoupling vibrations from mixers and hoppers. The elastomer body prevents stress transfer to load cells.
- Elastomer sleeves formulated from NR, NBR, EPDM, and silicone compounds
- Compensation of axial and angular misalignment with scale vibration decoupling
- Smooth internal bore without dead zones to eliminate material accumulation
- Replaceable elastomer sleeves, clamping rings, and quick-release collars
ROWEFLEX 2-Way Diverter Valves for Bulk Solids
ROWEFLEX 2-way diverter valves and heavy-duty HD models route bulk powders across pneumatic lines. The internal self-cleaning elastomer trouser sleeve eliminates metal contact in the product stream. Dual shaft sealing ensures dust-tight switching with zero leakage.
- Self-cleaning elastomer trouser insert for sticky and abrasive powder conveying
- Complete absence of internal metal parts for hygienic food and pharma lines
- Pneumatic rotary actuator with double dust-tight shaft gland packing
- Replaceable elastomer trouser inserts, pivot brackets, and limit switches
ROWEFLEX Pinch Valves for Dust-Free Shutoff
ROWEFLEX QSO pinch valves feature dual linear pneumatic actuators for immediate product stream shutoff. When opened, the full container bore is released for rapid discharge without restriction. The flexible sleeve reliably seals abrasive pellets, carbon black, and powders.
- Full bore passage without flow restriction for pellets, powders, and soot
- Twin linear pneumatic cylinders for balanced bilateral sleeve compression
- Completely dust-tight closure with FDA-grade elastomer sleeve options
- Replaceable QSO elastomer pinch sleeves, actuator rods, and solenoid valves
ROWEFLEX Pneumatic Inflatable Sealing Sleeves
ROWEFLEX inflatable sleeves deliver dust-free clamping of Big Bag filling spouts during bagging cycles. Available in Basic and Standard Plus models, the sleeve expands with air to seal the spout securely. This eliminates powder dusting, saves material, and protects operators.
- Pneumatic expansion chamber for dust-tight clamping of bulk bag inlets
- Basic model with clamp band mounting and Standard Plus extended travel design
- Electrically conductive antistatic elastomers for hazardous ATEX plant areas
- Replaceable inflatable rubber bladders, air fittings, and mounting rings
ROWEFLEX Slide Diverters for Twin Extruders
ROWEFLEX slide diverters continuously split dry bulk flows evenly between two parallel processing paths. The geometry is optimal for charging twin side extruders from one hopper. The resilient internal elastomer lining resists abrasion from mineral fillers and polymers.
- Proportional stream dividing for balanced charging of two side extruders
- Highly resilient rubber lining offering superior resistance to abrasive fines
- Direct integration into existing vertical gravity chutes without modifications
- Replaceable elastomer divider inserts, slide blades, and sealing hardware
ROWEFLEX Specialized Proprietary Elastomer Grades
WEGEN offers 45 proprietary elastomer compounds formulated for flexible bulk components. The portfolio spans FDA and EU 1935/2004 compliant NR and EPDM grades, oil-resistant Neo chloroprene, and AS hell antistatic rubber. The compounds maintain elasticity under cyclical loads.
- Raw material inventory of 45 compound grades for custom industrial components
- FDA and EU 1935/2004 food contact approvals for sanitary powder handling
- Conductive antistatic compounds preventing electrostatic charge buildup
- Vulcanized flange gaskets, sealing strips, and elastomeric test specimens
Engineering Advantages of ROWEFLEX Hose Compensators
ROWEFLEX compensators are flexible elastomer hose expansion joints engineered to absorb thermal expansions, piping misalignment, and mechanical vibrations.
The resilient elastomer sleeve isolates dynamic forces from rotating mixers and blowers, safeguarding steel plant structures and sensitive weighing hoppers from mechanical stress.
In processing systems featuring loss-in-weight feeders, blenders, and vibrating screens, rigid pipe connections introduce false load cell readings and weld fatigue.
Installing flexible connectors with smooth internal bores eliminates product accumulation and guarantees uninterrupted bulk material transfer.
Bulk Flow Diversion Technology with 2-Way Diverter Valves
ROWEFLEX 2-way diverter valves feature a self-cleaning elastomer trouser sleeve without internal metal parts for hygienic bulk material diversion.
The flexible trouser insert continuously self-cleans through elastic deflection during flow switching, preventing product buildup and clogging when handling cohesive powders.
The external actuation linkage includes dual shaft gland packing to stop fine dust escaping into the plant atmosphere. This design complies with strict industrial hygiene and safety regulations across food, infant formula, and active pharmaceutical ingredient processing facilities.
