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.

Main spare parts for valves are rubber sleeves. Elastic sleeve is the core of the Flowrox valve. It is the only part in contact with the process medium. Maintenance is easy as sleeve change requires no special tools. Technologically advanced Flowrox rubber sleeves guarantee high wear and corrosion resistance, a trouble-free operation, and extended lifetime. Our sleeves are 100% tight. Standard Flowrox PV, PVE and PVG sleeves are equipped with opening tags to ensure full valve opening in all process conditions.

Sleeve: robust heart of the pinch valve

Technologically advanced Flowrox sleeves guarantee high wear resistance, corrosion resistance, a trouble-free operation, and extended lifetime. Our sleeves are 100% tight.

Flowrox rubber sleeves are handmade layer by layer in a quality process covered by ISO 9001:2015 and ISO 14001:2015. Sleeve has a reinforced construction, making them the pressure retaining part of the valve. Standard Flowrox PV, PVE and PVG sleeves are equipped with opening tags to ensure full valve opening in all process conditions.

Several sleeve design options including a conical sleeve for control valves and a vacuum sleeve for negative pressure applications are available. Maintenance is easy as sleeve change requires no special tools.

The standard sleeve design consists of three sets of layers: the inner layer, the reinforcement layer and the outer layer.

Special sleeve design options include:

  • Conical sleeve for control valves
  • Suction (vacuum) sleeve for negative pressure applications
  • SensoMate sleeve detecting and signalling critical wear
  • Polyurethane lined sleeve with improved protection against wear in abrasive control applications
  • FDA requirements fulfilling food quality rubbers with white inner lining
  • Elastic and soft NR sleeve for very abrasive control applications

 

 

 

 

To cover a wide range of applications, several rubber qualities are available:

Standard sleeve options

  • SBRT = Styrene butadiene Flowrox blend
  • EPDM = Ethylene propylene rubber

Other sleeve options

  • CR = Chloroprene rubber
  • CSM = Clorosulphonated polyethylene rubber
  • EPDMB = Ethylene propylene rubber Flowrox blend
  • HNBR = Hydrogenated nitrile rubber
  • IIR = Butyl rubber
  • NBR = Nitrile rubber
  • NBRF = Nitrile rubber, food quality (white inner lining)
  • NR = Natural rubber
  • NRF = Natural rubber, food quality (white inner lining)
  • SBRT/PU = Styrene butadiene with polyurethane inner lining

Sleeves for knife gate valves

The sleeve is a moulded part with a reinforcement steel ring integrated near the sealing area. The flange of the sleeve is reinforced with a load distribution ring to ensure even compression.

Ring sleeve material alternatives:

  • NR = Natural rubber
  • EPDM = Ethylene propylene rubber
  • NBR = Nitrile rubber

Elastomer sleeves on both sides of the gate provide a tight shut off.

Flowrox™ heavy duty pinch valves

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.

Flowrox™ PVG and PVEG pinch valves

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 involv...

Flowrox™ slurry knife gate valves

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 ...
