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.
Simple to install and service
Face-to-face according to industry standards. Contains only two service parts; ring sleeves and gland packing.
The SKW valves are available in sizes DN50–600.
Slurry flanged knife gate valves (SKF) are equipped with flanges. They isolate the flow even in the most demanding process conditions. They contain only two service parts: ring sleeves and a secondary seal.
The SKF valves are available in sizes DN80-600.
We have repositioned actuator cylinders to the side in bigger slurry knife gate valves over DN 900. The benefits are:
Available in sizes from DN 900 to DN 1500. They can handle pressures from 10 and down to 4 bar, depending on the size. Flange drillings PN10 or ANSI 150, others on request. The actuator can be either hydraulic or electric.
Flowrox slurry knife gate valve body for sizes DN 900 – DN 1500 is entirely cast in one piece. This means there are no risks for leaking through the body. The new valve construction is simpler and more robust. Fewer parts also mean savings in spare part inventory and maintenance time.
Slurry knife gate valve (SKH) is designed for higher pressures (up to 20 bar) in heavy duty purposes to isolate the flow. Just as previously presented SKW and SKF valves, SKH valves also contain only two service parts: ring sleeves and gland packing.
The SKH valves are available in sizes DN80–600.
Tower design fits well with smaller knife gate valves.
Flowrox SKF knife gate valves DN 900–1500 use a new approach. Instead of tower design, two actuator cylinders are positioned to the sides.
Actuator cylinders have been repositioned to the side in bigger slurry knife gate valves over DN 900.

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™ 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.
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.
