Flowrox™ valves
We provide pinch and slurry knife gate valves for flow control. Flowrox™ pinch valves can be either used for shut-off (also known as isolation) or control. Every Flowrox valve is fit for the most demanding applications in which conventional ones encounter problems with wear due to increased turbulence. When the controlled flow is abrasive, it is a big advantage to have only one, wear-resistant, valve part in contact with the medium. The need for maintenance and spare parts is reduced. We provide tailor-made valves for flow control solutions precisely according to given specifications.

Flowrox™ PVG and PVEG pinch valves |
|
Flowrox™ slurry knife gate 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 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. |
|
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. |
