Flowrox Control Valves

Flowrox control valves are designed for demanding control applications in which conventional valves encounter problems with wear and turbulence. Controllability can be further improved with conical sleeves or smart positioners. Elastic sleeves have been applied for improved wear resistance.

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.


Sizing and selecting the control valve

Control valve sizing and selection is a result from process conditions. Namely, flow rate range, slurry specific gravity (s.g.) and pressure difference over the valve define how the control valve is sized and selected. Flowrox control valve sizing is based on international IEC60534 standard (harmonized with ANSI/ISA S75 standards).

The optimal control range of the Flowrox valve is between 10-50 % of opening. Flowrox offers accurate control and the longest service life time in the most demanding slurries.

Flowrox Oy was the first pinch valve manufacturer in the world to get awarded the ISO9001:2000 Quality Certificate in 1997. Flowrox valves also meet the ANSI/ISA Pinch valve standard ANSI/ISA 75.10.02.
