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

Standard Positioners
Flowrox control valve actuator is equipped with a positioner. The standard positioners for various actuators are as follows:

For Pneumatic Actuators
Electro-pneumatic (AK), input signal 4 - 20mA Pneumatic (AN), input signal 0.2 - 1 bar

For Hydraulic Actuators
Electro-hydraulic (HP), input signal 4 - 20mA

For Electric Actuator
Electronic (EO), input signal 4 - 20mA

Flowrox control valve sizing is based on IEC60534 standard (harmonized with ANSI/ISA S75 standards). The valve flow coefficient Cv defines the control valve flow capacity i.e. the valve size (diameter).
