The uniqueness of RF valves:

The new, patented tube is preshaped and is not stretched when closing but folded shut. This means tension in the material is no longer a problem and the durability is greatly extended. Much thicker tubes can be used thereby increasing the operational periods considerably (up to 10 times).
The assembly dimensions are according to the DIN and ANSI standards, and mean a trouble-free assembly and no need to adapt your pipework.
RF valves are very easy to dismantle and to recondition. You only remove the bottom casing, put in a new tube and it's finished (no calibration required).
The unique design is suitable for many types of tube material, also for higher temperatures.

"PROBLEM KILLER" Revolution from USA
We are delighted to announce that RF Tek (USA/Finland) has appointed Conovalve as their official agent/distributor for Belgium and the Netherlands. RF valves are the latest development in valve technology. They are a revolutionary and patented design on the basis of the well-known pinch valve; they maintain all the advantages of pinch valves whilst making the disadvantages a thing of the past.

These ultimate "problem killers" can be supplied quickly in two basic types: the economic AiRFlex, where your instrument air in the body provides the driving force, and the advanced RF Valve, which is suitable for higher pressures. Both types can be supplied as a shut-off valve or as a control valve.
