THE RF TECHNOLOGIES ALTERNATIVE

Pinch valves offer 100 percent unobstructed full-port flow. They provide a reliable alternative to a plug, ball, gate, or butterfly valve, which require valve-stem packing, bearings or rotating/rubbing components most commonly identified with leakage, failure and maintenance. For abrasive, scaling, corrosive or plugging-prone water, wastewater or chemical services, RF Valves provide unique and cost-effective alternatives to automated valves that customarily have difficulty in these services.

When considering RF Valve as the alternative, please be sure to note:

There is only one wetted part in contact with media — the elastomer tube
Efficient design eliminates 95% of components that are primary cause wear and maintenance in other valves
Preventive-maintenance alert technology is available
Simple split body assemble provides for in-line replacement of the elastomer tube

TECHNICAL ADVANTAGES

Standard full port design provides unobstructed, bi-directional flow, low resistance, zero leakage shut-off and precise, repeatable linear flow control.

The self-cleaning, flexing action of the pinch valve elastomer tubes prevents build-up of scaling deposits and thus guarantees that the valve will not jam or seize, even in high solids.
High pressure molded elastomer tube insert outperforms more expensive 316, stellite, or alloy ball, plug, globe, diaphragm and conventional pinch valves in abrasive, scaling or corrosive services.
Interchangeable with most standard ASME/ANSI B16.10 face-to-face dimensions common to many AWWA ball, plug, gate and diaphragm valves. Versatile retrofit valve for plant upgrade and modernization projects.
Elastomer tube is the only wear part in contact with process stream. Tube replacement, when required, is accomplished without complicated tools, components, or specialized skills; maintenance costs are reduced up to 70 percent.
Seamless flange-to-flange tube construction and sealed body design eliminates valve stem, packings, or seals that can leak.
