RF
Technologies
offers a full
line of manual and
automatic on/off control valves
with mechanical and air-actuated designs...
...featuring working
pressures up to 600 psi/40 bar...
...and
built to Industry Standard ASME/ANSI B16.1, DIN 3202 F5/F15 and ISO 5752
face-to-face dimensions, allowing interchangeability with most ball,
plug, diaphragm and gate valves.
What
differentiates all RF Valves from their competitors is their patented
non-stretch tube design featuring two joint-like expansion arches that
flex instead of stretching when closing. This feature also permits
standard ASME/ANSI B16.1, DIN 3202 F5/15 and ISO 5752 face-to-face
designs, and contributes to RF Valves' remarkable wear/higher cycle life
over conventional pinch, metal, or lined valve types.
Since the elastomer does not need to be stretched to
close the
valve, the tube is stiffer and stronger than conventional pinch
valves; this, combined with the expansion-joint-like arches,
makes the tube more stable under low or fluctuating line
pressures — and
even vacuum conditions!
Full-port and reduced-port tubes permit precise throttling control.
RF
tubes are available in a wide range of high-pressure, wear-resistant elastomers that outperform more expensive 316, stellite, or alloy ball,
plug, globe, diaphragm and conventional pinch valves in abrasive,
scaling or corrosive services. KEVLAR® reinforcing cords add unsurpassed
performance under high loads. Our VITON®- and TEFLON®-lined tubes
withstand even the most chemically aggressive and corrosive process
conditions.
A SMART
ValveTM
Wear-Monitoring Sensor wire is imbedded
between the reinforcing cords and wear rubber to alert
maintenance personnel that the tube needs replacement.
The
self-cleaning, flexing action of the elastomer tube prevents
build-up of scaling deposits and thus guarantees that the valve will not
seize or jam, even with high solids.
In-line
tube-change capability saves maintenance time
and eliminates the need for recalibration.
Zero-leakage shut-off, seamless flange-to-flange tube
construction, and sealed body design eliminate the need for
valve stems, packings, or seals that can leak.
