Designs
from RF Technologies, Inc., solve problems inherent with On/Off or
throttling control of abrasive, scaling, corrosive, slurries, sludge,
liquids and powders across a wide range of service parameters:
Temperature: -45ºC/-50ºF
to 148ºC/300ºF
Pressure: 0-600 psi/42 bar
PH 1-13
Throttling DP < 50 psi/3.4 bar
Valve Problems
RF VALVE
® & aiRFlex®
Solutions
Conventional Pinch
Excessive stretching of the rubber sleeve or diaphragm causes more
highly
accelerated wear under abrasive, erosive, or high temperature and pressure
conditions. Conventional pinch valves are not manufactured to standard ASME/ANSI or DIN face-to-face dimensions.
RF Solution
Non-stretch, high strength tube construction provides longer life &
reliability in abrasive, erosive, corrosive or high temperature, pressure
conditions. Full line of standard ASME/ANSI face-to-face dimensioned
valves, providing interchangeability NOT offered by other pinch valve
designs.
Ball, Plug, Gate, Butterfly, and Globe
Abrasive wear, scaling, or corrosion of rotating metal, lined surfaces,
seats and seals, cause valves to jam, seize, or leak; average maintenance
costs 30-70% of valve cost.
RF Solution
Elastomeric resistance to abrasive, corrosive media and self cleaning
action of high strength, seamless tube provides longer life and
reliability than other valves; average maintenance costs of 10-20% of
valve cost.
All Valves
Difficulty in predicting and assuring reliable valve operation and shut
off in abrasive, scaling, corrosive or plugging services. Higher
maintenance and inventory costs associated with multiple wear components
and more complicated valve designs.
RF Solution
The elastomer tube is the only component in contact with the process
stream minimizing repair costs. SMART Valve™ tube wear sensor provides
preventive maintenance alert and eliminates the cost of "throw-away
valves". Tube can be changed in-line for maximum efficiency.
High
performance analog and digital modulating valves are configured with
precision products from industry leaders like Fisher-Rosemount, ABB/Bailey,
Posi-Flex, Neles, Valtek, PMV, EIM, Auma, Rotork, Bernard and Limitorque,
to provide the highest level of accuracy and process control available
with full- and reduced-port trim designs.
