Pneumatic Modulating Control Valves
Valve of Choice
Proven designs built to last under the toughest operating conditions, the RF Control Valve is the valve of choice for many of customers in the mining, power, industrial mineral, chemical, pulp and paper and wastewater industries.
RF Valve® is furnished with a pneumatic or electro-pneumatic positioner, operating with 4-20mA control and/or feedback signals. Brands include the most advanced digital controllers offered by Siemens, Fisher, PMV, Bailey, Valtek, Neles, and others compatible with HART, Foundation Fieldbus, and Profibus communication protocols.
Design Features
- Industry-standard face-to-face, making it interchange-able with most ball valves, plug valves, gate valves and diaphragm valves
- Patented elastomer tube technology that supplies a stronger and more robust construction, prevents stretching, and minimizes “flutter” from cavitation
- Split valve body design, combined with elastomer tubes that have no flange bolt holes, to allow in-line tube changes that dramatically reduce maintenance time
- Stainless steel pull bars and fasteners
- Pneumatic actuators with stainless steel shafts, tie rods and fasteners
- Exterior as well as interior corrosion-resistant coating
