George Fischer Introduces Second Generation of 3-Way Actuated Ball Valves Featuring High Stability and Excellent Chemical Resistance in Compact Design



TUSTIN, Calif. - Oct.19, 2005 - George Fischer, Inc. introduces a new generation of 3-way actuated ball valves with the Electrically Actuated Ball Valve Series Type 175/176/177/178 and the Pneumatically Actuated Ball Valve Series Type 275/276/277/278. Offering high stability and excellent flow characteristics, these valves incorporate all the inherent advantages offered with the new EA 21 electric actuator and PA21 pneumatic actuator.

With the new actuators designed with housings made of PP-GV 30 for high chemical resistance, these actuated valves are especially well suited for aggressive fluids and the heavy-duty requirements of harsh industrial applications. Typical 3-way ball valve applications include diverting and mixing liquids in piping systems for such industries as food and chemical processing.

Both of the new 3-way actuated ball valve series are available in a PVC, CPVC, PP, and SYGEF®-PVDF in sizes from ½" - 2" (20mm - 63mm) with EPDM and FPM seals. Features include a 250,000 actuator cycle life for long, maintenance-free service, and compact, modular design for space savings and flexibility. The L-port version provides independent connection of inlets with outlets, while the T-port version provides straight through flow, independent connections of inlets with outlets, or interconnections of all three ports. A variety of accessories are available from position feedback to control capabilities.

The Electrically Actuated Ball Valve Types 175/176/177/178 feature a vertical (Type 178) or horizontal (Types 175, 176, and 177) configuration. The 175/176/177/178 valves incorporate the EA 21 actuator, which comes equipped with integrated emergency manual override and automatic adjustment of voltage and frequency used for on/off or process control applications. The patented manual override for these units is fully integrated into the actuator, allowing for the voltage to be interrupted and the valve manually actuated when a situation warrants. A variety of modular assemblies are available to custom-fit the valve to the application, providing high flexibility in design and operation for an optimal cost-effective solution. The EA 21 is CE and CSA certified, with UL approval pending and is available with universal automatic voltage adjustment of 100/20 VAC or a 24 AC/DC power module. Options include a cycle monitoring feature for added safety and a positioner for increased accuracy and process-safety.

The Pneumatically Actuated Ball Valve Types 275/276/277/278 feature a vertical (Type 278) or horizontal (Types 275, 276, 277) configuration, option for manual override, optional stroke limiter for accurate adjustment of the valve stop, and an ISO/NAUMR connection interface, which provides greater flexibility in adding accessories. This series is also available with extra limit switches and 1000 ohm potentiometer for position feedback.

The George Fischer, Inc. product offering includes a full range of plastic pipe, fittings, tubing, valves, actuators, rotameters, fusion machines, secondary containment, tank linings, heat exchangers, custom products, and sensors and instrumentation for industrial process control.
