George Fisher's New Type 546 Ball Valve Features Safer, Robust Design in Compact Overall Length

TUSTIN, Calif. - May 06, 2003- George Fischer, Inc. has added the Type 546 Ball Valve to its extensive line of manual and actuated valves. The new valve features a short overall length, buttress thread design and universal multi-function module. These features combine to provide the true union ball valve with added safety and functionality for a diverse range of applications. Available in PVC and CPVC, with future releases in PP and PVDF, the Type 546 Ball Valve is ideally suited for water and wastewater treatment and chemical processing applications.

The valve nut's buttress thread design, specifically selected for its high performance characteristics, offers robust construction and provides a stronger connection to piping systems for added safety. The short overall length, more than 9% shorter than the previous generation Type 346 Valve, allows for
design of more compact systems for space-saving economies in plant construction.

Other outstanding new features include the valve's multi-function module. This module significantly expands the number of uses for the Type 546 by allowing the user to easily add different accessories, actuators and switches. The multi-function module can also be used for easy wall/panel installation or as a position feedback unit by adding one of five different micro-switch options.

The Type 546 Ball Valve also includes a newly designed ratchet styled handle which prevents accidental movement for safer operation. A lockable handle and blow-out proof stem with an intended break point are other important added safety features. The valve is available in sizes 3/8" - 2" (16mm - 63mm) with choice of red or black handle.

As part of the new valve introduction, George Fischer is also introducing a new generation of pneumatic and electric actuators that have been designed specifically to complement the modularity
and flexibility of the 546 Valve and provide a system approach to piping system design. These actuators easily mount on the standardized mechanical interface of the 546 Valve's multi-function module and offer a wide range of accessories, all-plastic housing, high protection rating, and a service life of 250,000 cycles. They also include a standard ISO-Namur connection for greater flexibility in adding accessories.

The new PA 11 and PA 21 Pneumatic Actuators incorporate a pre-loaded safety spring that provides easier maintenance and added operator safety, and are available in two sizes to closely match the torque requirements of the valve. The EA 11 and EA 21 Electric Actuators are CE, and CSA certified and are available for on/off or process control applications. Electric actuators include automatic adjustment of voltage and frequency and integrated manual override.

George Fischer offers a complete CAD product library with 2D and 3D data in all conventional formats to support efficient plant planning. The product configurator makes it easy to order the exact 546 Ball Valve to fit any application.

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.
