DALLAS - April 28, 2005 - Flowserve Corp., a global provider of fluid motion and control products and services, announces the addition of two new sizes to the Flowserve Limitorque PT series of worm gear operators. The PT series is built to provide the torque needed for operation of quarter-turn valves used in water and wastewater treatment, petroleum refining and distribution, and other industries.The new additions to the PT series are the PT-12 and PT-14, rated at 880 ft-lb and 1,600 ft-lb respectively, designed to provide added versatility for torque and operating time requirements.
The new PT-12 and PT-14 models, like the larger worm gear operators in the PT product line, are constructed with a rugged cast-iron housing for weatherproof, submersible or buried service applications.Dependable, efficient and economical, the Limitorque PT is optimized for motorized valve operation and is the first such device on the market specifically designed for that function. While the PT can be used for manual valve operation, motorized valve control using the PT offers superior process control.Used in tandem with the industry-leading Limitorque MX, L120 or SMB electric actuators, the PT provides a dependable and cost-effective flow control solution for quarter-turn applications.
Available in a wide range of operational speeds and with output torques up to 135,000 ft-lb (183,050 N m), the PT delivers extraordinary valve control and consistent performance by combining common worm gear operator technology with a state-of-the-art design.Central to the design of the PT is its highly efficient one-piece rolled worm and shaft. Unnecessary parts have been eliminated to improve performance, and a careful evaluation of the operator's components has led to standardized parts across all torque ranges.
Optional spur gear attachments facilitate the economical use of smaller actuators with the PT.Available with ductile iron worm gears or bronze alloy worm gears for AWWA and modulating applications, the PT can be installed in the harshest environments, including low temperature applications to -50°C. When coupled with Flowserve Limitorque electric actuators, the PT will provide years of trouble-free service."
The addition of these two worm gear operators to the product line allows us to more effectively meet customer application requirements in the expanding market for smaller quarter-turn valves," says Dave Montgomery, product manager, Flowserve Flow Control, Limitorque Actuation Systems.About Flowserve Corp.Flowserve Corp. is one of the world's leading providers of fluid motion and control products and services.
