Flowserve Introduces New Models to PT Series Worm Gears

Share |

April 13, 2005—Flowserve Corp., a provider of fluid motion and control products and services, added two new sizes to the Flowserve Limitorque PT series for worm gear operations. 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 are PT-12 and PT-14, rated at 880 and 1,600 ft.-lbs. respectively, designed to provide versatility for torque and operating time requirements. The new models are constructed with a rugged cast-iron housing for weatherproof, submersible or buried service applications.

The Limitorque PT can be used for manual valve operation, motorized valve control using the PT offers superior process control.

Central to the design of the PT is a one-piece rolled worm and shaft. According to the company's press release, 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. Optimized spur gear attachments facilitate the use of smaller actuators with the PT.

The PT can be installed in environments with temperatures as low as ?50?C.
