Dependable, efficient and economical, the Flowserve 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.

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.

Operation of quarter-turn valves used in water and wastewater treatment, petroleum refining and distribution, and other industries.

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.
