Worm gear operators
Flowserve Corp. has added 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 waste water treatment. The new additions, the PT-12 and PT-14, are constructed with rugged, weatherproof, cast-iron housings for submersible or buried service applications. The Limitorque PT is optimized for motorized valve operation and is the first device on the market specifically designed for that function.
