The Flowserve VL-C spring cylinder linear actuators are powerful, compact, high-performance pneumatic actuators that provide solid throttling or on-off operation for automatic control valves. For applications where aluminum materials are not acceptable, Flowserve offers the compact, lightweight and high thrust of the VL-C carbon steel spring cylinder linear actuator. Offering identical springs and all the advantages of VL actuators, the VL-C actuator replaces all aluminum parts with carbon steel.
For applications where ultra-high cycle (UHC) life is needed, Flowserve offers the exceptionally long cycle life of the VL-UHC series actuators. By adding and modifying several parts used in the standard VL series actuator, the VL-UHC gains a cycle life previously thought unattainable. The VL-UHC actuator is particularly well suited for applications where high numbers of full stroke cycles are required.
