Valtek Spring Cylinder Linear Actuators, Pneumatic Actuators – Linear – VL Series | Flowserve, Valtek Spring Cylinder Linear Actuators, Valtek Spring Cylinder Linear Actuators, 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.
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. Offered in.
Valtek VL series spring cylinder linear actuators are powerful, compact, high-performance pneumatic actuators that provide solid throttling or on-off operation for automatic control valves. The positioner supplies air to both sides of the piston, providing stiff, precise movement and high-frequency response and quick stroke speeds.
