The Limitorque Direct Gas powered scotch yoke actuator series LDG is specifically designed to be operated by high pressure natural gas, or any other high pressure pneumatic fluid up to a maximum of 105 barg (1500 psig). LDG actuators are ideal for pipeline applications where no external sources of motive power are present and provide a robust heavy duty design and long service life with industry leading maintenace intervals. This makes them the actuator of choice for installation in remote or unmanned facilities.
The Limitorque Hydraulic Scotch Yoke actuator series LHS and LHH are designed to meet or exceed the most current and stringent safety and reliability standards for application in the oil and gas industry. LHS and LHH are ideal where hydraulic motive power is preferred for the operation of quarter-turn valves and for applications requiring a robust heavy duty design, long service life, high-torque and high-speed operation.
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.
The Valtek NR diaphragm actuator is a compact actuator with high torque and pneumatic stiffness for excellent throttling capabilities. The splined shaft connection eliminates backlash for precise control. Designed for supply air pressures to 80 psi (6 Bar). The high stiffness and rolling diaphragm provides firm control from 0 to 90 degrees.
The Valtek VR rotary cylinder actuator is a high pressure, compact actuator with high torque and pneumatic stiffness for excellent throttling capabilities. The standard splined shaft connection eliminates backlash for precise control. Designed for supply air pressures to 150 psi (10.3 Bar) to eliminate the need for a pressure regulator. The high stiffness provides firm control from 0 to 90 degrees.
