Rotork Skilmatic SI3 electro-hydraulic valve actuators deliver all-electric simplicity with precise hydraulic actuation for reliable mechanical failsafe operation. They represent the third generation of Rotork Skilmatic actuators, which are designed to provide safety-related emergency shutdown (ESD) and remotely operated shutoff valve (ROSoV) duties in challenging environments.
Skilmatic SI3 actuators offer a wide choice of operating speeds, additional ESD options with single or dual inputs, and enhancements to partial stroking to meet a wide variety of demanding applications. They incorporate an advanced control and monitoring system based on proven Rotork IQ3 intelligent electric actuator technology and provide advanced communication and data logging capabilities, enabling end-users to easily access important valve-related data in both the field and in the control room.

Flowserve Corporation announces the launch of the Limitorque Pneumatic Compact (LPC) Scotch yoke actuator. The LPC joins the growing family of technically advanced, fluid-powered actuators under the Limitorque brand that began expanding its portfolio beyond electric actuation earlier this year.
Complementary to the Limitorque Pneumatic Scotch yoke (LPS) model, the LPC applies similar design philosophy as the LPS for long operational life and reliability, but in a more compact, lower-cost package. The LPC has been designed with an industry-leading, 25-year design life, depending on service conditions, proper installation, operation and maintenance. In-field maintenance is required every five years for most applications, or as prescribed in EN 15714 for high-cycle applications.

Curtiss-Wright Corporation announced the expansion of its Exlar FT Series™ universal electric rod style linear actuator product line with the release of the FT45 model.
The FT Series roller screw driven actuators offer high thrust, high speed, and high robustness in a compact form factor, making them an ideal alternative to hydraulic cylinders. With continuous force rating to 40,000 lbf (178 kN), speed to 60 in/sec (1,500mm/sec) and stroke lengths from 6 inches (150mm) to 8 feet (2,400mm) the FT Series can be applied across a wide range of linear motion applications.
The new FT45 has a continuous force rating of 10,000 lbf (44.5 kN), filling the gap between the existing FT35 and FT60 models.

Emerson Process Management has added a new electro-hydraulic operator with the release of the Bettis EHO actuator. The EHO actuator is ideal for a diverse range of applications, from topsides valve automation on offshore platforms to remote pipelines where operational upsets can cause safety and environmental hazards, as well as costly production losses.
The EHO is available in either spring-return or double-acting configurations. Torque outputs can handle valve sizes from 6” to 60”. The EHO operates on utility electrical power or optional solar power for remote areas where electric power is not available or not reliable. The EHO is operable in temperatures ranging from -40°F to +140°F (-40°C to +60°C). Its fail safe capability is reliable with fast close or open stroke times, suitable for emergency shutdown in oil or gas service.

The new Kinetrol model 15 actuator bridges the large torque output difference between the model 14 and 16 actuators, consumes almost 30% less air per stroke than the model 16 actuator, is internally ported for NAMUR solenoid valve mounting, and allows direct mounting of Kinetrol positioners and switches.
“It’s exciting when a new product reduces costs, increases competitiveness and improves efficiency for customers,” says Greg Mitchell, General Manager Kinetrol USA.
