The "Skilmatic SI Range" combines the ease of electrical operation with the accuracy of hydraulic control, as well as the reliability of fail-safe operation through mechanical spring return or accumulators. Designed for safety instrumented systems (SIS) to protect human life, the environment, and process plants, it provides a reliable means to secure a safe position in the event of power loss, ESD, or control signal loss. Additionally, independent limit switches and position feedback are provided, along with selectable status and alarm display for voltage-free relay output as standard. 【Advantages of the Third Generation Skilmatic (excerpt)】 ■ Fail-safe, close, open, or last position hold settings ■ Explosion-proof specifications ExdIIB/IIC T4 & waterproof performance IP66/68 ■ Data logger retains records of 3000 events ■ Operating temperature range from -50°C to +70°C ■ Usable with various power supplies including single-phase, three-phase, or DC 24V *For more details, please refer to the PDF document or feel free to contact us.

The "RC200" is a Scotch yoke pneumatic small actuator that, thanks to its unique Scotch yoke design, has a very small body while being able to output high torque at the end of the stroke. It is available in double-acting and spring return types, and a manual handle can also be supplied as an option. Compared to other rack and pinion actuators, it has a smaller stroke volume, which significantly contributes to saving air consumption. 【Features】 ■ On/off or modulating ■ Lightweight, compact design ■ Double-acting or spring return ■ Safe spring with pre-adjusted tension ■ High torque output at stroke termination *For more details, please refer to the PDF materials or feel free to contact us.

The "GT Range" is available in a wide range of body sizes in both double-acting and spring return configurations. The units can be easily exchanged from one to another even on-site. In addition to the standard 90° rotation, 120°, 180°, and 240° rotations are also available, and all models incorporate an anti-blowout design. We are currently distributing a comprehensive catalog for free. If you are interested, please feel free to download it. 【Features】 ■ 120°, 180°, and 240° rotations are also available ■ Double-acting and spring return body sizes ■ Many options available, etc. *For more details, please refer to the PDF materials or feel free to contact us.

The "SI Range" we handle combines the ease of electric operation with the precision of hydraulic control, as well as the reliability of spring return mechanisms and fail-safe operation of accumulators. We offer two types of models: one for 90° rotation and a linear type. The torque for the 90° rotation model ranges from 65 to 600,000 Nm (48 to 442,500 lbf.ft), while the thrust for the linear type ranges from 1.5 to 3,850 kN (340 to 865,500 lbf). Regarding the safety instrumentation system of Systematic Capability SC-3, we have obtained IEC 61508:2010 compliance certification, making it suitable for use in SIL2 and SIL3. 【Features】 ■ Selection of fail-safe operation during ESD signals or power loss ■ Current opening degree hold during power loss (optional) ■ Operable solely with power supply (single-phase, three-phase, 24VDC) ■ Explosion-proof area certification Ex d IIB or IIC ■ Waterproof protection rating: IP66 or 68 (control module), IP66 or 67 (main assembly) *For more details, please refer to the PDF materials or feel free to contact us.

The "GP/GH range" is designed for the operation of ball valves, butterfly valves, and plug valves that require a rotational motion with a swing angle of 90° for on-off or modulating purposes. These actuators have proven their robustness through use in thousands of diverse applications around the world. You can choose either a symmetrical yoke or an eccentric yoke. By adopting an eccentric yoke, the actuator achieves miniaturization, lightweight design, and cost reduction due to appropriate torque demand characteristics. 【Features】 ■ In the case of a spring return unit, it is possible to select the direction of operation. ■ The central body has a built-in pressure relief valve. ■ Output torque data for each opening degree. ■ The symmetrical yoke transmits maximum torque at both ends of the stroke. ■ The eccentric yoke transmits maximum torque at only one end of the stroke. *For more details, please refer to the PDF document or feel free to contact us.

The "CP Range" is a versatile modular Scotch yoke actuator, available in two configurations: double-acting and spring-return. It features a compact and efficient design that generates very high torque even at low pressure. By adopting the design concepts of our large actuators for harsh conditions, it provides the same level of quality as actuators designed for severe environments, despite being a small 90° rotation actuator. With the evolution of the product, we have been able to produce higher torque without compromising the robustness and reliability of the design, even with a smaller and lighter actuator. 【Features】 ■ Modular design allows for easy configuration changes to suit various applications ■ It is also possible to change only the spring used ■ The jack screw type manual handle can be easily attached at any time ■ Long lifespan with accurately positioned, well-balanced piston rod support bearings ■ Eliminates misalignment, high friction, and wear *For more details, please refer to the PDF document or feel free to contact us.
