Product Description: ROTORK Remote Control Pneumatic ActuatorRC210-DARC220-DARC230-DARC240-DARC250-DARC260-DARC265-DARC270-DARC280-DAThe ROTORK Remote Control pneumatic actuator adopts a modern yoke-type mechanical structure, providing high breakaway and end-of-travel torque in an extremely compact design. It is available in double-acting or spring-return versions, both of which can be equipped with an integrated manual override. The spring-return actuator features an epoxy-coated spring housed within an anodized enclosure. Guided by three high-performance material bearings on the piston, it ensures precise coaxial alignment, long sealing cycles, and smooth, stable operation. Compared to other actuators with the same torque output, the RC200 actuator is lighter and more compact. This results in a tight, lightweight, yet robust and stable valve/actuator combination, especially when a manual override is required. Additionally, the RC200 series consumes less air compared to rack-and-pinion actuators, significantly reducing compressed air usage. QualityThe manufacturing of RC200 actuators strictly complies with ISO 9001/14000 standards. The products meet all international standards and carry the CE mark in accordance with PED and ATEX. We consistently use high-quality materials and ensure rigorous design and production processes, guaranteeing that our actuators remain durable and reliable over long life cycles. As a leader in valve actuator technology, we offer a comprehensive range of valve actuators, control accessories, and related equipment. We also provide various services related to valve actuators, including commissioning, preventive maintenance, and upgrade solutions. Rotork specializes in providing fluid power actuators and control systems, along with comprehensive support. We are committed to delivering the latest technology to the market while maintaining high product quality, innovative design, excellent reliability, and outstanding performance. We continuously invest in and develop our technical team, including engineering applications, product improvements, and new product research and development. This ensures that our customers benefit from the advantages of advanced technology and that our efforts align with user needs. Most importantly, we remain steadfast in our commitment to meeting the specific requirements of various applications, including oil and gas extraction and transportation, urban water supply and wastewater treatment, power generation equipment, and chemical and process industries. With over 60 years of design and manufacturing experience, we have thousands of successful valve actuator applications worldwide. EfficiencyUnlike the rack-and-pinion actuators offered by our competitors, the RC200 features a yoke-type design. This design increases torque output by 50% at the end of the stroke, which is precisely where valves need it most. ReliabilityEvery Rotork actuator delivers long, effective service life with minimal maintenance. more>
