Cowan CGO Series Gas/Oil Rotary Actuators have Electronic Line Break Protection
Cowan CGO Series Gas/Oil Actuators uses natural gas or nitrogen gas as the motive power and hydraulic oil as the driving medium to actuate the pipeline valve to a fully open or fully closed position.
Features
- Electronic Line Break Protection
- Torques up to 4,000,000 in-lb
- SIL 2 Capable
Specifications
- Explosion-Proof Level: Ex d IIB T4
- Ingress Protection Level: IP 65 (IP 68 available)
- Suitable for Rotary (Quarter-Turn) valves. Linear design also available.
- Air Supply Pressure: 5 – 150 Bar
- Nitrogen Gas Application: High-sulfur natural gas and oil pipelines can use nitrogen gas as a power supply. With the bubble tight pneumatic control manifold, the nitrogen bottles only need to be replaced once or twice a year.
Valve Compatibility
Our Series CGO Gas/Oil Rotary Actuator is compatible with any process valve that requires rotary motion.
