Rotork, with numerous global locations and many offices also throughout the Americas, recently introduced a line break detection solution for remote pipeline or wellhead valves and critical process applications, where mains electricity or fluid power sources are not available or unreliable.
The failsafe actuator can be linear or quarter-turn, fail open or close, with cylinder operating pressure up to 3,000 psi (pounds per square inch). The Pressure Safe® hydraulic control system provides Emergency Shutdown (ESD) protection by automatically exhausting spring-return actuator pressure when pipeline pressure exceeds a high or low level set-point. It has a 3-way high and low pressure pilot valve which will trip the control system when line pressure is outside of the normal operating range.
