Features of Gas-Over-Oil Actuator
The Gas Over Oil Actuator (GOA) is a robust control solution that utilizes natural gas or nitrogen as the motive power, coupled with hydraulic oil as the driving medium. This actuator is capable of modulating pipeline valves from a fully open to a fully closed position with precision.
1. Key Operational Features
Local Control Options: The GOA supports local pneumatic and hydraulic operation, providing versatile control mechanisms.
Automatic Line Break Protection: It includes an automatic line break protection feature to enhance safety and reliability.
Remote Control Capabilities: The actuator can be controlled remotely, offering flexibility in operation.
Emergency Shutdown (ESD): Equipped with an Emergency Shutdown system for quick response to critical situations.
2. Safety and Compliance
The GOA and its associated electromagnetic valve are designed to meet the stringent requirements of Safety Integrity Levels ISL2(1001) and SIL3(1002), ensuring high levels of safety and reliability.
3. Scotch-Yoke Mechanism
The actuator features a Scotch-Yoke mechanism that allows for adjustments in the open and closed positions by ±5 degrees. This capability helps to eliminate system errors and ensures accurate valve positioning.
The design of the Scotch-Yoke mechanism facilitates easier maintenance, contributing to the continuous operation of the valve.
