Model HSRA-2 Hydraulic Actuator
Like the Model RA-ESD (Emergency Shutdown System) Actuator, the Model HSRA-2 Hydraulic Self-Contained ESD System is designed to provide immediate shutdown of a well or pipeline even in the most remote locations. The major difference is that this actuator has been designed specifically for 2-1/16" 2,000 to 5,000 psi applications. As a result, the actuator design is smaller, lighter and more compact than any comparable actuator on the market. This compact system consists of a streamlined reduced volume hydraulic actuator, a pump module, and a sensing pilot.
Features –
- Totally manual and requires no external power source - no electricity, no pipeline pressurized gas, no nitrogen gas bottles, etc. - to operate
- Completely self-contained to prevent contaminants from entering and causing internal corrosion that could damage the system
- Two distinct pressures from a single pump module: high pressure for the actuator circuit and low pressure for the control circuit
- High spring pre-load ensures enough force to close the gate valve at zero flowline pressures
- Reduced volume minimizes closing time
