Control panel

The pneumatic/hydraulic hybrid control panel is of an integrated type that uses the local gas supply to drive the hydraulic pump to deliver hydraulic pressure to the sub-surface safety valve. The gas supply is also used as a medium to control the surface safety valve. Charging/discharging of control pneumatic/hydraulic pressure logically opens/closes the valve, in order to ensure safe production and protection of the X-tree. Main parts: Gas-filtering system, PSH/PSL pilot valves, relay valve, quick-exhaust valve, flame arrestor, pressure regulator, filtering pressure gauge, fusible plug, time-delay valve, volume bottle, and SS fitting and tubing. Power Supply Nitrogen gas, compressed air or purified natural gas Control Objects Sub-surface safety valve, master safety valve, wing safety valve Applicable Service Conditions According to customer's need Features 1. The sub-surface safety valve is controlled by hydraulic pressure, and the surface safety valve by pneumatic pressure. 2. Suitable for complex geological conditions with extensive control distances. 3. Components and units are manufactured from corrosion-resistant SS. 4. Optional: temperature/pressure data acquisition, remote-control solenoid valves, RTU unit and SCADA functions.
