Actuators control
PNEUMOIDRAULICA ENGINEERING designs, manufactures and installs many kinds of actuator control systems, pneumatic or hydraulic, for the normal operation and the safety of the plants in Oil & Gas field. Those systems are equipped with electric, pneumatic and hydraulic circuits suitable for the control of the actuators moving the relevant valves. The control can be of on/off type (open/close) or proportional based on the signal received from the control room (pneumatic or electric). It is also available a system with “Partial Stroke” test device, manual or automatic, for application in HIPPS systems.
Standard features:
- Components layout carefully studied to facilitate the control, checking and maintenance operations
- Executions in AISI316 stainless steel (even varnished)
- Arrangement in cabinet IP55 or on plate at sight
- Maximum pressure 420 bar (6,000 PSI)
- Double ferrule compression fittings
- Imperial or Inch Tubing (according to ASTM A-269)
- Hydro-pneumatic accumulators (bladder-type or piston) or pneumatic tanks to ensure emergency manoeuvres even in case of main power failure
- Local and remote control via interface with PCL / DCS / SCADA / RTU
- EEx-ia / EEx-d executions
