Cort Systems & Actuators

Cort Systems

Cort supplies a range of complete valve control systems, including Emergency Shutdown Systems (ESD’s):-

In conjunction with the major oil and gas producers, we have also developed packages which provide line protection under abnormal operating conditions, including:

  • Solar Powered Pipeline Emergency Shutdown System – used to enable emergency shutdowns in pipelines where no conventional power source is available.
  • The Flowline Emergency Shutdown System – A simple and economical method of isolating a well installation in the event of abnormally high or low flowline pressure, especially in remote locations where no electricity or instrument air is available.
  • Pressure Protection System (PPS) – A trunnion mounted pipeline ball valve, complete with Scotch Yoke actuator and control system supplied in a self-contained and compact unit designed to protect equipment downstream of a pressure reducing station in a gas distribution system.

Scotch Yoke Actuators

Cort actuators are scotch yoke quarter turn design, with torque outputs from 5423 Nm to 73214 Nm. These actuators can be operated by instrument air, hydraulic fluid or line gas. Remote and local control can also be provided. Manual over-ride is available for emergency operation.

Description

VALVE OPERATION

CORT valves supply a complete engineered package of valve and operating equipment to provide any means of operation, such as:-

Manual

Wrench, multi-turn gearbox, quarter-turn gearbox or hand pump. Locks may be fitted to prevent unauthorised operation. Interlocks are used where sequential operation is specified.

Automatic

The operation is under control of a computer, PLC or devices such as fire or pipeline leakage detectors. For fail-safe systems it is normal to protect against power failure by storing sufficient energy for valve operation.

Powered

Any pneumatic, hydraulic or electric actuator may be specified. A powerpack is often provided to convert the energy source available on site into the form most suitable to operate the valve.

Remote

Any remote operating system and protocols may be specified.
