Metso Automation: New CINTAC™ Advanced Automation System simplifies and reduces the cost of automating rotary on-off valves.
 The new CINTAC system merges Jamesbury® actuator expertise with StoneL® advanced communication and control system technology and eliminates the need to engineer, procure and assemble separate rack and pinion actuators, switches, solenoid valves, linkages, tubes, and fittings.
The CINTAC Advanced Automation System has been designed as a cost-effective platform with field-proven components. Designed to support future growth, the system includes advanced diagnostics, digital bus communication capabilities and automated on-line emergency shutdown testing. Users benefit from intelligent reliability, plug and play installation, as well as many unique standard features that make the system easier to use, install and maintain.
The heart of the system is a rugged, field proven rack and pinion actuator with ISO 5211 interface for compatibility with any quarter turn valve. Position sensing is done by a contact-free magnetic resistive (Mag Res) sensor with no mechanical parts or connections to wear out or bind. It is not affected by lateral or vertical shaft movement. Push button switch setting allows for true contact-free position setting and eliminates having to set cams.
The unit is completely sealed and protected from corrosion and short-circuiting due to moisture. Its solid-state circuitry assures the longevity of switches. The unit accepts either AC or DC input voltage for easy adaptation to existing power and it eliminates the potential for burned-out electronics. An additional benefit of the universal power input is reduced inventory (one unit meets most power needs).
Leak-free integral air porting further improves the unit's reliability by eliminating crimping or bending of tubing, leaking fittings, and worn or broken hoses. A built-in spring-return re-breather automatically feeds clean instrument air to the spring housing to prevent water ingress and internal corrosion. The CINTAC™ systems construction allows all critical components to be easily accessible through a removable cover.
The CINTAC Advanced Automation System operates at temperatures ranging from -20°C to 65°C and pressures to 8.3 bars. Units with a low temperature option to -40º C are also available. The system is also available with the following approvals:
NEC (North America):
