Toxic Gas Multi-Actuator Valve Controller
The Duplex Model II control system quickly closes up to two Eclipse actuators on toxic gas cylinder and ton container valves when activated by panic buttons or remote gas sensors. The Duplex Model II computer system applies 30 foot-pounds of torque for test closures and 50 foot-pounds of torque for emergency closures of the cylinder valve. All Fire Codes recognize and approve the “automatic-closing fail-safe shutoff valve” system in lieu of a scrubber treatment system. With a Duplex model II, SCADA systems can be provided with actuator closure status and error codes to quickly analyze problems and take the appropriate corrective action.
