Terminator Gravity Mount General Description

The Terminator valve actuator with Gemini controller is an economical emergency chlorine shutoff system designed for use on 150 lb (68 kg) type chlorine and sulfur dioxide cylinders commonly used at water and wastewater treatment plants. The system is DC electric powered with AC only used for keeping battery optimally charged at all times. In the event of a loss of AC power, the system continues to protect for 24 hours. If AC power remains off for an extended period of time, the system will auto-initiate emergency close while sufficient battery power remains.

The Terminator is compatible with standard valves meeting Chlorine Institute specifications and requires no tools or adapters for installation. The Terminator is simply placed on the cylinder valve after process connections are made, leak tested, and the valve opened. Being a safety device, the Terminator is only powered in the closing direction. When the Gemini controller receives an emergency close signal from a gas detector, emergency shutoff switch, or other input, the Terminator is activated and the cylinder valve is rapidly closed. One or two Terminator actuators may be controlled by the Gemini, making this the perfect safety solution for both single and dual cylinder applications. System includes a low voltage 24VDC relay output for remote indication of emergency close activation and an optional relay in-terface module provides dry contact relays with latching capabilities when required.
