Terminator Yoke Mount General Description

The Terminator valve actuator with Gemini controller is an economical emergency chlorine shutoff system designed for use on chlorine and sulfur dioxide ton containers (one tonne drums) 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 when a CGA820 connection is being used. Adapters are available to allow the Terminator to work alongside most tank mounted vacuum regulators. As a safety device, the Terminator is only powered in the closing direction. After process connections are made, leak tested, and the valve opened, the Terminator is then securely attached to the yoke or valve with a few simple turns of a hand knob.

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 container valve is rapidly closed. One or two Terminator actuators can be controlled by the Gemini, and systems can be interconnected to protect larger, manifolded banks of chlorine ton containers. The Gemini includes a normally open, low voltage, momentary contact relay output for remote indication of emer-gency close activation. An optional Relay Interface Module (RIM) adds three dry contact relay outputs rated for 5 A @ 250 V with N.O./N.C. and latching capability.

Features:

• Economical, low cost solution.
• Protects personnel and community by quickly and automatically stopping a gas leak.
• Easy-to-use clamp mount design for ton containers.
• Battery powered system - continues to protect for up to 5 days if AC power lost.
• Fire code approved for many applications as scrubber alternative.
• Helps comply with RMP gas leak mitigation requirement.
• Compatible with most tank mounted vacuum regulators.
