Terminator™ Chlorine Gas Valve Actuator

The Terminator™ Actuator is an economical safety device that automatically closes a chlorine cylinder or ton container valve in case of a leak or emergency. The Terminator is easily installed on either cylinders or ton containers that use standard USA style chlorine valves. The Terminator is a DC powered impact device that provides 40 to 50 ft-lbs of emergency closing torque as recommended by the Chlorine Institute. The Terminator is installed after process connections are made and the valve is opened. The Terminator actuator uses the Gemini Controller to provide power and logic to the actuator. The Gemini is a 2-channel controller with an integral 12V battery that provides main and backup power. If AC charging power is interrupted and not restored within 3 to 5 days, the Gemini will eventually initiate an emergency close to protect against an unguarded gas system. The Gemini provides a remote activation input for panic switches, gas detectors or activation via SCADA and also offers a relay output that indicates when an emergency close operation has been performed.

The Terminator is available in two different mounting configurations:

Gravity Mount — For 150lb (68 kg) Cylinders DOWNLOAD DATASHEET
The original parallel rod mount is simple to install on a vertical style cylinder. Its design places the drive bushing directly on the valve stem with two parallel rods extending down along the valve body. Once installed, a simple retention pin is placed through the bottom of the parallel rods for added security. The parallel rod design is compatible with all cylinder mounted vacuum regulators and with the standard CGA 820 style yoke that is used when feeding under pressure. No special adapters or tools are required for installation with any of these devices.


Yoke Clamp Mount — For Ton Containers DOWNLOAD DATASHEET
The new yoke clamp mount Terminator incorporates the same clamping mechanism as on our Eclipse Actuator. Two clamp arms secure the Terminator to a standard CGA820 style yoke by simply tightening a hand knob. For installations where the ton container has a vacuum regulator mounted directly to it, an auxiliary valve adapter or vacuum regulator extension provides clearance so the Terminator and vacuum regulator can both be mounted to the tank valve.
