Halogen Valve Systems’ Terminator Actuator™ closes 150 lb. toxic gas cylinder valves in three seconds when activated from remote sensors and switches. This fire code approved, microprocessor-controlled system has a self-contained battery that guarantees operation of the motorized closing mechanism during a power failure. A computer system monitors the battery, regulates the charger and closes the system automatically if a low battery situation occurs. The actuator applies 40 foot-pounds of torque during an emergency activation to insure the gas valve closes.

The ChloroSense™ reagent free portable chlorine monitor from Palintest does not depend on the user’s technique, allowing untrained personnel to produce accurate chlorine results on the first test. Once the sample is collected and inserted into the instrument, the test becomes automated and provides results in less than one minute. The instrument then records and stores all chlorine analysis plus temperature results in memory, and the data can be reviewed on the display or exported to a PC via a waterproof USB port. The instrument’s automated testing ranges, from 0-10 mg/l Cl to 0-100 mg/l Cl, are ideal for both municipal water monitoring and water main rehabilitation.

Robo-Control® provides actuators to open and close chlorine container valves. Digital indication of valve position and outputs for valve position are available. The actuator will communicate with an RTU or PLC for SCADA or in-plant control. Integral leak detectors provide immediate closure when a leak is detected. The actuators are battery operated and mount to the valve without interfering with existing hardware. When a chlorine system has actuators and a scrubber, scrubber size can be limited to one container since all containers will be closed if a leak occurs.
