Operation

AMOT 1476 series Safety Controls are used primarily for equipment shutdown in emergencies, or for initiating control sequences. When they are applied in combination with many AMOT sensing valves and accessories, they provide positive and reliable protection against low or high pressure, temperature, excessive vibration, high or low speed, and other undesirable conditions. For quick, visual pin-pointing of trouble, Model 2400 Mechanical Indicating relays are used with the 1476 controls.

The 1476 series is also widely adaptable to automatically sequenced or remotely operated control systems. The 1476 consists of a valve or lever which is controlled by a tripping mechanism which responds to loss of pressure. When the sensed pressure drops below the set point, the mechanism trips and snaps the valve closed.

Model 1476 systems are fail safe! Loss of control pressure through leaks or broken tubing will act to trip the safety control without the use of external power sources.
