The AT03069 Murphymatic® Engine Throttle Controller is a completely reliable heavy duty device developed specifically to automatically control engine speed to meet system demand. Low current, high torque, solid state switching and electronic clutch make it ideal for all automatic and semiautomatic engine systems.

Used with the appropriate Murphy Swichgage®, near constant pressure, level, and load can be maintained. Common applications include controlling pressure in City water and irrigation systems; controlling level in water or oil storage tanks, sewer disposal systems and flood control basins; controlling temperature in multi engine cooling systems and air conditioning systems; and controlling engine load depending upon external conditions.
