4-Wire Normally Closed Electric Zone Valve Actuator with 3' 3" Cable (24V)

Macon Model ZMC- ES 24V End switch is a thermoelectric valve drive for opening and closing valves and small valves used in the scope of HVAC technology. The integrated micro switch with floating contact allows direct operation of a pump or fan control unit. The Macon ZMC - ES 24V End switch is controlled by a 24 V room thermostat with two-point output or pulse-width modulation. Features: 360º installation position Integrated switch with floating contact Patented 100% protection against leaky valves Power consumption 1 watt Simple snap-on installation High functional safety and long expected service life First-Open function Adaptation check on valve Alignment aid on the valve Compact size, small dimensions All round function display Noiseless and maintenance-free The actuator mechanism of the Macon ZMC-ES with end switch uses a PTC resistor heated wax element and a compression spring. The wax element is heated by applying the operating voltage and moves the integrated ram. The force generated by this movement is transferred on the valve lifter and opens and closes the valve. The integrated micro switch allows the use of its switching signal depending on the opening of the valve.
