MOP valves protect the compressor by limiting the increase of suction pressure.
The MOP value should be chosen for the max. permissible suction pressure of the compressor or min. 5 K higher than the required evaporating temperature of the system.
For orders without any MOP indication a valve with MOP + 10 °C will be delivered.
With gas charged valves and MOP it is under all operating conditions necessary that the bulb is always colder than the capillary tube and the thermal head!
With the Honeywell TLK series the thermal head is heated advantageously by the liquid refrigerant. The warm thermal head is on the safe side at any time.
