Pressure & Temperature Regulating Valve

Product Description

 Pilot Operated Main Valves for

Regulating Pressure and Temperature

PME valves are pilot operated main valves for regulating pressure and temperature in refrigeration systems.

PME main valves can be used on the high and low-pressure sides, in wet and dry suction lines, and in liquid lines without phase change (i.e. where no expansion takes place in the valve).

The function of a PME valve depends solely on the pilot pressure applied to the valve, either from pilot valves or in the form of external pilot pressure.

PME 1 has one connection for pilot pressure/pilot valve, while PME 3 has three pilot pressure/pilot valve connections.

The associated Danfoss pilot valves can either be screwed direct into the main valve or be connected via an external pilot line. Several pilot valves can be used on one main valve to give a large number of different functions.

The PME valve top cover has a pressure gauge connection so that the inlet pressure can be measured when, for example, main valve function must be set or adjusted in relation to the system regulation performed by the pilot valves.

The spindle in the top cover of the main PME valve can be used to manually open and close the valve (although PME 65 cannot be opened fully in this way).
