MIDI AIR FILTER PRESSURE REGULATORS (Aluminium)

MIDI AIR FILTER PRESSURE REGULATORS

Your air actuated instruments and equipments work at their best for a long period when you feed with clean dry air at a constant prescribed pressure. PLACKA MRP Series Air Filter-cum-Pressure Regulator remove completely the moisture and dust particles, and provides the exact pressure constantly at varying air demands. This economically priced unit is extensively used for process control instruments, Air actuated control valves, cylinders and other equipment , not requiring large bowl capacity. 

OPERATION

The primary air through the inlet port passes through the filter element, leaving down the contaminants in the blow. When the knob is adjusted suitably, the springs act on the diaphragm which in turn actuates the main valve to allow the pure secondary air at a particular pressure to the outlet. The main valve is supported between the relief valve and the main valve spring, eliminating the need for stem guiding. Toggle action between main valve and relief valve completely alignment problems and thus erratic output pressure variation.

REGULATION CHARACTERISTICS

The secondary pressure at the bottom of the diaphragm balances against the set position of the main spring to keep the main valve at the adjusted position. When the secondary pressure rises above the set point, it pushes the diaphragm away from the relief valve and the excess air finds its way to atmosphere through the bleed hole.

Flow Characteristics

When air flow the regulator is increased the secondary pressure falls below the set point. This ‘pressure drop’ in supply will force your equipment to function erratically. But PLACKA Air Set reduces the pressure drop successfully by an aspirator. The aspirator connects the outlet port and the chamber under the diaphragm. When flow increases the aspirator creates a lower pressure below the diaphragm, which in turn force the main valve to open further and thus more air flows in to compensate for the pressure drop
