Lacquer Pressure Regulator PRM-2007, mechanical
1. Introduction ^^ to top
The APSON Lacquer Pressure Regulator PRM-2007 is a mechanically controllable pressure regulator for frequently changing aggressive use-media/working-materials. It holds the working material pressure at the
output constant and independent of pressure fluctuations of the working material supply system at the input of the controller, if the input pressure is greater than the preset output pressure. The controller is optimized for
good rinsing and low solvent consumption. It is particularly suitable for use in automatic systems for the processing of paints, solvents, alkalis, a.o.

2. Features ^^ to top
- Environmental carefully due to short rinsing times.
- Very good rinsing barness and small solvent consumption.
- Compact design, large throughput and small pressure losses.
- Fast exchange of a defective diaphragm (2 minutes).
- Simple handling at assembling, adjustment and maintenance.
- Rational maintenance and spareparts holding.
3. Structure and Function ^^ to top
The APSON Lacquer Pressure Regulator PRM-2007 consists mainly of a pressure chamber provided with a throttle. The chamber is separated by means of a solvent-resistant membrane / diaphragm from the main spring
chamber. This pressure regulator is a robust flow through controller. Regulator behaviour under normal operating conditions: (a) it regulates if through the regulator flows medium, (b) it closes if the output is closed, and
(c) it regulates again once the output is opened.

Legend:
1=input, 2=input port, 3=lower casing part, 4=closing spring, 5=sealing ball, 6=sealing ring, 7=thrust piece, 8=diaphragm, 9=vent hole (for this regulator type it has no function), 10=diaphragm fastening nut, 11=locking nut, 12=overthrow/union nut, 13=upper housing part, 14=main spring, 15=threaded hole (for grub screw to lock the adjustment nut), 16=adjustment nut, 17=spring holder, 18=ball, 19=press bushing, 20=pressure pin,
21=vertical pressure gauge (radial connector), 22=pressure gauge seal, 23=riser-pipe, 24=centering pin, 25=riser-pipe mounting nut, 26=sealing ring, 27=sealing ring, 28=output port resp. output.
An axial removal/approach of the sealing ball from/to seal effects between them a different wide opening, called throttle. The thrust piece connected to the diaphragm controls thus by the sealing ball, the working material amount per time unit, flowing
through the pressure regulator and keeps the output pressure constant. The regulation process is achieved by the balance of forces on the diaphragm. On the diaphragm acts on one side the main spring and on the other side, the
closing spring as well as the resultant force due to the pressure of the working material/medium at the output of the regulator.
The desired working material pressure at the outlet of the regulator is adjusted by manually rotating the adjustment nut of the regulator. For rinsing of the pressure regulator the adjustment nut must be set to a predetermined value, so that the throttle
is fully opened.
Important: Due to the gas column in the rising pipe of the pressure gauge, the pressure regulator is to be operated in vertical position. When exchanging the diaphragm it is to be made certain that the Teflon™-coated
surface of the diaphragm points into the direction of the working material. For storage of the controller, the diaphragm should be relieved.
