1. Introduction to top
The APSON Backflow Controlvalve BCV-2002-M is a
mechanically adjustable overpressure valve for
large throughput. It is particularly suitable for aggressive media,
e.g. lacquers, solvents, caustic solutions, a.o.
The controlvalve releases the flow to the output, as long as the
medium pressure at the input exceeds a manually preset value. It is
specially optimized for good rinsing barness and is particularly
suitable for the application in painting plants, for lacquer
backflow-pressure adjustment or as dynamic bypass in automatic
systems.
2. Structure and Function to top
The APSON Backflow Controlvalve BCV-2002-M consists of a medium
pressure chamber, which is separate from the compression spring
chamber by means of a solvent-resistent diaphragm. The diaphragm is
subjected on the Teflon™-coated side by the medium under pressure
which has to be controlled and on the other side by the compression
spring.
A sealing stamp connected with the diaphragm opens, as long as
medium over-pressure at the input prevails. The desired medium
pressure at the output of the backflow controlvalve is adjusted
mechanically by means of the adjusting nut. For rinsing the backflow
controlvalve, the compression spring must be relieved. In order to
manage this, the adjusting nut is to be turned to the left (counter
clockwise direction).
Importantly: When exchanging
the diaphragm it is to be made certain that the Teflon™- coated
surface of the diaphragm points to the medium side. The backflow
controlvalve is to be installed preferably with the diaphragm in
horizontal plane.
-
Environmental carefully due to short rinsing times.
-
Good rinsing barness and small solvent consumption.
-
Small pressure losses.
-
Rational maintenance and holding of spareparts.
-
Very fast exchange of a defective diaphragm
(2 minutes).
-
Simplest handling at assembling, adjustment and
maintenance.
-
Small, very compact size.
