CLEANING / REPLACEMENT OF THE SUCTION AND DELIVERY BALL VALVES

a) Remove the suction and delivery manifold.
b) Remove the seals, seats and balls from the diaphragm covers and the manifolds' h ousings.
c) Check the condition of wear of the ball guide/stops inside the diaphragm covers and
manifolds. Replace if worn.
d) Remove all dirt particles as well as hardened material residues. Check the ball and
seats for excessive wear. Clean or replace the components.
e) Clean the contact surfaces of the manifolds and the diaphragm covers and assemble
the components.
To the directions in Chapter 11 apply the right torque.
It is recommended that the static seals be replaced when reassembling.

REPLACEMENT OF THE REVERSING VALVE

a) Disassemble the pressure side cover and remove the reversing valve.
b) To clean it, blow the housing cavity of the reversing valve out with a jet of compressed
air (wear safety goggles).
c) Put the new reversing valve in its housing. There apply the right torque (see picture
in Chapter 9.4). Mount the valve slider (6) on one of the stroke stop positions. There
are four possible positions, each of them is suitable. Attach the pressure side cover.
During the performance of the operations described above, check the positioning of the
valve's seals and cover including the seal. To the directions in Chapter 11 apply the right
torque.

MATERIAL HOSES

The lifetime of the fl uid hoses is, even with appropriate handling, reduced due to
environmental infl uences.
Check pipes, tubes, and couplings every day and replace if necessary.
As a precaution fl uid hoses should be replaced after a period specifi ed by the plant
operator.
Bursting hose, bursting threaded joints!
Danger to life from injection of material.
ORDER NUMBER DOC 2332848
WARNING
Ensure that the hose material is chemically resistant to the
sprayed materials.
Ensure that the spray gun, threaded joints and material hose
between the unit and the spray gun are suitable for the pressure
generated in the unit.
