930 Outlet Manifold Filter
Assembly with Check Valve
OPERATION
The 930 Series Outlet Manifold Filter has a built in spring actuated
check valve. It uses a replaceable filter element with a stainless
steel check ball permanently trapped inside the element.
The ele-
ment is available in the following screen sizes:
PART NO. MESH TYPICAL APPLICATIONS
930-005 5 Heavy materials, high builds, block
filters, elastomerics, multicolors, etc.
930-006 50* Conventional architectural and
protective coatings
930-007 100 Lacquers, stains, fine finishes
The filter cap has a long stem which acts as a spring guide and
controls ball travel within the filter element. The filter body has a
replaceable tungsten carbide seat which is secured by a PTFE
O-Ring.
The incorporation of this spring loaded check valve into the filter
manifold greatly reduces hydraulic shock at stroke changeover and
reduces opportunity for hydraulic stalls. Always use the 930 Series
Filter Element / Check Ball in the PowrTwin 5500™ System. Do not
use 920 Series filter elements. Do not run the PowrTwin 5500™
system without a 930 Series filter element/check ball. When using
heavy high viscosity materials, use the 5-mesh filter element/check
ball.
CLEANING
Clean filter regularly. Dirty or clogged filters can greatly reduce fil-
tering ability and cause a number of system problems including
poor spray patterns, clogged spray tips, etc.
To clean the filter, shutoff system and relieve all system pressure.
See the Pressure Relief Procedure on Page 12.
Remove filter cap with spring guide (1) and spring (2). Pull filter
element with check ball (3) straight out of filter body (10).
Thoroughly clean inside filter body (10) filter element with check
ball (3) and filter cap with spring guide (1) with appropriate solvent.
Use care in handling parts as dirt, debris, scratches or nicks may
prevent O-Rings or gaskets from sealing.
The 930 Series Filter Elements filter from the inside
out. Be certain to clean the screen element thoroughly
on the inside. Soak in solvent to loosen hardened
paint. etc. or replace.
SERVICE
NOTE: Inspect all parts thoroughly
.
1. Inspect ball trapped inside filter element (3). If ball has pressure
cuts or scratches, replace filter element.
2. If ball is cut, remove PTFE
O-Ring (6) with an O-Ring pick and
remove Tungsten Carbide Seat (7). Check carbide seat for nicks or
grooves. If seat is nicked or grooved replace.
3. Removal of the PTFE O-Ring (6) for Seat (7) inspection will
damage the O-Ring and require replacement.
4. Remove the Spring (2) from the Filter Cap (1). Measure the
length of the spring, uncompressed. If it measures less than 3/4"
from end to end, replace. Push spring back onto spring guide until
it "snaps" in place.
5. Inspect the PTFE Gaskets (4, 5) and O-Ring for deformity, nicks,
cuts, etc. Replace as required.
REASSEMBLY
NOTE: The PTFE
O-Ring (6) and
PTFE Gaskets (4, 5)l are
conveniently packaged in Service Kit, Part No. 930-050.
After inspecting and cleaning all parts,
reassemble.
1. Place Tungsten Carbide Seat (7) in filter body, using care to
place "beveled side" up.
2. Place PTFE
O-Ring (6) in groove on the O.D. of the Tungsten
Carbide Seat (7).
3. Place Filter element/check Ball (3) back in Filter Body (10).
Note: Top and bottom are identical.
4. Place Spring (2) back onto spring guide in Filter Cap (1). Push
spring onto guide rod until it "snaps" in place.
5. Place thin PTFE Gasket (5) onto step at top of the Filter Body
(10).
6. Place thick PTFE Gasket (4) onto top of the Gasket (15).
7. Tighten Filter Cap (1) onto Filter Body (10).
This will engage O-
Ring (6) against Tungsten Carbide Seat (7).
