After the pump, coating passes a high-pressure outlet filter, and the bleed valve is how you relieve pressure. On the 730 to 975 the filter element is the 920-004 (listed as 50 mesh) and the bleed valve wear parts are the 944-904 tungsten seat and 761-715 ball. The 630 and the 1045 to 1072 use the 0533514 element and the 0533517 bleed valve assembly.
What the outlet filter and bleed valve do
Every PowrCoat has a high-capacity filter on the fluid outlet, with 3/8 in. and 1/4 in. outlets, according to Titan. It sits between the pump and the hose so that lumps and debris stop there instead of reaching the gun and tip. Like any filter on an airless system, a partly blocked one cuts pressure and causes pulsing and spitting, so it is the first thing to clean when a good tip starts to misbehave.
The bleed valve is the other half of this section. In Titan's 1045 manual, opening the bleed valve is part of the pressure relief procedure, so it gets used at the end of every job. That makes its seat and ball the small parts that do the most work for their size. Read your own model's manual for the procedure: the steps are written for your machine, so do not work from this page.
Filter parts on the 730 to 975
The 730, 745, 940, 960 and 975 share one design of filter, and the pages are near-identical: see the 940 page or the 975 page. Titan's manual data for the 940, 960 and 975 gives a standard 50 mesh insert with 18 square inches of filter area. The parts as the diagrams list them:
Outlet filter parts, 730 to 975
The same pages list a stainless ball, 920-103, plus fittings and pipe plugs. Note that the 730 and 745 pages do not list the 920-005 manifold filter or the 920-007 long screen, while the 940, 960 and 975 pages do. That is a good example of why you should open the page for your own model.
Filter parts on the 630 and 1045 to 1072
The 630 and the three biggest models use a different filter design, and the bleed valve is listed on the same page instead of a page of its own. See the 630 page and the 1045 page; the 1064 and 1072 pages carry the same list as the 1045.
- 0533514 filter element, with 0533515 filter support and 0533513 spring.
- 0533517 bleed valve assembly, listed on the filter page as a complete unit.
- On the 1045, 1064 and 1072: 0533858 filter body, 0533854 filter cap, and gaskets 0533855 and 0533856.
- On the 630: 0533523 PTFE gasket, 0533533 O-ring, and the 0533127 return tube assembly.
We do not give a mesh for the 0533514 element, because the sources disagree on it for the 630. If the mesh matters for your coating, confirm it with our parts team on (713) 931-0006 before you order.
Bleed valve parts on the 730 to 975
On these models the bleed valve has its own page, for example the 960 bleed valve page or the 940 bleed valve page. It lists seven parts, and the numbers are identical across the 730, 745, 940, 960 and 975.
Bleed valve parts, PowrCoat 730 to 975
| Part | Name on the diagram | What it is for |
|---|---|---|
| 944-904 | Tungsten valve seat | The seat the ball closes against; one of the two sealing parts |
| 761-715 | 1/4 tungsten ball | The other sealing part, with the seat |
| 944-004 | O-ring, PTFE | A seal in the valve |
| 945-003 | Copper gasket | A seal in the valve |
| 944-020 | Valve housing | The body of the valve |
| 944-026 | Valve stem stop | The stop for the valve stem |
| 944-024 | Knob | The handle you turn |
The 730, 745, 940, 960 and 975 wall mount pages also list a complete bleed valve assembly, 944-028A, for when the whole valve is the problem.
When to look at them
Symptoms at the outlet and what to check
| What you see | Check first | Then consider |
|---|---|---|
| Pressure drops, pulsing or spitting with a tip that looks fine | Clean the outlet filter element | Replace the element or its gaskets if cleaning does not help |
| The pattern is coarse or streaky | The tip, which wears wider | Filter, then the fluid section |
| Coating keeps escaping from the bleed hose with the valve closed | Valve seat and ball | The O-ring and copper gasket, then the housing |
Start with the quick checks, and relieve pressure before every one.
The first row is the one that matters most, because it is the commonest and the quickest. Most blocked outlet filters turn out to be dirty, not worn out. A worn element looks damaged when you take it out: replace it then, rather than on a timetable. Titan does not publish a service life for the element, the seat or the ball.
Clean after every job
Flush the sprayer after every use and clean the filters at the same time. Never leave latex or another coating to dry in the pump, hose, filter or gun. Use the filter mesh your coating needs: a finer mesh for fine finishes catches more but blocks sooner, so match it to the material instead of fitting the finest one you can find.
Outlet filter and bleed valve parts from the lists above:
The Short Version
The outlet filter and bleed valve are small, and they decide whether a PowrCoat sprays cleanly and shuts down safely. Clean the element after each job, keep a 944-904 seat and 761-715 ball on the shelf if you have a 730 to 975, and always order from the page for your model.
