Titan 700-258 Paint Sprayer Prime/Spray By-Pass Valve Assembly

The Titan 700-258 Paint Sprayer Prime/Spray By-Pass Valve Assembly manages material routing between spraying and bypass flow, supporting controlled paint movement through the sprayer during operation.

This part corrects the following symptoms:

• Sprayer remains in bypass instead of through the spray path.

• Paint flow becomes weak during spraying.

• Prime operation does not draw coating properly.

• Pressure changes occur switching between prime & spray modes.

• Material continues circulating when spray delivery is selected.

By-Pass Flow Stays Active

Quick Check: Observe whether paint continues returning through the bypass path during spraying.

Fix Suggestion: Clear residue around the valve passage and verify movement of internal components.

Prevention Tip: Flush remaining coating from the valve area after extended spraying sessions.

Weak Paint Delivery

Quick Check: Monitor coating output while moving the valve from prime toward spray.

Fix Suggestion: Remove accumulated material deposits that may restrict the valve opening.

Prevention Tip: Keep paint properly filtered before it enters the sprayer system.

Poor Priming Response

Quick Check: Watch whether coating begins moving through the prime path promptly.

Fix Suggestion: Clean the valve passage and confirm unrestricted material movement through the assembly.

Prevention Tip: Avoid leaving unused coating inside the sprayer between applications.

Pressure Changes During Mode Selection

Quick Check: Observe pressure behavior while switching between prime and spray positions.

Fix Suggestion: Examine the valve seating area for residue or unusual wear patterns.

Prevention Tip: Operate the selector gradually without forcing the valve through its positions.

Customer Experience: A customer found that the Titan 700-258 valve assembly provided smoother material routing after the valve area was cleaned.
