Universal Uniblast F119-013 Female Low-Pressure Pop-Up Valve – Pressure Blast Vessel

Maintain proper sealing and pressurization of your Universal / Uniblast pressure blasting equipment with the Universal Equipment Manufacturing / Uniblast Technologies F119-013 Female Pop-Up Valve.

This female-style, low-pressure pop-up valve is used in Universal / Uniblast pressure vessel systems as part of the vessel filling and sealing assembly. When the system is pressurized, the pop-up closes the vessel opening so operating pressure can build inside the abrasive vessel.

What the Pop-Up Valve Does

The F119-013 pop-up valve is part of the pressure vessel's pressurization and sealing system.

When compressed air enters the system, the pop-up moves upward into its sealing position, closing the vessel's filling opening. Once properly seated, the vessel can build pressure for pressure-blast operation.

When the vessel is completely depressurized, the pop-up drops away from the opening so abrasive media can be loaded into the vessel.

Female / Low-Pressure Configuration

The exact configuration is particularly important with these Universal / Uniblast pop-up components:

Customers should verify the original part number and vessel configuration rather than ordering based solely on appearance.

Similar Universal / Uniblast Pop-Up Valves

• F119-012 / C639 – Male Pop-Up Valve – Item #7
• F119-013 – Female Low-Pressure Pop-Up Valve – Item #8
• F119-028 – Female Urethane Low-Pressure Pop-Up Valve – Item #10

Although these components perform similar functions, they should not be assumed to be interchangeable. Verify the original part number and pressure-vessel configuration before ordering.

Common Reasons for Replacement:

• Pop-up is worn or damaged
• Sealing surface is nicked, gouged, or deteriorated
• Pop-up does not move freely
• Vessel leaks around the filling opening
• Vessel is slow to build pressure
• Vessel will not maintain pressure properly
• Pop-up does not seat consistently
• Existing component was damaged during service
• Rebuilding an older Universal / Uniblast pressure vessel

If the Vessel Won't Seal

A leaking vessel opening doesn't necessarily mean the pop-up itself is the only problem.

When servicing the F119-013, inspect the complete sealing area, including:

• Pop-up valve
• Mating seat
• O-ring or seal
• Sealing surfaces
• Pop-up operating components
• Abrasive or debris around the sealing area

Even a good pop-up may not seal correctly if abrasive media is trapped between the mating surfaces or if the corresponding seal or seat is damaged.

Inspect During Routine Vessel Maintenance

Pressure-vessel pop-up components operate every time the machine is pressurized and depressurized. Regular inspection can help identify wear before it causes unreliable operation.

Look for damage, excessive wear, distortion, corrosion, abrasive buildup, and anything that could prevent the pop-up from moving freely or seating correctly.

Finding Parts for Older Universal / Uniblast Equipment

Universal Equipment Manufacturing and Uniblast Technologies pressure blasting systems can remain in industrial service for many years, but individual vessel components can be difficult to identify from older manuals and exploded diagrams.

That's why we include the original manufacturer part number, pop-up configuration, pressure designation, and exploded diagram item number whenever possible.

For this component, the key identification information is:

Universal / Uniblast F119-013 – Female Low-Pressure Pop-Up Valve – Diagram Item #8

Important:

This listing is for one Universal Equipment Manufacturing / Uniblast Technologies F119-013 Female Low-Pressure Pop-Up Valve, identified as Item #8 in the exploded parts diagram.

This is the FEMALE / LOW-PRESSURE configuration.

O-rings, seats, pressure vessels, handway components, valves, piping, and other parts shown in the exploded diagram are sold separately unless specifically stated otherwise.

Always verify the F119-013 part number, female configuration, and low-pressure application before ordering.

Pressure Vessel Safety

Completely depressurize and isolate the blasting system before servicing the pop-up valve or any pressure-vessel component. Never loosen, remove, adjust, or service the pop-up assembly while the vessel is pressurized.

After installation, inspect the complete sealing system and verify that the pop-up operates and seals correctly before returning the equipment to service.
