Universal Uniblast F119-028 Female Urethane Low-Pressure Pop-Up Valve

Maintain proper sealing and pressurization of your Universal / Uniblast pressure blasting equipment with the Universal Equipment Manufacturing / Uniblast Technologies F119-028 Female Urethane Pop-Up Valve.

This female-style urethane pop-up valve is specifically identified as a low-pressure pop-up for Universal / Uniblast pressure vessel systems. The urethane construction provides a resilient sealing surface for repeated pressurization and depressurization cycles.

What the Pop-Up Valve Does

The F119-028 pop-up valve is part of the pressure vessel's sealing and pressurization system.

When the blast system is activated and the vessel begins to pressurize, the pop-up moves into position against its mating seal or seat. This closes the vessel opening so pressure can build inside the abrasive vessel.

When the vessel is depressurized, the pop-up drops away from the sealing position, allowing access to the vessel opening for filling with abrasive media.

Female Urethane / Low-Pressure Configuration

The configuration is particularly important when ordering this component:

F119-028 = Female Urethane Pop-Up Valve – Low Pressure

Universal / Uniblast pressure vessel systems may use different pop-up configurations, so customers should not select a pop-up based on appearance alone.

Verify the:

• F119-028 part number
• Female configuration
• Urethane construction
• Low-pressure application

before ordering.

Why Urethane Is Used

The urethane pop-up provides a resilient surface that can repeatedly contact the mating sealing area as the vessel is pressurized and depressurized.

Over time, repeated cycling, abrasive contamination, and normal wear can damage or deform the sealing surface. Once the pop-up can no longer seat properly, the vessel may leak air around the filling opening or have difficulty building pressure.

Common Reasons for Replacement:

• Urethane is worn or deteriorated
• Sealing surface is cut, gouged, or damaged
• Pop-up has become distorted
• Air leaks around the vessel opening during pressurization
• Vessel is slow or unable to build pressure
• Pop-up does not seat consistently
• Existing pop-up is damaged during vessel service
• Rebuilding an older Universal / Uniblast pressure vessel

If the Vessel Won't Seal

A worn pop-up isn't the only possible cause of a leak at the vessel opening.

When servicing the F119-028, also inspect the mating O-ring/seat, sealing surfaces, pop-up mechanism, and surrounding components for wear, contamination, or damage.

A new pop-up cannot seal correctly against a damaged or contaminated mating surface.

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 pressure-vessel components can become difficult to identify from older parts diagrams.

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

For this component, the key identification information is:

Universal / Uniblast F119-028 – Female Urethane Low-Pressure Pop-Up Valve – Diagram Item #10

Important:

This listing is for one Universal Equipment Manufacturing / Uniblast Technologies F119-028 Female Urethane Low-Pressure Pop-Up Valve, identified as Item #10 in the exploded parts diagram.

The pop-up seat, O-ring, pressure vessel, handway assembly, valves, piping, and other components are sold separately unless specifically stated otherwise.

Always verify the F119-028 part number, female configuration, urethane construction, 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 proper vessel operation before returning the equipment to service.
