What the Foot Pedal Valve Does

The F122-042 foot valve provides operator control of the blast cabinet's pneumatic blasting function.

Using a foot-operated control allows the operator to start and stop blasting without removing their hands from the cabinet gloves. This provides convenient control while positioning the workpiece and directing the blast gun.

When the pedal is released, the system should return to its non-blasting condition. Because of this control function, proper operation of the foot valve is important to both machine performance and operator safety.

Common Reasons for Replacement:

• Foot pedal no longer operates reliably
• Valve sticks or does not return properly
• Air leakage from the foot valve
• Intermittent blasting operation
• Internal valve wear
• Physical damage to the pedal or valve assembly
• Existing foot valve is missing
• Restoring an older Universal / Uniblast blast cabinet

Important – Post-December 1991 Application

The production date matters on this part:

Earlier equipment may use a different foot-control arrangement. Customers should verify the F122-042 part number and approximate equipment manufacture date before ordering.

Related F122-043 Base / Shroud

The F122-043 Foot Valve Base / Shroud is used with this F122-042 Foot Valve.

• F122-042: Complete Foot Pedal Valve
• F122-043: Foot Valve Base / Shroud

The base/shroud is a separate service component and is not included unless specifically stated otherwise.

Inspect the Foot Control System

When servicing the foot valve, inspect the surrounding pneumatic components for:

• Cracked, hardened, or damaged air tubing
• Loose fittings
• Air leaks
• Damaged pedal components
• Restricted or kinked tubing
• Contamination inside pneumatic lines
• Pedal binding or sticking
• Improper return when the pedal is released

After installation, cycle the foot valve several times and verify that the blasting system starts and stops correctly with pedal operation.

Finding Parts for Older Universal / Uniblast Equipment

Universal Equipment Manufacturing and Uniblast Technologies blast cabinets have been used in industrial applications for many years, and control components can vary according to the age and configuration of the machine.

That's why we include the original manufacturer part number, equipment date information, related component numbers, and exploded diagram item number whenever possible.

For this component, the key identification information is:

Universal / Uniblast F122-042 – Foot Pedal Valve – Post-December 1991 – Diagram Item #17

Important:

This listing is for one complete Universal Equipment Manufacturing / Uniblast Technologies F122-042 Foot Pedal Valve for post-December 1991 equipment, identified as Item #17 in the exploded parts diagram.

The F122-043 base/shroud and other components shown in the exploded diagram are sold separately unless specifically stated otherwise.

Always verify the F122-042 part number and post-December 1991 application before ordering.

Disconnect electrical power and completely shut off and relieve compressed-air pressure before servicing the foot valve or pneumatic control system. After installation, verify that the blasting function starts correctly when commanded and stops completely when the foot pedal is released before returning the cabinet to service.
