Extended Life Schedule 80 Heavy-Duty Nipples

• Designed to resist abrasive wear for extended service life

Bolt Clamps on Pusher Line

• Enable quick field repairs

Combination Valve / APVII Valve

• Two-in-one valve design cycles the top chamber automatically

• Quadruple-seal APVII metering valve prevents air & abrasive carryover

• Solid tungsten carbide plunger and sleeve for extreme wear resistance

• 1" NPT clean-out port for easy maintenance and draining

• Relieving control handle reduces air consumption and stopping times

15' Blowdown Hose Assembly for Remote Mounting

9" Adjustable Spider

• Adjusts for different media sizes and types

• Keeps abrasive weight off pop-up seal for proper closure

Skirted Pop-Up Gasket

• Cuts through abrasive for tight sealing

• Prevents burping issues common in hopper-feed systems

• Ideal for large-grit abrasives

Union End Ball Valves

• Allow bottom shut-off for maintenance without dumping media

Full Load Lifting Eyes

• Enable safe lifting and placement for service or transport
