Pop-Up Valves: The Safest Option for Decades

Simple. Time Proven. Safe.

Pop-up valves have been used in smaller blast machines throughout the industry by all manufacturers for decades—because they are the safest option.

No Guessing

After a pot pressurizes, its pop-up valve seals. After it depressurizes, the valve drops. No guessing, and your crew can refill the pot right away.
