Superlok® Diaphragm Valves

Superlok Diaphragm Valves are sourced through Superlok® USA, which holds one of the most extensive inventories of diaphragm valves in the country. Built to meet the strict standards of semiconductor, pharmaceutical, and high-purity chemical systems, our diaphragm valves deliver precision, longevity, and ultra-clean reliability. Whether you’re outfitting a cleanroom, managing contamination risk, or streamlining isolation in a sampling line, Superlok valves consistently perform—without the markup.

Cleaner Design for Critical Environments:

Superlok’s sealed body construction prevents contamination at the source. Precision electropolishing, smooth internal finishes, and cleanroom assembly help ensure every valve meets the high-purity needs of controlled environments – without compromising performance or price.

Built to Go the Distance:

Superlok valves are designed for extended use cycles and reduced maintenance intervals. You get fewer changeouts, faster lead times, and tighter cost control—backed by consistent availability and competitive pricing.

Certified Cleanroom Assembly:

Every diaphragm valve is cleaned with deionized water, assembled in a cleanroom, and tested to strict quality standards. This eliminates surface contamination and keeps your processes clean from start to finish.

Same Function, More Flexibility:

Used in gas control, analyzer sampling, and ultra-pure isolation systems, our diaphragm valves cover the same applications as Swagelok®—with more material options and better lead times.

High Purity, Lower Cost:

You don’t have to trade quality for cost. Superlok diaphragm valves deliver purity, performance, and compatibility—all while keeping inventory in stock and budgets intact.
