Our Weirless Radial-Diaphragm™ Sterile Access Valve combines a valve and a tee, giving you two flowpaths in one compact device. This design eliminates extra connection fittings, saving you space and money. When your process fluid is valuable, the increased hold up volume costs you serious money. Using our Sterile Access Valve, you’ll minimize the hold-up volume in your system. You’ll have more product make it to market. Also, with fewer fittings, clamps, and gaskets to clean, your cleaning time and effort is optimized.

This valve uses our contamination-free, radial-diaphragm technology and easy-to-use clamp assembly, making it a reliable valve that is easy to assemble and inspect. It never needs adjusting or re-tightening.

We’ve designed hundreds of special valves by customer request. Call us to talk about your special needs.

Valve sizes: 0.5″ compact, 0.75″, 1.0″, and 1.5″
