Radial-Diaphragm Valves

ASEPCO Weirless Radial-Diaphragm™ Valves

A multi-year winner of the Pharmaceutical Processing Innovations Award, ASEPCO Valves are specifically designed for applications where leakage, “dead legs,” or cross-contamination are unacceptable. All of our valves utilize radial-diaphragm technology which provides added security in all high-purity processes.We machine each valve from bar stock, so we have the flexibility to customize our valves to customer specifications. Our valves are machined in the U.S. from 316L SS bar stock (unless other material is requested). They assemble with a mere sanitary clamp, forming a seal that is the envy of weir-style valves, for it requires no tools, never leaks, and reduces maintenance costs by 80%.We have shipped more than 2,000 different valves. To help you find the valve you need, we organize our valves in these types and families. But don’t let these categories stop you! Call us if you don’t find what you need. We also build custom valve assemblies to match specific application requirements.
