Long-lasting, quick-change diaphragms

The valve diaphragm can be changed in seconds, without special training or tools. Customers tell us this reduces maintenance time by as much as 80% compared to other valve technologies. Our patented, radial shoulder seal design gives consistent, leak-free, uniform sealing.
