The R9 Miniature Diaphragm Compact family of 2 and 3-way 9 mm inert rocker isolation valves designed to offer the flow of larger 16mm valves in a much smaller space while also offering the advantage of pressures up to 100 psi (6.9 bar).

The R9 delivers the liquid flow capabilities of a 16mm valve with a 9mm envelope. A 44% reduction in width with unrivaled flows and pressures up to 100 psi (6.9 bar) in a smaller space. Designed to offer low carryover performance with particulate and crystallization resistant. This valve is ideally suited for today's demanding liquid handling applications. The R9 supports the performance requirements of current and future laboratory and portable instrumentation.
