Miniature valves

Valve with extremely low transmission gradient

The unique features of the Ultra Low Carryover Gradient Valve ensure high accuracy of gradient generation in quaternary HPLC designs.

This is achieved through a combination of fast response times and a patented low volume, high flow fluid design.

This miniaturized valve allows a reduction in the overall size of the instrument and reduces the dead volume of the system. The exceptionally long service life and resistance to crystallization ensure that the valve will last throughout the life of the instrument.

R9 Valve - 9 mm miniature isolation valve with diaphragm

The Parker R9 Miniature Diaphragm Compact Series consists of 2-way and 3-way, 9 mm inert rocker valves. They are designed to provide the same fluid flow as a traditional 16mm valve, but with significantly less space requirements. Despite its compact size, the R9 can handle pressures up to 100 psi (6.9 bar) and offers exceptional performance for its size. With a 44 % reduction in width compared to larger valves, the R9 delivers high flow, low transmission and strong resistance to particles and crystallization. This makes it exceptionally well suited for demanding fluid handling applications in both current and next generation laboratory and portable instruments.
