Series 18 - Miniature multi-channel inert PTFE distribution valve
Parker's 18 series of PTFE manifold isolation valves provide an inert liquid-touched surface for biocompatibility and aggressive fluids with fast multi-channel response times with precise fluid control.
Parker Series 18 is designed for compact installation in multi-liquid systems. Available with multiple inlets and one outlet (or vice versa), Series 18 has all fluid-affected parts in PTFE.
In the Series 18, piping and connections between separate valves have been eliminated and dead volume reduced. Repeatability and fast response time make the Series 18 ideal for accurately controlling small percentages of low flow fluids.

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. -
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 by a combination of fast response times and a patented low volume, high throughput fluid design. This miniaturized valve allows for 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 for the life of the instrument. -
Ultra low transmission valve
The Ultra Low Carryover Valve has both unprecedented low carryover and the ability to reduce fluid circuit complexity by replacing multiple valves with a single valve. The valve uses a patent-pending method to increase throughput and reduce fluid waste by reducing wash times. In addition, the Ultra Low Carryover Valve offers superior performance as a gradient proportioning valve for HPLC, HbA1c and other life science applications. -
X-Valve - Miniature pneumatic solenoid valve
