Press Release Summary:

Designed with all ports on bottom, manifold mount RVA Series has 16 x 27 mm footprint and includes 2-way NC, 2-way NO, and 3-way versions supplied with PEEK valve bodies and perfluoroelastomer diaphragms and seals as standard. PPS valve bodies and FPM or EPDM diaphragm and seals are available. Intended for fluid control in automated clinical, analytical, and biotech chemistry applications, rocker type inert isolation valves can be supplied with built-in voltage dropping circuit.

Original Press Release:

New 2-Way & 3-Way Inert Isolation Valve Ideal for Automated Chemistry Applications

RVA Series Manifold Mount Valves feature small footprint, reduced energy consumption, and low heat generation. Can be used in continuous duty applications.

Hudson, MA – Clark Solutions introduces the RVA Series Rocker Type Inert Isolation Valve Series. The valves manifold mount and have very low internal volume and zero dead volume. Pumped volume is quite small as there is no volumetric change in the valve chamber with actuation of the rocker. They are ideal for fluid control in automated clinical, analytical and biotech chemistry applications.

Designed with all ports on the bottom and a very small, 16mm x 27mm footprints, RVA Series Valves make it possible to minimize the overall manifold size.

Offered in three versions: 2-way N.C., 2-way N.O., and 3-way, RVA Series Inert Isolation Valves are supplied with PEEK valve bodies and feature perfluoroelastomer diaphragms and seals.  RVA Valve models are also available with PPS valve bodies and FPM or EPDM diaphragm and seals.

RVA Series Rocker Type Isolation Valves are designed for continuous duty. Optionally they can be supplied with a built-in voltage dropping circuit that drops the voltage to a holding voltage 100 ms after the valve is energized. This built-in voltage dropping circuit reduces heat generation and energy consumption.
