RVA / RVB Series - Rocker valve with diaphragm isolation - 16mm grid width

Orifice diameter 0.8 und 1.6mm

RVA valve series
RVA 3-way valve


2/2-way and 3/2-way rocker type diaphragm isolation solenoid valves with fluid separation.

With 1.6 mm orifice diameter as standard, pressures of up to 2 bar and vacuum of up to -950 mbar are possible at all connections. At 0.8 mm orifice diameter up to 6 bar can be achieved, which makes its use in bidirectional fluidic systems at high pressure or vacuum.

Special designs with optimised pumping volume enable use in demanding analysis applications.

As an option, electronics can be integrated in the valve housing to reduce the holding voltage.

The flange connections of this valve series are available in different dimensions. Contact us for more information.
