Where low actuation forces and high-flow rates are required - employ lever-actuated Series 3 sensor valves.
The mechanically-operated designs also known as "whisker valves" are designed to be used as limit switches in control applications.
Actuation force of Series 3's mechanical lever is less than 0.5 lb (2N) at 90 psi. Actuation sensitivity may be increased by adding a 3-mm-diameter "whisker rod" to the predrilled hole at the end of the lever. When the mechanical lever is actuated, it releases an internal pilot signal to atmosphere. Depressurization of the spool plunger allows the internal mechanical spring to shift the valve spool.
