Camozzi’s Series 3 lever-actuated sensor valves function as limit switches in control applications.0
Camozzi Pneumatics released its Series 3 mechanically-operated sensor valve (i.e. whisker valve), which can function as a limit switch in applications where very low actuation forces and high-flow rates are required. The actuation force of the valve’s mechanical lever is less than 0.5 lb (2N) at 90 psi operating pressure. The actuation sensitivity may be increased by adding a 3mm diameter “whisker rod” to the pre-drilled hole at the end of the lever. When the mechanical lever is actuated, it releases an internal pilot signal to atmosphere. The depressurization of the spool plunger allows the internal mechanical spring to shift the valve spool. The valve Functions as either 3-way/2-position normally closed or normally open (spring return), and 5-way/2-position (spring return). It features 1/8-inch NPTF or BSPP ports and operates at 32°F – 175°F and pressures from 58 – 145 psi.
