PROPORTIONAL CONTROL VALVES<br />
PV1 PROPORTIONAL VALVE<br />
Designed for industrial applications, the PV 1 delivers<br />
precise proportional control of pneumatic output by<br />
reading analog or digital input command signals<br />
generated by a programable controller or other remote<br />
power device. Response is instantaneous, precise and<br />
repeatable, relative to input command voltage.<br />
PV1 is activated by connection to a 15-24 VDC power<br />
supply. You can the use either analog or digital input<br />
signals to direct the PV1 to produce a proportional<br />
pneumatic output. This versatility in the module allows<br />
the use of a variety of controllers and other power<br />
devices for input signals.<br />
PV1 contains two external feedback features. The first<br />
is a 0-10 VDC linear output from a self-contained<br />
pressure sensor that monitors pressure at the output<br />
port. The second, a TTL (transistor-to-transistor logic)<br />
output, informs you that the PV1 has achieved the<br />
desired command pressure. Also provided is an<br />
indicator light on the unit visually signaling that<br />
command pressure has been achieved.<br />
