PV-500 Proportional Valve

Product Description

 

PV-500 is a multi-functional controller. The internal electronic control circuit provides

PWM, pressure regulation, and analogue signal (0-5Vdc / 0-10Vdc / 4-20 mA / PT100)

coming from different types of terminal sensor (temperature, pressure, flow rate…etc). The

controller simulates a unique PID circuit through the internal electronic control circuit to

allow modulation at the terminal.

PV-500 can be operated in 4 modes:

◆ Mode01-PWM

Users may select different analogue signal (including 0-5Vdc / 0-10 Vd/ 4-20 mA) as a

control signal. The modulation of device (coil, LED light..etc) can be achieved through the

internally built PWM functionality which modulates DC 24V.

◆ Mode02-PWM + Feedback

The controller receives the feedback analogue signal (incl. 0-5Vdc / 0-10Vdc/ 4-20

mA/ PT100) of terminal sensor (temperature, pressure, flow rate..etc) and thereby achieve

terminal modulation functionality through PWM and a unique PID circuit simulation.

◆ Mode03-I/P、E/P

A closed loop electronic pressure regulator consists of 2 solenoid valves, one internal

pressure transducer, and an electronic control circuit. Users may select different analogue

signals (incl. 0-5Vdc/ 0-10Vdc/ 4-20 mA) as control signal. The output pressure is

proportional to the input electrical signal (command signal). By adjusting the level of

activation on solenoid valves with PWM, inlet and exhaust can be controlled. This will

thereby achieve modulation function through the internal pressure transducer signal(=

command signal).

◆ Mode04-I/P、EP + Feedback

The controller receives the feedback analogue signal (incl. 0-5Vdc / 0-10Vdc/ 4-20

mA/ PT100) of terminal sensor (temperature, pressure, flow rate…etc). This thereby

achieves terminal modulation functionality through PWM (which adjusts the level of

activation on solenoid valves) and a unique PID circuit simulation to adjust the opening of

the pneumatic valve by varying inlet and exhaust.
