Humphrey Products introduces new proportional valve driver

Humphrey Products has introduced thehumphrey latest product within the company’s ProControl family, the PCD proportional valve driver. The PCD produces the appropriate current control, either constant current or PWM, to effectively drive any ProControl proportional valve upon receiving signal from a variety of data acquisition sources (ie PLCs, IoT, closed loop sensors, etc).

Suitable for product development, laboratories and production environments, the PCD is flexible and user friendly. The PCD features an LCD screen, scroll wheel and pushbutton parameter setting, and tool-less connectivity making set-up fast and easy. Pre-programming includes default settings for all Humphrey ProControl valves and a custom setting for unique application settings.

Each PCD is shipped with installation instructions. Unlike competitive proportional valve drivers, the PCD is 100% programmable with fine setting control, no pots or switches to set, and capable of use with any proportional valve specified 1 amp or less with the “custom” setting. It accepts a variety of control signals, namely 0-5v, 0-10v or 4-20mA. Included is short circuit and reverse polarity protection.
