The Phasecut Valve Controller is primarily designed to control Staefa valves. It modulates a valve using a 0 to 20V phase chopped output signal referenced to a 4~20mA Input control signal. A 4mA input signal represents a 0V of phase chopping and a 20mA control signal 20V of phase chopping.
Zero and Span adjustments are provided for fine tuning of the Phasecut to individual valves if required.
A dither adjustment is provided to prevent sticking of valves. For all adjustments turn anticlockwise to decrease and clockwise to increase that function.
