Positive Control Regulators are used to modulate the Intake Valve and other system valves to control compressor output. Installed to sense compressor output pressure, this regulator stays closed up to a preset pressure and then modulates open to provide a positive control signal as compressor pressure increases. Within the spectrum of Positive Control Regulators there are two types with distinct differences; one utilizes a proportional response with downstream bleed to set gain and the operates off a differential response with factory set gain and adjustable set point.

Negative Control Regulators are used to modulate a normally closed intake valve and other system valves to control compressor output. Installed to sense compressor output pressure, this regulator stays open to a preset pressure and then modulates closed to provide a negative control signal as compressor pressure increases. The Negative Control Regulators come with a factory set gain and an adjustable set point.
