Williams 112803 WM400A 1/2" Pressure Regulator

Capable of high volume air flow, the WM400 series regulators are used in industrial applications to limit the output to a pre-adjusted maximum. Each regulator consists of a three-way, self-relieving WM352A pressure modulator and an actuating assembly that includes an adjustable screw. The regulator's output, which falls within a specific compensating range, corresponds to the position of this screw.
