Pressure Regulators- A4AD Adaptomode A463E400A7B4S50B34YXSN

The Type A4AD is a Dual Inlet Pressure Regulator capable of regulating at two different pressure set-points.

Parker’s A4AD pressure regulator features dual pressure regulating pilots in a single housing which allows users to control two different pressure set points without the need for additional piping, valves, or controls. The active pressure regulating pilot is selected using a standard pilot solenoid. This simple control gives users flexibility in their process but keeps implementation costs to a minimum. The A4AD is part of the popular A4A line and features common components and service parts.
