The A4A inlet family of regulators are compact, heavy duty, pilot operated, and have remarkable functionality. They sue upstream pressure for the opening force and require a minimum 0.14bar (2psig) pressure drop to open. These valves are normally ordered with close coupled upstream strainers to prevent the entrance of foreign materials into the valve and rest of system. The valve's purpose is to modulate flow of refrigerant gas or liquid to maintain constant upstream pressure as set-for, despite load fluctuations.
