Applications and general characteristics

• It controls and maintains a preset upstream pressure regardless of variations in flow rate.
• Equipped with non return valves, it closes automatically in case of backflow. (CL401C).
• Always mounted in line, it prevents the pump from reducing its suction pressure below the security point. It prevents also from exceeding the pumping capacity when the demand is higher.
