A DIN 2401 Gate Valve is a gate valve marked and identified in compliance with the DIN 2401 standard, which is used for the marking and identification of valves, including gate valves, according to German standards. This ensures that gate valves are accurately labeled with essential information for proper installation and operation. These valves function as control valves, allowing fluid flow through unobstructed passages or stopping the flow as needed, with the advantage of inducing minimal pressure loss.
