This standard specifies the mounting surface dimensions of pressure control valves (excluding relief valves), sequence valves, unload valves, tie valves, and check valves to ensure compatibility. This standard mainly applies to the mounting surfaces of pressure control valves, sequence valves, unload valves, throttle valves, and check valves used in industrial machinery.
