AKH and AKB stainless steel check valves are used to control the direction of airflow in pneumatic piping. Their compact inline bodies make them suitable for equipment where installation space is limited and reverse flow needs to be prevented.
Air moving in the wrong direction can affect pressure stability and interfere with the normal operation of pneumatic equipment. AKH and AKB check valves provide a simple way to maintain one-way flow within the pipeline. Air passes through the valve in the permitted direction, while the internal mechanism helps stop it from returning when the pressure changes.
The compact stainless steel body is well suited to installations where a conventional check valve would take up too much room. These valves can be installed close to cylinders, manifolds, control valves or other pneumatic components. Their inline construction also helps keep the piping arrangement tidy.
AKH models combine a check valve with a compact connection body. Two configurations are available to suit different connection requirements. The direction symbol marked on the body gives the installer a quick reference when arranging the air line.
The push-in connection allows pneumatic tubing to be inserted without complicated assembly. This makes the AKH series convenient for machine building, maintenance work and piping layouts where components may need to be replaced or repositioned.
AKB is a threaded inline check valve with a hexagonal body. It can be installed between threaded pneumatic components or used where a direct threaded connection is preferred. The hexagonal section provides a practical gripping surface during installation.
Its straight body takes up little space and can be fitted directly into a compact air circuit. Different connection combinations are available, allowing the model to be selected according to the adjoining port sizes.
These check valves can be used in pneumatic control lines, automated assembly equipment, test fixtures, packaging machinery and general industrial air systems. They are useful for reducing reverse flow, isolating part of a circuit and helping retain pressure on one side of a pneumatic line.
Before ordering, check the required model, connection size and permitted airflow direction. The arrow or direction mark on the valve body should match the intended movement of air through the system. Tubing and threaded ports should also be checked carefully so that the selected code matches the actual piping arrangement.
