Product Description
- The SMC AKH check valve is used to prevent backflow in compressed air systems, particularly in applications involving tanks or storage modules.
- It is suitable for maintaining a vacuum for short periods and for protection against sudden pressure drops.
- Thanks to its compact design, it is ideal for installation in confined spaces or mobile systems.
- The non-return valve can be used with nylon, soft nylon or polyurethane hoses.
- The SMC AKH check valve consists of a nickel-plated brass body with an integrated valve made of NBR and aluminium alloy.
- A stainless steel spring ensures precise check valve function at a very low response pressure of 0.005 MPa.
- The valve body has a compact design and, thanks to large equivalent cross-sections ranging from 2.8 to 34 mm², allows for a high flow rate.
- The NBR O-ring ensures a reliable seal in a wide range of applications.
- The AKH non-return valve is fitted with push-fit connectors on both ends.
