Product Description
- The AKH non-return valve is used to prevent backflow in compressed air systems, particularly in applications with tanks or storage modules.
- It is suitable for maintaining a vacuum for short periods and for protecting 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 AKH non-return valve consists of a nickel-plated brass housing with an integrated valve made of NBR and aluminium alloy.
- A stainless steel spring ensures precise non-return function at a very low response pressure of 0.005 MPa.
- The valve body has a compact design and enables high flow rates thanks to large equivalent cross-sections of 2.8 to 34 mm².
- The NBR O-ring ensures reliable sealing in a wide range of applications.
- The AKH check valve is equipped with a plug-in connection and an external thread. The versions with R thread are also equipped with Teflon tape.
