Check valves for high-tech applications

Quality features

HT check valve models are made of special materials approved for use with potable water. The black polymer is furthermore characterized by its good resistance to, for example, anti-freeze and chlorine compounds.
In continuous operation, these check valves are suitable for up to 127 °C (260 °F) or 130°C (266 °F) depending on the material.
The valves are certified according to DIN EN 13959 and ASME A112.18.3

Selection criteria

Please note that HT check valves are only available for our OEM/industrial customers. For more details, as well as information on worldwide approvals, please see the product listing. To refine your selection, please use the following points as filters.

Bore diameter: The shape of the check valve and the outer diameter determine the diameter of the mounting bore. These dimensions are essential to ensure precise installation in the bore.
Flow rate: Instead of a specific value, there is a flow rate range in liters per second (l/s) for each model.
Design: Open
Max. application temperature: 127 °C (260 °F) and 130°C (266 °F) respectively in continuous operation.
Spring: Certain models are available with a strong spring that meet the 7 kPa closing pressure recommended by Australian plumbing standards according to AS/NZS 2845.
