As our primary supplier, Herose GmbH’s quality management system was introduced in 1991 and is certified by TÜV according to DIN EN ISO 9001:2000. This endorses our quality policy "From design through delivery to the customer and beyond."

At goods receipt, all incoming components and materials are inspected in accordance with our documented quality plan. Prior to assembly, all pressure contained parts are tested for strength and tightness, and during the final check every single valve, 100%, is checked thoroughly for function and tightness before delivery.

This assures that valves from all our suppliers are always optimally suited for safe use with the media under the design conditions. We at Herose Limited as a distributor take on the importance of quality management and have our own procedures and approvals in place which can be viewed from this page. Not only can we state we are ISO 9001:2015 approved, but we also have in place Module D approval in line with the pressure equipment directive.

We pride ourselves on knowing that all parts that leave our premises are of the utmost quality and will more than meet your expectations in the field. We focus hard on our quality… so you don’t have to.

(Please note that Correct selection and use are critical.)
