Based in Guildford, Surrey, Herz Valves UK Ltd has been serving the UK for around 40 years. The parent company, Herz-Armaturen, is based in Vienna Austria and was founded in 1896.

Herz manufactures an extensive range of quality-engineered valves and controls for heating and cooling systems.

Herz operates a pro-European manufacturing policy and has seven factories located within the EU. Quality is important at Herz and is easily controlled, since all manufacturing units can be reached within two hours. This provides advantages for supply chain management, and finished products can reach the UK within one week.

In the early 1960s, Herz-Armaturen established a quality assurance system that enabled the company to grant a five-year warranty for all products. This warranty is still valid for all products specified in the Herz Certificate of Guarantee, ensuring high production standards and reliable products.

All work at Herz is done in accordance with an up-to-date quality management system certified according ISO 9001 and numerous national and international certificates cover entire product range.
