H+VALVES – Overpressure Safety Expertise for Over 40 Years

H+VALVES designs and manufactures safety valves with the highest levels of quality and reliability — supported by ISO 9001, ISO 14001, ISO 19443, the Pressure Equipment Directive (PED 2014/68/EU), CE compliance, and a 3-year manufacturer warranty.

For more than four decades, we have protected people, the environment, and industrial facilities against overpressure risks, serving industries such as chemicals, nuclear, food processing, pharmaceuticals, industrial gases, and cosmetics.

Recognized Technical Know-How

Founded in 1980, H+VALVES has established itself as a trusted name in pressure safety. Since 2006, our integration into the TECHNE Group has strengthened our innovation capabilities, industrial capacity, and international presence — while preserving our agility and close customer relationships.

We design and manufacture our safety valves in France, in our premises near Lyon — a major industrial hub in southeastern France, close to Switzerland and Italy.
This strategic location enables us to combine French engineering excellence with efficient logistics for customers worldwide.

Within our premises, we control the entire process — from design and machining to assembly and testing — ensuring every safety valve meets the highest standards of reliability, compliance, and full traceability.

Tailored Solutions for Every Application

We offer a comprehensive range of safety valves for all types of fluids (gases, liquids, steam), pressure levels, and demanding environments.

Our solutions cover low to high pressure ranges and are available in materials adapted to each application: stainless steel, carbon steel, bronze, cast iron, Hastelloy®, and more.
