H+VALVES – Pressure Safety Expertise for Over 40 Years

Welcome to H+VALVES!
For more than four decades, H+VALVES has supported industrial players by protecting people, the environment, and installations against pressure-related risks. As a designer and manufacturer of safety valves, we serve a wide range of industries—from chemical to nuclear, food processing to pharmaceuticals, industrial gases to cosmetics.

Recognized Technical Know-How
Founded over 40 years ago, H+VALVES has established itself as a trusted name in pressure safety. Since 2006, our integration into the TECHNE Group has strengthened our innovation, industrial capacity, and international presence, while preserving our agility and close customer relationships.

We design and manufacture our valves in France, in our production site in Pommiers, near Lyon, in the heart of one of Europe’s leading industrial regions.
This strategic location allows us to combine French engineering excellence with efficient logistics for customers worldwide.

At Pommiers, we control the entire process — from design and machining to assembly and testing — ensuring each safety valve meets the highest standards of reliability, compliance, and traceability.

Tailored Solutions for Every Application
We offer a comprehensive range of safety valves, adapted to all types of fluids (gases, liquids, steam), pressure ranges, and demanding environments:
– Process safety valves for standard industrial equipment
– Thermal expansion valves to manage pressure increases due to temperature variations
– Tank breathing valves for managing pressure in tanks and storage vessels

We cover low to high pressure ranges and work with materials suited to each application: stainless steel, carbon steel, bronze, cast iron, Hastelloy®, and more.

Cross-Industry Expertise
Our valves are used in sectors where safety and compliance are critical:
– Chemical and petrochemical industry
