At YLOK Fluid, we have been producing vacuum-insulated transfer systems for cryogenic liquids (LNG, LH2, LOX, LN2, LAR) since 1984. Since 1990, we have expanded our range of services to include the manufacture of cryogenic valves. From our factory site in China, we supply many of the world's most renowned companies in industry, high-tech and research.

Since then, YLOK has delivered more than 25,000 pneumatic and manual valves for the control of cryogenic transfer systems. Our valves in sizes from DN6 to DN250 are certified according to ADR/RID 2021 and approved for the transport of media by road in accordance with Directive 2010/35/EU (TPED).

Functions: Shut-off valve, control valve, non-return valve

Nominal sizes: DN6 to DN250

Pressure ratings: Depending on type up to PN400

Types of construction: Straight, angled and Z-shaped passage

Actuation: Manual or with pneumatic diaphragm actuator

Groundbreaking developments

The development of valves for cryogenic applications has the task of ensuring minimal energy losses and excellent insulation during media transport. YLOK masters these challenges through intensive research and development and continues to find new solutions that meet the specific requirements of different applications.

One of YLOK's pioneering developments is the introduction of an electrically driven valve for liquid hydrogen, the innovative technology of which goes far beyond conventional pneumatic valves. In addition to highly precise control of media flows, it offers considerable advantages in terms of efficiency, cost optimisation and safety.

Comprehensive service

In addition to production, we at YLOK cover the entire range of services from simulation technology and engineering to material testing and the installation of our systems, documentation and other services. Our aim is to play an active role in shaping the mobility of the future and to drive forward the development of sustainable technologies.
