afety Valve Manufacturer in Europe – Valvesonly Europe (Germany)

Valvesonly Europe is a leading Safety Valve Manufacturer in Europe, with our advanced manufacturing facility located in Germany. Our safety relief valves are engineered to provide reliable over-pressure protection for critical systems, ensuring compliance with global standards such as EN ISO 4126, API 526, and ASME B16.34. Each valve is precision-designed, set, and tested in Germany under stringent PED categories and modules, guaranteeing safe operation across industries handling steam, gas, liquids, and cryogenic fluids.

Function & Working

Safety valves are designed as spring-loaded or pilot-operated devices that automatically relieve excess pressure when the system exceeds its set point. The integrated blowdown ring mechanism ensures precise, stable reseating, maintaining system safety while minimizing product loss. For specialized applications, valves are available with oxygen-clean service preparation and extended bonnets for LNG and cryogenic duties.

Advantages

Precise blowdown control for gases, steam, and liquids
High-temperature metallurgy and nozzle ring designs for stability under extreme service
Special preparation available for oxygen and clean gas service
Cryogenic bonnet extensions tailored for LNG and low-temperature duties
German-engineered with full material traceability and PED/CE compliance

Types Offered

Spring-Loaded Safety Valve – simple, reliable design for steam, gas, and liquid services
Pilot-Operated Safety Valve – precise control for high-pressure and large-capacity duties
Conventional Safety Valve – economical design for stable operation under standard backpressure
Balanced Bellows Safety Valve – compensates variable backpressure for consistent performance
Cryogenic Safety Valve – extended bonnet configuration for LNG and ultra-low temperature service
