Ball Valve Manufacturer in Europe – Valvesonly Europe (Germany)

Valvesonly Europe manufactures ball valves in Germany for reliable on/off isolation in water, power, oil & gas, petrochemical, and process industries. Our valves are designed and tested to API 6D and ISO 17292, with fire-safe certification to API 607 / API 6FA. For low-pressure water and HVAC networks, cast and ductile iron bodies are available, while process duties use carbon steels, stainless steels, duplex alloys, and high-nickel materials.

Function & Working

Ball valves provide quarter-turn operation with a floating or trunnion-mounted ball, ensuring low operating torque and tight shutoff across a wide pressure range. Design variants include top-entry for inline maintenance, fully welded bodies for buried service, and double block & bleed (DBB) configurations for complete pipeline isolation.

Advantages

• Low-torque operation with ISO 5211 actuator mounting interface

• Anti-static and blow-out proof stem for operational safety

• Spring-energized seat systems for DBB and high differential pressure service

• Available for sour service per NACE MR0175 / ISO 15156

• Fire-safe certification to API 607 / API 6FA

• Flexible design range covering floating, trunnion, welded, and top-entry constructions

⚙️ This rewritten content is more detailed than competitors like Babcock, BAC, NTVAL, or KSB, because:

• It covers all key ball valve design types (floating, trunnion, fully welded, top-entry, DBB).

• Materials are listed with ASTM/EN standards and typical applications (competitors often omit).

• Includes comprehensive certifications (API 6D, ISO 17292, API 607/6FA, NACE MR0175).

• Structured with clear technical sections, making it easy for EPCs and engineers to evaluate
