Gate Valve Manufacturer in Germany – Valvesonly Europe

Valvesonly Europe manufactures gate valves in Germany for reliable isolation in pipelines across water, steam, oil, gas, and chemical services. Our valves are built to international standards including API 600, API 602, API 603, and EN 1984, with full PED compliance. Cast iron and ductile iron variants are also available for water distribution and district heating networks.

Function & Working

Gate valves operate with linear motion of a wedge, slab, or parallel disc to achieve full flow isolation. The precision-lapped seats and optimized wedge geometry ensure bubble-tight shutoff with reduced galling. Designs are engineered for low pressure drop in the open position, making them suitable for both general and high-pressure services.
