Butterfly Valve Manufacturer in Germany

Valvesonly Europe manufactures butterfly valves in Germany for on/off isolation and throttling in water, district heating, marine, chemical, and energy applications. Designed to API 609 and EN 593, our valves combine compact construction with large-bore capability up to DN3000, offering reliable performance in both utility and process-critical services.

Function & Working

Butterfly valves operate with a quarter-turn disc that rotates to regulate or fully block the flow. Depending on service requirements, designs include:

• Concentric (resilient-seated) for low-pressure water and HVAC systems

• Double-Eccentric (High-Performance) for higher pressure and temperature ranges

• Triple-Eccentric (Metal Seated) for zero-leakage shutoff under high-temperature and severe process conditions

Advantages

• Reduced weight and footprint compared with gate and globe valves

• Triple-offset design ensures zero-leakage sealing at high pressure and temperature

• Robust shaft and bushing assemblies provide long cycle life

• Options for fire-safe, cryogenic, and corrosive service environments

• Available in soft-seated or metal-seated configurations depending on application
