Our Shop

Valvesonly Europe is a leading Plug Valve Manufacturer in Europe, based in Germany, delivering high-performance solutions for tight shut-off and flow control. Our plug valves are engineered with conical or cylindrical plugs that rotate inside the valve body, providing bubble-tight sealing, quick operation, and low pressure drop. Designed in compliance with API, ASME, and EN standards, our plug valves are widely used across oil & gas, petrochemical, chemical, power, and water treatment industries.

Function & Working

Plug valves work by rotating a tapered or cylindrical plug with a through-hole inside the valve body. When aligned with the pipeline, the flow path opens; when rotated 90°, the plug blocks flow completely. Available in lubricated, non-lubricated, and jacketed designs, they ensure smooth operation, corrosion resistance, and long service life under demanding conditions.

Advantages

• Quick 90° operation with minimal torque

• Compact & lightweight body for easy installation

• Full port & reduced port designs available

• Zero leakage sealing with PTFE, graphite, or metal seats

• Fire-safe, anti-static design for critical oil & gas duties

• Easy inline maintenance with replaceable seats and seals

Types of Plug Valves Offered

• Lubricated Plug Valve – Uses sealant to reduce friction and prevent leakage in high-pressure services

• Non-Lubricated Plug Valve – PTFE or elastomer sleeves provide sealing without lubrication

• Jacketed Plug Valve – Maintains media temperature for viscous fluids like bitumen, sulfur, or polymers

• Eccentric Plug Valve – Quarter-turn, non-binding operation for wastewater, slurry, and abrasive duties

• 3-Way & 4-Way Plug Valve – Multi-port flow diversion and mixing applications

• Lift Plug Valve – Plug lifts during operation to minimize seat wear and provide extended service life
