Lubricated Plug Valve Manufacturer in Europe – Valvesonly Europe (Germany) 

Valvesonly Europe is a trusted Lubricated Plug Valve Manufacturer in Germany, supplying robust metal-seated valves for high-pressure, high-cycle industrial service. Our lubricated plug valves are built to API 6D, API 599, ASME B16.34, and PED 2014/68/EU standards, with precision machining, advanced sealing technology, and full 3.1/3.2 material certification. Each valve is hydrostatically and seat-tested to API 598 / EN 12266-1, ensuring leak-tight performance even under severe operating conditions. 

 

Function & Working 

A lubricated plug valve uses a tapered or cylindrical plug that rotates inside the valve body to control flow. Sealant lubricant is injected between the plug and body to provide a tight seal, reduce torque, and protect sealing surfaces from wear. This design is especially suited for services where solids or impurities could damage conventional seats. 

The lubrication film also acts as a corrosion inhibitor and allows the valve to operate smoothly in high-cycle or abrasive applications. 

 

Advantages 

  • Positive Metal-to-Metal Sealing: Lubrication film ensures zero leakage. 
  • Low Operating Torque: Even under full differential pressure. 
  • Long Service Life: Sealant protects seating surfaces from wear and corrosion. 
  • Pressure-Balanced Plug Design: Reduces operating load and wear. 
  • Adaptability: Ideal for abrasive, corrosive, or high-temperature service. 

 

Types Offered 

  • Pressure Balanced Lubricated Plug Valve 
  • Twin Seal Lubricated Plug Valve 
  • Jacketed Lubricated Plug Valve
