Non lubricated sleeved plug valve manufacturer in Germany

Non-Lubricated Sleeved Plug Valve Manufacturer in Europe – Valvesonly Europe (Germany)

Valvesonly Europe manufactures non-lubricated sleeved plug valves for clean and corrosive services requiring bubble-tight performance with minimal maintenance. Built in Germany to API 599 / ASME B16.34 / PED.

Function & Working

Advantages

Maintenance-free sealing; no external lubrication

Tight shut-off in both directions

Low torque; excellent chemical resistance

Fire-safe versions with secondary metal seat

Full-bore and reduced-bore configurations

Types Offered

Full Bore • Reduced Bore • Fire-Safe • Jacketed
