Lubricated Carbon Steel Plug Valve

NSV Lubricated Carbon Steel Plug Valve

The NSV lubricated carbon steel plug valve is specifically engineered for non-corrosive or mildly corrosive industrial fluids. Cast from WCB or LCB carbon steel, it delivers excellent mechanical strength and pressure containment.

A sealing lubricant is injected to form a dynamic oil film between plug and body, ensuring reliable sealing up to Class 900 while significantly reducing operating torque.

 Available with manual, electric, or pneumatic actuation, it offers fast, smooth operation and easy maintenance—making it the ideal cost-effective solution for critical on/off service in oil & gas, power, and pipeline applications.
