Lubricated plug valve is a valve that trough 90°rotation to make the access of the valve plug and the body same or separate to achieve the opening or closing. Lubricated plug valve is suitable for flow cutting and switching or shunt, and sometimes can be used for throttling according to the characteristics of medium and erosion resistance of sealing surface. In order to reduce the friction between the body and the plug sealing surface. The lubricated plug valve is generally the grease lubricated seat sealing structure. Ordinary spur drive lubricated plug valve is sealed by contacting the metal plug body and the valve body directly.
We are a fully stocked manufacturer and supplier of lubricated plug valve and we make the valve easy to find for your need.

Please review the charts below for available sizes & pressure & material or fill the contact form below.
- Simple structure, quick switch and low fluid resistance;
- The lubricated plug valve usually use the rectangular flow path to reduces the torque while increases the fluid resistance;
- The sealing surface of the cone and valve body is ground with lower opening and closing torque;
- STL alloy material or surface hardening technology can be surfacing in the cone seal of the cock to enhance the wear resistance and corrosion resistance of the sealing surface, with long service life.
