PRODUCT INTRODUCTION
A plug valve is a shut off or plunger rotary valve that opens or closes by rotating 90 degrees to make the port on the plug connect with or separate from the port on the valve body. Pressure balance lubricated plug valve is a quick switch through valve. Movement between the sealing surface produces wiping effect, but when non-lubricated plug valve is in full open, It canprotection against contact with flowing media. This product is suitable for cutting and switching media, as well as diverging, and it can also be used for throttling due to the erosion resistance of the sealing surface.
PRODUCT ADVANTAGES
The Pressure balance lubricated plug valve is good for frequent operation as it can be open and closed quickly.
Its fluid resistance is lower.
The structure and volume is small and it is light in weight,easy to maintain.
Good sealing performance.
Not limited by the direction of installation. The flow direction of the medium can be arbitrary.
No vibration, little noise.
