Eccentric Plug Valve
Eccentric plug valve is a valve with excellent flow regulation performance. It is composed of a valve body, plug, bearing, sealing ring, actuator, etc. Its structural feature is that the valve plug is eccentrically installed on one side of the valve body centerline. This structure can form an eccentric space when the plug rotates, thereby achieving the purpose of flow regulation.

Products Description
Eccentric plug valve's unique eccentric seal design significantly reduces operating torque compared to traditional plug valves, minimizing wear on the sealing surface and extending the valve's service life. Its rectangular, straight-through flow path minimizes head loss and provides excellent flow regulation linearity. This plug valve is suitable for use as a shutoff or regulating device in environments such as municipal sewage, industrial wastewater, slurry, and clear water.
Eccentric Plug Valve Features
1. Double eccentric design, low-friction opening and closing, ensuring zero leakage
2. 90% nickel-containing, 3mm-thick welded valve seat or high-performance resin valve seat, meeting various corrosion resistance requirements
3. V-shaped combined seal ring, replaceable without removing the operating device
4. Sealant filling port extends the valve's service life
5. Self-lubricating valve bearings, eliminating the need for grease and causing minimal wear on the valve shaft
6. Molded hot-dip overmolding of the plug body eliminates concerns about rubber loss and erosion corrosion
7. O-rings seal the valve bonnet and body, reducing the number of bolts and facilitating maintenance
8. Pressure gauge connections are provided for the valve's inlet and outlet for convenient flow control and measurement.
Functions of Eccentric Plug Valves
1. Flow Control: Eccentric plug valves can adjust fluid flow by rotating the valve body, offering a wide adjustment range to meet the needs of various applications.
2. Shut-off: When shutting off fluid flow, the valve can be rotated to the closed position to shut off the flow.
3. Excellent Sealing Performance: The eccentric plug valve utilizes an eccentric double-eccentric structure, ensuring a tight seal in both open and closed positions.
4. High Wear Resistance: The valve is made of high-hardness, high-strength alloy steel and undergoes a special treatment process to significantly enhance its wear resistance.
