Eccentric Rotary Plug Control Valve

UTMOST eccentric plug valve has the outstanding advantages of simple structure, small volume, lightweight, strong flow capacity, wide adjustable range, wide service temperature range, small leakage, good stability, low valve cost, and long service life.

The sealing form of the eccentric rotary control valve is hard-seal, which is connected with a pneumatic actuator, matching positioner, solenoid valve, and other accessories to realize proportional adjustment.

Eccentric Rotary Plug Control Valve Working Principle

The working principle of the eccentric rotary plug control valve is a fan-shaped ball valve with eccentric rotation. The eccentric ball core is tangent to the valve seat, and when it is opened, the spool is separated from the valve seat. When closed, the spool gradually confects the seat of regulating valve types , so that the ball exerts a pressing force on the valve seat. The eccentric rotary valve has a simple flow path and low resistance.

Eccentric Rotary Plug Control Valve Structure Feature

Compared with single and double seat valves with the same caliber, eccentric rotary plug valve has a larger flow capacity, but its weight is only about 1/3. The spool and the main shaft only rotate, so the friction force it bears when the switch rotates is very small. The flexible arm of the eccentric rotary valve spool produces small elastic deformation and elastic tension under the thrust of the actuator, which makes the contact between the spool and the valve seat more close and firm, so the leakage of the eccentric rotary control valve is very small. At the same time, the thrust required to close the valve is smaller than that of the ball valve and butterfly valve.

As a valve manufacturer, Utmost owned a complete process line from machining, assembling, and testing process. Every Utmost designed product with good performance of high or low temperature, corrosion, and high-pressure resistance.
