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.
