Product introduction
HB2416 pneumatic piston 3-eccentric butterfly control
(shut-off) valve is independently developed by our company for
practical working conditions in industries and aiming at solving
the sealing performance problem of coal gas and high
temperature air. Through times of experiments and
improvements, the technology department confirmed the
eccentric distance and cone angles by applying engineering
analysis and simulation function. CNC machining center is used
for the processing of conical surface of body and discs and the
assurance of axle hole and eccentric precision, which greatly
improved the precision and credibility. The quality accessories
such as actuator and positioner ensure the proper run of control
valve on site..

Product characteristics and advantages
The first eccentric “a” of 3-eccentric structure is formed by the axle deviating from the central line
of sealing surface. The second eccentric “b” is formed by the axle deviating from the central line
of pipeline. The goal of these two eccentrics is to reduce the friction between seat and sealing
surface. The third eccentric “c” is an eccentric angle β, which uses the cam effect to realize the
no-friction contact between seat and sealing ring of disc during the 90° travel of valve, thus to
avoid the probability of wear and leakage.; when closing the valve, the sealing pair will close
gradually to cause “wedge effect” and to realize the tightest shut-off with the smallest torque.
