FREE-ValvesPneumatic
Ceramic Double Disc Gate Valve is mainly used in feeding and
dumping the dry powder and the transport pipeline, which not only
adopt toughening ceramic as shut off and wear out resistance
material, but also design construction of pressure self-sealing and
valve disc auto-rotate, so as to the sealing surface within the dry
powder get more wear resistance in process of opening and closing
frequently, thereby, which guarantee the high requirements of
sealing performance of this valve and long working
time. Features: 1.Sealing
pair is made of structural ceramics,which
have perfect performance to resist wear and
flushing. 2.Two-side
sealing can realized due to doublediscstructure
of the pneumatic ceramic double disc gate
valve. 3. It inserts spring between double valve
discs to ensure self- sealing through bi-directional flexible
preload pressure of spring, having characteristics of low
pressure bi-directional sealing and without dust clogging
phenomenon in the process of the opening and closing of
valve. 4.The
valvedisc rotational
motioncan avoid
the ash deposition on the sealing
surfaceduring opening
and closing, so the
valves have much longer service. 5. The blow sweep port or automatic blow sweep
device can be set on the valve body according to different
operating conditions. Technical
