Double Diaphragm Ceramic Gate Valves
Function and utility
This valve
is used to control open and close of
dust conveying pipeline
s
install
ed
in thermal power generation, papermaking, steel, coal chemical industr
ies
and so on. Applicable mediums: dry ash, dust and lime-ash.
Working pressure 0.6MPa-1.6MPa, working temperature
≤
180
ºC
, air pressure 0.4MPa-0.6MPa
The valve should be installed horizontally with the non-sealed surface facing down
Performance characteristics
1.
This valve is suitable for conveying pipelines, and it is used as one of the effective valves in controlling bin pump inlet. Using the latest
ZTA
composite industrial ceramic, this valve has a hardness of HRC
>=
90 with high toughness, thus solving the problem with the crisp of ceramics. In operation, the valve plate rotate
s
automatically with the up-and-down motion. And the self-grinding between valve plate and seat can prolong the service time of the valve. The designed ash slope under the valve and the purging device in the middle valve body can eliminate the phenomena of ash blocking, jam and obstruction,
thus to
ensure the normal operation of the valve.
This valve applies to the size of DN300, DN250 and DN200.
We can also provide customized non-standard valves according to our customers' demands.
