Z644Tc-10Q double-disc air-lock wear-resistant ceramic
discharge valve (Type AB)
(Warning: The products
are proprietary and patented, and unauthorized reproduction will
be prosecuted，Patent No：ZL02262821.5)
(Our company has passed ISO9001：2000.) |
|  The valves are mainly used
for opening and closing of charging and discharging of gas and
slag in dry ash system of power plant, and also applicable for
opening and closing of such media as wear and corrosion-resistant
fine dust, water, oil and vapor at tube edge in the industries
of mining, paper-making and petrochemical etc. PG double-disc
air-lock wear-resistant ceramic valve has the advantages of good
sealing property, high temperature resistance, strong wearability,
easy starting, no ash deposit and long service life.

Installation instructions to bleeder valve：
Welcome to select the patented products of our company.
In order to prolong service life and improve operating efficiency,
this valve should be installed as vertical as possible, and if
the conditions do not allow the installation should be carried
out in 45°. For upside-down or horizontal installation, the idle
conveying time must be extended so as to avoid ash accumulation
in valve. In this valve the return signal adopts imported inductive
magnetic switch two-wire system, and the signal line can adapt
to both DC and AC via load. “Refer to the figure for installation
of signal line”
Operating instructions
1、Before installation this instruction should be
carefully read, and type, full bore and technical parameters of
the valve be checked.
2、After installation of valve welding flange is
forbidden to prevent from damaging the seal ring of valve. The
installation distance for valve reserved in pipelines shall be
appropriate, and gaskets shall be added on both sides of flange.
3、The centers of two pipelines shall be remained
coaxial with the center of valve full bore, and two sides of flange
shall be smooth so as to guarantee clamping and normal operation
of valve. |
