Z644Tc-10Q double-disc air-lock wear-resistant ceramic
discharge valve (Type C)
(Warning: The products
are proprietary and patented, and unauthorized reproduction will
be prosecuted，Patent No：ZL03221432.4)
(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.
|
|
- The body of KR double-disc air-lock wear-resistant
ceramic valve is combined with cast steel, cast iron and wear-resistant
ceramics.
- Service temperature ≤250℃
- The nominal pressure of actuator is 0.4～0.6Mpa
and the nominal pressure of valve is 1Mpa
- customizable according to user’s requirements

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. |
