| Z644Tc-10Q double-disc air-lock wear-resistant ceramic
equalizer valve
(Warning: The products
are proprietary and patented, and unauthorized reproduction will
be prosecuted，Patent No：ZL03278197.0)
(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. |
