FABIA Pneumatic Flue Flapper Valve Stainless Steel Flue Flapper
Valve
1. Description:
Gas baffle valve is mainly used in the inlet, outlet or bypass flue
of the absorption tower of the flue gas desulfurization system to
isolate the flue gas flow, and can also be used in other flue gas
pipelines with high operational isolation requirements, with no
internal leakage and leakage after closure, good sealing, no air
leakage and leakage phenomenon.
High temperature does not deform, does not accumulate soot, the
switch is flexible during normal operation, no jam phenomenon, low
resistance, hydraulic drive, high stability.

3. Features:
- Normal operation is driven by hydraulic pressure, the pressure can
reach 20 MPa, the thrust can reach more than 17 tons, the tension
can reach more than 13 tons, the power is large, the flexibility to
overcome the resistance is strong, the switch is flexible, no jam
phenomenon, and the stability is high.
- Combination of soft seal and hard seal, soft seal for high
temperature silicone plate, hard seal for 316L stainless steel
plate special track, no internal leakage or external leakage, to
ensure zero leakage, 100% air tightness, and increase the sealing
when necessary.
- Switch position can realize the remote transmission of electrical
connection. Field control box with position indication. The power supply adopts the original power supply of the
distribution room. At the same time, it can be remotely connected to the DCS control
system of Party A to achieve local and remote control, and the
on-off signal can be connected with the DCS.
- Factory is equipped with oil cylinder, oil station, electric
control box, a complete set of two-way anti-flange, and connected
with the valve by bolts, and the gap seal is the disc seal. After arriving at the site, the flange can be welded directly to
the field flue, simple installation, short cycle, can be completed
in a small maintenance period.
- Open state: the insert plate is outside the flue, avoiding the
corrosion of high temperature smoke and medium, which not only
reduces the resistance of the smoke circulating in the flue, but
also ensures the service life of the insert plate. Closed state: The insert plate is made of carbon steel, lined on
both sides with 316L stainless steel plate or other corrosion
resistant steel plate to ensure the service life of the valve.
