OEM professional custom pneumatic slide gate valve/pneumatic valve
Product description
Used for shut-off in flue gas line of dense and sticky dust.
It consists of casing, blade, shaft, gland packing, sealing
mechanism and actuators.
Normally the blades are moved same distance of duct diameter for
shut-off.
For shut-off method, by only packing, by using fastening bolts, by
seal air or fastening cam.
Moving the blades, by wire rope, by chain block, or using power,
screw-rod, chain, wire rope, cylinder rod, etc.
Specification
1. Materials: Carbon steel, stainless steel;
2. Different size from 200x200mm to 500x500mm;
3. There is manual, electric and pneumatic actuators.
It is an ideal equipment to control dust material flow. It is
mainly composed of frame, screw nut, hand wheel, chain wheel, disc,
turn the hand wheel(chain), screw with the screw nut and damper for
the reciprocating movement of horizontal direction, opening and
closing of the valve.
Feature
normal: metal touch / high close: packing
Minimize the width of damper.
No stick-out of blades in the duct upon open and shut motion.
Ensure the smooth open and shut.
By using the simple blade construction, minimize the distortion of
blades by heat and ensure the smooth open and shut and apply the
dust removal mechanism for high dust application.
(in case dust accumulation is foreseen, necessary to install
cleaning hole and dust hopper)
Realize complete shut-off by using elastic seat and seal air.
Open blade type, possible to check the conditions of the blade
(such as distortion, erosion, etc.) upon full open.
Application
Air or Gas Duct in Boilers, Gas turbines for power generation,
Incinerators, Iron & Steel Plant, Cement Plant, Glass Making Plant,
Oil Refinery, Deodorization Plant, Marine Boilers, etc.
