Pneumatic Actuator Stainless Steel Knife Gate Valve
Application: This gate valve is suitable for opening and
closing or adjusting the flow of various wear and corrosive slurry
and particle pipelines in power plants, mines, papermaking,
metallurgy, chemical industries, etc. The nominal pressure is
0.6-1.6MPa, and the temperature is -40ºC-1000ºC. The sealing
form is divided into three categories: metal hard seal,
wear-resistant ceramic seal, and soft seal, with good sealing
performance. High compressive strength, good abrasion
resistance of the sealing surface, easy installation, flexible
switch, less dust jam and ash formation, and long service
life.Technical Features: 1. The fully circular straight
channel design of this valve does not contain slag or jam. The
bottom end of the valve plate is processed into a knife-edge
shape, which has a cutting function for soft materials such as
fiber, pulp and wood pulp, and has a good opening and closing
function. The valve plate is finely ground and polished to
obtain a better sealing effect. It has compact design, small space
occupation, light weight, low price, easy
installation, perfect wear-resistant and anti-blocking
measures, easy maintenance, convenient use and long life, and
the drive device can be selected arbitrarily.2. The valve body and
packing culvert are all precision castings. The valve body adopts
flange-type integral casting. The material can be WCB, 304,
316, 316L, 2Crl3 according to user needs, and the sealing ring
adopts graphite packing and PTFE reinforced
polytetrafluoroethylene. Vinyl material, corrosion-resistant,
wear-resistant, non-stick slag.3. The valve plate has 5 supporting
points, so that the valve plate has a good
self-centering. When the valve is closed and under back
pressure, the valve plate does not deviate.4. The thin gate valve
can be equipped with handwheel, sprocket, hydraulic, pneumatic and
electric.5. The connection forms of this valve include wafer type
and flange type. The sealing forms include metal hard seal,
wear-resistant ceramic seal, and soft seal. The ceramic seal
and soft seal seat can be disassembled and replaced after wear. It
is convenient for maintenance. At the same time, it also reduces
the user's cost of use.6. Applicable medium: fly ash, gold ore
powder, tailings, paper pulp, wood pulp, fiber, dust, chemical
treatment sewage, sedimentation tank, ore, slag, coal slime,
asphalt, silo outlet, fruit, grain, Cement slurry,
slaughterhouse wastewater, etc. Product Standards: Design
