Manual flat gate valve Z43F - 16 c is suitable for natural gas,
petroleum, chemical industry, environmental protection, city
pipeline, the gas pipeline conveying pipeline, such as steam vent
system and the storage device, used for opening and closing device.
This series product adopt new floating type sealing structure, is
applicable to pressure is not more than 10 mpa, temperature - 29 ~
121 degree centigrade on the gas pipeline of H2S gas content is
higher, as control opening and closing of the medium and adjusting
device, the product structure design, select material appropriate,
strict testing, convenient operation, strong corrosion, wear
resistance, erosion resistance, is a kind of ideal new oil industry
Manual flat gate valve Z43F-16C Scope of application:
Flat gate valve is suitable for natural gas, petroleum, chemical
industry, environmental protection, city pipeline, the gas pipeline
conveying pipeline, such as steam vent system and the storage
device, used for opening and closing device.Z43 diversion hole
Single valve plate Flat gate valve Suitable for gas drilling and
purification Long distance pipeline .
Manual flat gate valve Z43F-16C Structural characteristics and
1, adopt the floating seat, two-way opening and closing, reliable
seal, flexible opening and closing.
2, valve plate are oriented to give precise guidance, at the same
time, sealing surface spraying weld hard alloy, resistance to
3, high carrying capacity of the valve body, the channel for
straight-through, fully open, and valve plate similar diversion
hole through and straight pipe, the flow resistance is very
small.Stem with composite packing, multiple seal, make reliable
sealing, low friction.
4, close the valve, rotating the handwheel clockwise, valve plate
down to the bottom, due to the effect of medium pressure, will be
imported into the valve end seal seat plate direction, form a
larger sealing pressure, thus forming the first line of the seal.At
the same time, the valve plate to the outlet pressure sealing seat,
become a double seal.
5, due to adopt double seal, so can work without affecting pipeline
under the condition of replacement parts.This is our factory
product prior to the important characteristics of similar products
at home and abroad.
6, open the valve plate, the handwheel counterclockwise, valve
plate up, diversion hole with channel pore penetration.As the valve
plate, the rise of the communicating pores increase gradually, to
limit position, diversion holes collocated with the channel holes,
fully open at this time.
