Manual Flat Gate Valve Of Power Station Valves - China

price: 300.00 Dollar US$

Product overview
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 equipment.
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 working principle
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 erosion.
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.
