ZF43Y Flange High Pressure Flat Gate Valve product details

ZF43Y Flange High Pressure Flat Gate Valve product introduction

ZF43Y Flange High Pressure Flat Gate Valve produced and sold by Baigang valve group, This series of products adopt the new balanced floating seal structure, which is suitable for the opening and closing and adjusting device of control medium, such as water, oil, natural gas and so on, whose pressure is not more than 40MPa and whose temperature is not higher than 120 ℃. The structure of the product is novel in design It is an ideal new type of equipment for petroleum industry with proper material selection, rigorous testing, light operation and strong anti-corrosion, wear-resistant and erosion-resistant properties.

ZF43Y Flange High Pressure Flat Gate Valve structure characteristics and working principle
1, the use of floating seat, two-way opening and closing, sealing and reliable, opening and closing flexible.
2, the lower part of the gate opened a diversion hole, and to give precision-oriented, while the seal is spray-welded cemented carbide, erosion-resistant.
3, the valve body carrying capacity is high, the channel is straight-through, fully open, and the gate diversion hole through and straight pipe similar to the flow resistance is small. Stem composite filler, multiple seals, making the seal reliable, small friction.
4, close the valve, turn the hand wheel clockwise, the gate moved down to the bottom, due to the role of media pressure, the inlet seal seat to the gate direction. A larger seal than the pressure, thus forming the first seal. At the same time, the gate pressure to the outlet seal seat, a double seal.
5, due to the use of double seal, it can not affect the pipeline work more vulnerable parts. This is our factory product priority over similar products at home and abroad an important feature.
6, open the gate, turn the hand wheel counterclockwise, the gate up, diversion hole and channel hole through. With the rise of the gate, the through hole gradually increases to the limit position, the guide hole coincides with the passage hole, then fully open.
