ZF63Y Butt Welding High Pressure Flat Gate Valve Product Description

ZF63Y Butt Welding 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, closing and adjusting devices of control media such as oil and natural gas with the pressure less than 40MPa and the temperature not higher than 120 ℃. The product is of novel design and proper material selection , Strict testing, light operation, with strong anti-corrosion, wear resistance, erosion resistance, the oil and gas industry is an ideal new equipment.

ZF63Y Butt Welding High Pressure Flat Gate Valve structural characteristics and working principle

1, the use of floating seat, two-way opening and closing, reliable sealing, opening and closing flexible.

2, the lower part of the gate open diversion hole, and to give precise guidance, while the seal are sprayed  Carbide welding, erosion-resistant. High-pressure hard-sealed welding flat gate valve

3, the body carrying capacity is high, the channel is straight-through, fully open, and the gate diversion hole  Similar phase-through and straight pipe, flow resistance is small. Stem at the composite filler, multiple seals, making the seal reliable, small friction. Futai Oilfield valve experts

4, closing the valve, turn the hand wheel clockwise, the gate moved to the bottom, due to referral  The role of quality 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 double seal, it can be in the pipeline does not affect the work even more  For wearing 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 holes and channels  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. Oilfield pipeline flat gate valve

ZF63Y Butt Welding High Pressure Flat Gate Valve performance specifications

ZF63Y Butt Welding High Pressure Flat Gate Valve use, maintenance, care and precautions

1, the valve has been made before the factory strength and seal test, all connections should be used to maintain the initial state.

2, this series of valve operation handwheel marked with the opening and closing rotation signs, the upper rod with open and close the height of the rod, for the regulation instructions.

3, the valve and pipeline welding, the valve should be opened, the proper use of wet material to protect the neck, minimize heat conduction, to prevent damage to the seal pieces. Forté high-pressure flat gate valve

4, closed the valve is forbidden to use the force lever, the gate closed to the top of the hand wheel should be rotated ½ turn so that the gate in a floating state.

5, the valve in use, as a result of wearing parts and leakage, should be promptly replaced. 0577-67354191

6, the valve in the overhaul process, the cavity should be cleaned, the assembly should be the transmission parts plus grease.

7, valve storage is disabled, the gate should be in the closed position, long-term deposit
