Product Features

1. Adopting a three eccentric sealing structure, the valve seat and butterfly plate have almost no wear, and have a sealing function that becomes tighter and tighter as viewed

2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperature conditions, with characteristics such as corrosion resistance and long service life

3. The sealing surface of the butterfly plate is made of welded cobalt based hard alloy, which is wear-resistant and has a long service life

4. The large-sized butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance

5. Metal hard sealed butterfly valve has bidirectional sealing function, which is not limited by the flow direction of the medium or the spatial position during installation, and can be installed in any direction

6. The drive device can be installed in multiple stations (rotated 90 ° or 180 °) for easy user use

Installation precautions:

1. Before installation, check whether the specifications, pressure, temperature, and corrosion resistance of the butterfly valve meet the requirements for use. Each component should be checked for damage or looseness.

2. This butterfly valve can be installed on pipelines at any angle and should be closed for installation; When welding pipeline flanges, the valve sealing port should be blocked with a plate to prevent particles and debris from damaging the sealing surface. After welding, remove the valve, clean the valve sealing surface and pipeline cavity, and then install and fix the valve.

3. Please pay attention to the direction of pressure when the valve is closed during installation.

4. Before installation, the sealing surfaces (end sealing surfaces, butterfly plate sealing surfaces, valve seat sealing surfaces) should be wiped clean to remove dust and dirt.

5. Before installation, the butterfly valve should be air tested, and its opening and closing should be flexible, with the opening and closing positions consistent with the pointer indication.

6. Manually operate clockwise to close, counterclockwise to open, and do not apply force to open or close the valve after the pointer indicates in place.

7. When conducting pressure tests on valves, it is not allowed to use a single flange for installation and pressure testing. Double flange installation and pressure testing must be used. The test pressure should comply with the GB/T13927-92 standard.

8. When tightening bolts, they should be tightened symmetrically and alternately, and it is not allowed to tighten them separately in sequence.

9. The limit screw has been adjusted before leaving the factory and should not be easily adjusted. If the driving device is configured as electric or pneumatic, please refer to the accompanying driving device manual.

10. The opening and closing stroke of the control mechanism of the electric butterfly valve has been adjusted before leaving the factory. To prevent directional errors when the power is turned on, users should manually turn it on to the half open position before the first power is turned on, and then press the jog switch to check that the direction of the indicator wheel is consistent with the direction of the valve opening.

11. If abnormal valve opening and closing is found, the cause should be identified for repair and elimination to prevent valve damage caused by using force to open and close the valve.
