Features:
The structure is convenient for maintenance, without the need to disassemble the whole from the pipeline.
The valve disc in the open state is hidden in the valve cavity to prevent the medium from directly washing the sealing surface
The valve circulates in the whole flow channel, reducing energy loss, and the head loss is almost zero.
The valve seat is specailly treated, and the sealing surface can meet the requirements of anti-corrosion, wear resistance and high strength.
