The electric soft-seal butterfly valve is an electric valve that uses a circular butterfly plate that rotates with the valve stem to open and close. It is mainly used as a shut-off valve. The soft-seal butterfly valve has a simple structure, small size, light weight, low cost, easy operation, and can also adjust the flow medium. The fluid resistance is small, and the medium and large diameter electric butterfly valve has a large effective flow area when fully opened. The opening and closing are quick and labor-saving. The butterfly plate can be rotated 90 degrees to complete the opening and closing. Good sealing can be achieved under low pressure. The butterfly valve sealing materials include nitrile rubber, fluororubber, edible rubber, and PTFE lining, so the sealing performance is good. Among them, the hard-sealed butterfly valve is a soft and hard laminated metal sheet with the advantages of metal hard sealing and elastic sealing. It has excellent sealing performance regardless of low temperature conditions.
