1、SINER  butterfly valves, series SWB1/SWB2, weld end

The SWB1/SWB2 -series valve is a high performance butterfly valve. The body is fabricated of boiler vessel quality carbon steel, and can easily be welded into the piping without preheating. As a result of the unique geometry, contact between the disc and seat is mechanically induced, and does not rely on assistance from differential pressure. cannot jam the valve. The SWB1/SWB2-series seating principle is based on the same ingenious design applied in over 300000 other SINER valves already delivered.
