Valve is to control the media flow and circulation opening and closing pieces, the entire valve structure plays a vital role, it can also be passed through a turbine lever operated, pneumatic, electric and other equipment operation. The quality of valve determines the overall performance of the valve, the valve seat in contact with the plastic surface of the formation determines the degree of tightness of the valve or bad.
     Stainless steel butterfly plate is divided into two kinds of material, 304 and 316 # stainless steel. 304 because of its good ductility, cold forging processing performance and good corrosion resistance, stainless steel products become the most widely used types of steel, 316 because adding a metal molybdenum, have a good resistance to reducing media and pitting corrosion, especially in seawater media, corrosion resistance than 304 strong! Flap valve materials are: ductile iron, stainless steel, aluminum, bronze, etc.
Valve flap structure are: Through shaft without pin, midline and double axle, etc.
Colors are: silver, bronze, red, blue, etc.
Size: 2 "-24"
