Product Name:
Cast Iron Wafer Butterfly Valve Casting, Sealed Butterfly Valve
Casting, Cast Iron Butterfly Valve Body Casting
Product Description：
Soft sealing butterfly valve seal material is special, one side
is the metal material, and the other side is elastic
non-metallic materials. The butterfly valve sealing performance
is good, but it is not high temperature resistant, easy to wear
and poor mechanical. Hard seal butterfly valve is corrosion
resistance, high temperature and long service life, but it’s
poor sealing.
Sealing butterfly valve is a new kind of shut
off valve. Now, many manufacturers in china can process steadily
metal sealing butterfly valve, the production is widely used in
petroleum, chemical, gas and water supply and other industrial
piping.
In our foundry, the material of wafer
butterfly valve body mainly is cast gray iron or ductile iron,
also can be stainless steel or alloy class.
