Payment Terms:	L/C, T/T
Supply Ability:	According to requirment
Place of Origin:	Shanghai

This kind of valve has a circular disk as its closing element. The standard design has the valve stem running through the disk, giving a symmetrical appearance. Later designs off-set the stem, so that the disk "cams" into the valve seat. Advantages include less wear and tear on the disk and seats, and tighter shut-off capacities. Many design types are available including inexpensive? Teflon or resilient seats for use in water(treatment) plants, etc. More expensive metal seats can be used where high temperatures or aggressive chemicals are encountered. So-called "High Temperature" butterfly valves offer zero leakage designs and have been applied in both the chemicals and hydrocarbon processing sectors.
