Butterfly valve

Butterfly valve designs use a hard seat and an O-ring or piston ring around the disk to seal. Butterfly valve may include an angularly offset and disca pressure-tight resilient seat . Butterfly valvesrange in size from small to enormous, and are well suited for large flows of gases, liquids, or slurries, offer a number of advantages when used for the proper application. They may be used in a wide variety of chemical services, they are available with small dimensions allowing for use in areas where space is limited, and they allow a high coefficient of flow. Conversely, the design of butterfly valve creates the disadvantage of not being easy to clean, and therefore should be avoided in situations that call for sterile, medical or food processing applications. Additionally, some styles may have difficulty dispensing slurries.

1) Prevent the valve from being strongly striken in the process of installation and shipment, otherwise it may influence its normal performance.
2) Before installation, the user must check the valve flatly on the test clamps with some prepressing. It is not allowed to be freely-flip. This assures that magnetic material won’t be damaged by colliding, otherwise it will influence the magnetic force.
3) Clean the impurity such as aluminum or oil left on the inner wall of the stove and the surface of the valve.
4) Keep the good connection of the solenoid valve and thermocouple. Prevent the safety protection device from operating abnormally because of too big contact resistance.
5) The warehouse of solenoid valves must be dry and ventilated and strictly prohibit extrusion.
