Which is cheaper for pneumatic three-way butterfly valve? 3、 When the cryogenic liquid passes through the throttling element, with the change of pressure, vaporization and bubble extrusion may occur, which will cause great damage to the valve. For valves with this phenomenon, special consideration should be given to the structure of the valve and the material of the valve core internals. For flashing phenomenon, hard alloy (such as stelled) should be used as the valve core material. For cavitation phenomenon, the valve core should adopt a stepwise pressure reduction structure (such as cavitation cage structure) to eliminate cavitation.
、 At present, there are many different types of valve products, which have many different characteristics. For example, the electric butterfly valve is one of the good valve equipment. This equipment has many good quality characteristics. The use of this product is a combination of lever and ball, So that when people pull the lower lever during use, they can operate and control the sphere well, and then the whole sphere will block the whole pipeline to a certain extent. Therefore, this kind of equipment is a very good design, which can block the whole pipeline perfectly, To change the route or block the transmission media.
