The choose and buy plastic pneumatic valve remember these three points will be enough

pipeline transmission fluid must be used to pneumatic ball valve, to control the flow of the fluid. But in the fluid of all material, different material pneumatic ball valve with different performance, including plastic ball pneumatic valve because of their small size, light weight, easy to operation. The most commonly used in life and work. About buying plastic pneumatic valve ball, how to choose model, can satisfy their needs transmission, can maximum efficacy in the transmission. The following should be considered when selecting conditions?
first, fluid properties without fluid with different properties, some is corrosive, high pressure, there is a larger viscosity, etc. According to their own properties to select different type plastic ball pneumatic valve, can satisfy the needs of work. Such as corrosive liquid can't use common plastic ball pneumatic valve, it will directly led to the corrosion phenomenon, it appears that choose according to different properties, practical stronger, and more convenient for the users, use effect is better.
second, temperature measuring itself with some fluid temperature, have a plenty of high temperature, have a plenty of ultra-low temperature. Different temperatures for plastic ball pneumatic valve will affect performance, if choose wrong, then the property is easy to cause plastic balls pneumatic valve damage, reduce his life, and even lead to plastic balls pneumatic valve abnormal immediately, can't meet the work is in use.
third, under pressure to select different pipe size is different, they transfer fluid flow pressure. Plastic ball pneumatic valve, in particular, is to regulate pressure instruments, so that caused it to produce more stressful. If the pipe is big, plastic ball pneumatic valve also increases accordingly. If cannot bear fluid pressure, plastic ball pneumatic valve damage directly.
