Pneumatic valve production after the test

in the performance of the pneumatic valve production after the need for detection, can in the later testing on a large scale manufacturer to a large number of capital investment of equipment, mainly in terms of several performance testing, the following by the small make up to make a simple introduction on performance test on the above several points. The place where it is necessary to detect the pneumatic valve is in normal working pressure, opening and closing the torque for the open-close torque is a rule. And in the normal operating pressure of the situation, also need to ensure that the valve in the closed tightly when need continuous opening and closing how much is the number of times, the number of times to ensure that within the indicators, if more than this range will need to adjust, its specification parameter values. At the same time, the pneumatic valve in the pipeline system for use when need to pay attention to the medium inside pipeline produced under the condition of the flow resistance coefficient is how much, because of the existence of this standard is can produce serious threat to pneumatic valve sealing performance.
