How to choose Norgren filter pressure reducing valve in pneumatic components

How to choose the Norgren filter pressure reducing valve in pneumatic components?
Now the filter and pressure reducing valve can be integrated into a filter pressure reducing valve, and the structure is also optimized. The use of the filter pressure reducing valve not only reduces the installation space, but also reduces the cost, but the disadvantage is that the flow rate of the general filter pressure reducing valve is not as large as the flow rate of the pressure reducing valve in the triple piece, and the same flow effect is required. The design of the internal compartment of the filter pressure reducing valve is an important part. The selection of a suitable two-piece filter pressure reducing valve is not only the above advantages, but also the same in the latter section.
Filter the pressure reducing valve. Because it is a replacement filter and a pressure reducing valve, the following points should be noted in the selection of the filter pressure reducing valve:
1. Filter effect
It is necessary to pay attention to the internal filter design of the filter, whether it can remove water and impurities, not only to replace the filter filter, which leads to an increase in the cost of consumables, and not because the filter is poor, which causes the water to run behind. The rear air source equipment is easily damaged.
2. Voltage regulation effect
Like the pressure reducing valve, the atmospheric pressure should be adjusted according to the set output pressure, and the pressure change should be quickly reacted. The internal cabin design of the pressure reducing valve is very important, not only the material of the diaphragm of the pressure reducing valve is important, but also affects the flow rate. And the change in pressure difference. Generally, everyone will ignore this part and choose a larger diameter than the pressure reducing valve. For example, if the original pressure reducing valve is 2 points, the filter pressure reducing valve will be 3 points to avoid insufficient flow.
In fact, the appropriate filter pressure reducing valve is not only the choice of low price, because there are too many imitations, one considers the price, but ignores the importance of the product itself. Appropriate filter pressure reducing valve, in addition to considering the filtration effect, the material and design of the filter cup are not easy to be broken, and the filter pressure regulator effect and the flow output of the filter pressure reducing valve are taken into account, and the filter and the decompression can be completely replaced. Valves, without having to increase the size to increase costs.
