Pneumatic valve models have to consider five points

it is well known, is a kind of pneumatic valve used in gas liquid transmission and control of a tool, at present in the fluid piping system is very widely used. Flat brake pneumatic valve manufacturer believes that the main purpose of the pneumatic valve is the isolation equipment and piping system, regulating flow, preventing backflow, and discharge pressure, etc. , to ensure that the important role of the play, pneumatic valve selection is very important. Here, let's talk about pneumatic valve selection problem, hope to be of help.
. As we know, conventional pneumatic valves have a butterfly pneumatic pneumatic valve, ball valve, gate valve and plug pneumatic valve and a few species, therefore, should be fully considered in the process of pneumatic valve selection range of pneumatic valves used in water supply network.
. Pneumatic ball valves and cocks pneumatic valve casting and machining difficulty is big, the price is more expensive, usually applies to some small diameter pipeline. And pneumatic ball valve in the process of use, can maintain brake pneumatic valve small flow resistance, reliable seal, flexible movement, convenient operation and maintenance and so on a series of advantages. Cock in the process of the pneumatic valve in use, of course, also has the advantages of similar just water cross section is not round.
. Turns the soil depth, in order to reduce the pipe plate brake pneumatic valve manufacturer told us that the general diameter larger pipe will be equipped with some fine adjustment of pneumatic valve to use, can play a good effect. Adjustment, however, the use of pneumatic valve is also has some disadvantages, the most main is butterfly plate to occupy a certain section water, can increase the water head loss.
. If turns the soil depth requirement is not high, flat brake pneumatic valve manufacturer recommendations, pneumatic valve or gate effect is better. But the height of the pneumatic valve gate is also affect turns the soil depth of pipeline, and the length of the large diameter horizontal pneumatic valve gate is enlarged pipe transverse area, thus affecting other pipeline arrangement, these are all pay attention to.
. In recent years, due to the constant improvement of the foundry technology, pneumatic valve plate gate manufacturer told us a new method of resin sand casting, which can effectively reduce the mechanical processing, thus greatly reduce the production cost. So, from this level, pneumatic ball valve used in large diameter pipeline or worthy of our exploration on the feasibility, as for the clear dividing line between diameter size also should be taken into account according to the specific situation.
the place on put together is narrated, pneumatic valve selection is to consider a few questions. The flat brake pneumatic valve manufacturer that, in the face of a wide range of pneumatic valves, choose the most suitable pneumatic valve is very not easy, in the process of selection must will give full consideration to these problems.
