Pneumatic valve stainless steel gate of several major problems that should pay attention to the choose and buy

stainless steel brake used pneumatic valve pneumatic valve sealing surface components to replace ordinary gate of stainless steel welding carbide seal face. For stainless steel brake pneumatic valve wear resistance, corrosion resistance high temperature resistance and other characteristics, stainless steel brake pneumatic valve is widely used in electric power, chemical industry and other fields, in focus. However, many consumers in the choose and buy method of pneumatic valve is often not its stainless steel gate, and big nerve-racking, stainless steel brake pneumatic valve how to choose and buy?
there are many different kinds of pneumatic valve, stainless steel gate when the choose and buy should combine their own conditions and transmission fluid medium, the specific matters needing attention are as follows:
and see the general standard of pneumatic valve, such as pneumatic valve specifications categories, there are mainly pneumatic valve nominal diameter, nominal pressure and temperature requirements that several parameters;
pneumatic valve, stainless steel gate valve material selection. According to working condition of selecting suitable materials, such as cast iron, cast steel, carbon steel, stainless steel, ceramics, etc. If the budget is limited, can choose cast iron pneumatic valves, if the budget is enough, suggested that choose pneumatic valve stainless steel gate. Because the life of pneumatic stainless steel gate valve can achieve common metal pneumatic valve times, high cost performance.
and pneumatic valve operating mechanism; Mainly include manual, electric, pneumatic, hydraulic, electric hydraulic, etc. , this also want to choose according to your specific needs and budget. Manually if the price is lower, electric pneumatic valve stainless steel gate is more convenient to use, can realize automation.
and see if factory made the pneumatic valve performance testing, pneumatic valves are through pressure test before delivery;
, the stainless steel corrosion protection is in line with the requirements of the pneumatic valve gate;
pneumatic valve, and manufacturers of stainless steel gate way of packing and shipping, should be set on both sides of pneumatic valve to transport light wall plate enclosed, large diameter pneumatic valve at the same time to have simple retainer packaging wood frame, in order to avoid clash in the process of transportation, medium and small pneumatic valve can be in straw rope bale, and transportation by container;
read product manual carefully to see, and for your requirements.
