Ceramic brake pneumatic valve of choose and buy of several major problems should be paid attention to

ceramic brake used pneumatic valve sealing surface components to replace common brake pneumatic valve surfacing welding carbide seal face. For ceramic brake pneumatic valve has the character such as wear resistance, corrosion resistance high temperature resistant, ceramic brake pneumatic valve is widely used in electric power, chemical industry, etc, is a major concern. However, many consumers in the choose and buy ceramic brake pneumatic valve is often not its method, and big nerve-racking, ceramic brake pneumatic valve should be how to choose and buy?
there are many different kinds of ceramic brake pneumatic valve, 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;
, selection of pneumatic valve materials. 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 ceramic brake pneumatic valve. Because the life of ceramic brake pneumatic 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 ceramic brake pneumatic valve is more convenient to use and can realize automation.
and see if factory made the pneumatic valve performance testing, pneumatic valves are through pressure test before delivery;
and see ceramic brake corrosion protection is in line with the requirements of the pneumatic valve;
and pneumatic valve manufacturers association, ceramic 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 colleagues should 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.
