The choose and buy brake pneumatic valve need to pay attention to what issues?

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 how to choose and buy? 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:
universal standard, the ceramic brake pneumatic valve, pneumatic valve, such as ceramic brake specifications category, mainly has pneumatic valve nominal diameter, nominal pressure and temperature requirements that several parameters.
pneumatic valve pneumatic valves, ceramic brake material choice. 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.
pneumatic valve, ceramic gate 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 whether manufacturer do the ceramic brake pneumatic valve performance testing, ceramic brake pneumatic valve 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 negotiate ceramic gate way of packing and shipping, ceramic brake when transported pneumatic valve should be set up on both sides of lightweight wall panel enclosed, a 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 ceramic brake pneumatic valve can in straw rope bale, and transportation by container;
and carefully read ceramic brake pneumatic valve product manuals and their requirements are consistent.
