Slagging characteristics of a valve product structure, the use of slag valve flange bolt connection, both ends of the branch pipe connecting two flanged or butt, slagging valve opening and closing pieces using semi-hermetic seal deputy mandatory, excellent performance 3, slag valve sealing materials for wear-resistant alloys or ceramics, wear resistance PZ41H valve manufacturer, wear resistance, durable erosion, abrasion, friction is small, reliable sealing 4, slagging valve body outlet stream Road junction reasonable, does not exist slag, hoist flexible, non-jamming 5, slagging valve stem quenched and surface nitriding treatment, good to engage in resistance, scratch resistance and abrasion resistance 6, row Slag large caliber set rolling gate, open and close easily Disadvantages: easy to cause between the sealing surface erosion and abrasion, maintenance more difficult. Dimensions large open space requires a certain Shandong PZ41H slagging valve, opening and closing a long time. More complex structure. Parallel Gate Valve Gate Valve species, according to the sealing surface configuration can be divided into wedge gate-type valve and parallel gate-type valve, wedge gate-type valve can be divided into: a single gate type, double plate and flexible gate type; parallel gate type valve can be divided into single-gate type and double plate. Divided by the threaded stem position can be divided into two clear shot valve gate and dark bar. By shell / body material classification, valve can be divided into: metal materials valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium valves, Monel valves, copper alloy valves, lead alloy valves. Metal valve body lining: as rubber lined valves, lined valves, lead-lined valves, lined valves, lined valves enamel. Non-metallic materials valves: such as ceramic valves, glass valves, plastic valves. PZ41H slagging valve, valve manufacturers Everbright (certified), gate valve is provided by Shandong China Everbright Limited. Valve Co., Ltd. Shandong China Everbright (www.sdgdfm.com) Shandong Weifang, ball leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Everbright valve leadership with the staff warmly welcome all inquiries negotiations to create a better future for China Everbright valve.
