External corrosion valve pneumatic valve (including variable speed transmission box) inside and outside, at first, blasting sand blasting, non-toxic epoxy powder electrostatic spraying sought, thickness of 0.3mm or more. Large electrostatic spraying toxic epoxy resin valve difficulty should brush, spray similar to non-toxic epoxy paint. And various parts of the body inside the valve plate calls for a comprehensive anti-corrosion, on the one hand immersed in water will not rust gate, does not produce galvanic corrosion between the two metals; two aspects of smooth surface to reduce drag through the water. 6.3 valve body paint anti-corrosion epoxy resin or health requirements, should detect the appropriate authority of the agency report. Chemical and physical properties should meet the relevant requirements. In order to meet users to achieve operational automation Weifang valves, the company in addition to the supply of this series Weifang Z641F pneumatic valve, also available separately, including stents, including the cylinder block, helping users to the existing wide range of manual valve transformation, will twin pneumatic actuator part of the installation manual gate valve body large cover, can constitute a pneumatic cylinder - manual dual gate. Valve Co., Ltd. Shandong Everbright valve manufacturer specializing in the production, welcome new and old customers to order our products! Material category ① pneumatic valves pneumatic valve sealing surface varies, sealing methods and material requirements vary; ② ordinary wedge gate valves, Shandong, copper ring materials, fixation methods, polishing should explain; ③ soft sealing valve, the valve plate Physical chemistry and health testing data rubber lining materials; ④ valve sealing surface should be marked on the body sealing surface materials and butterfly board material; their physical and chemical test data, in particular the health requirements of rubber, anti-aging properties, wear resistance ; usually nitrile rubber and EPDM rubber, non-mixed with recycled plastic.
