Office media: fuel, foreign oil, diesel oil, aromatics, sulfur, etc. , air or other fuels chemical material, the selection of fire categories on the basis of 'HGJ21 - 89 '. According to China's 'code for fire protection fuel chemical preset ( GB50160 - 92). Regulation: 'a, b, fixed roof tank liquid shall be set flame arrestor and breather valve 'type, yoko enterprise research manufacturing SB series of new products, with specifications, compact structure, light weight, large air quantity closely, and the advantages of small leakage. Products are single breath valve, the suction valve, breathing valve, all kinds of structural type can be combined with the flame arrester construction, also can cooperate to manufacture the required to receive and manage. Q: breathing valve introduce a: respiration valve is fixed on top of the tank ventilation, to ensure normal tank pressure condition, avoid tank overpressure or vacuum tank is destroyed, also can detract from tank liquid volatilization losses. The operating pressure and temperature using background: exhale delay unloading a ship with the Industrial Valves power: B, 980 C and + 1750 pa pa + D, a + 4 kpa, E + 18 kpa suction pressure: B - 295Pa C、- 295Pa D、- 0. 5KPa　　( Operating pressure indicators can also be specified by the user) Using the background temperature: - 30 & 度; C - 60 & 度; C。 Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center. Three, it is very important when you use the occasion or the environment is more complex, would you please provide design drawings and detailed parameters, our engineers experts will concentrate on review and analysis for you. We can provide you with professional solutions, including design, customization, complete, operation and service. We've been working on the valve leader in the field of industry, to provide you with the latest knowledge of the valve, the best service, best technical adviser. Thank you for visiting our website, if you have any questions, you can call us, we will be dedicated to provide you with quality services. The factory provides professional ball Industrial Valves, butterfly valve, gate valve, globe valve, check valve, relief valve, safety valve, Marine valve, oil valve, hydraulic control valve and other kinds of valves.
os gate valve resilient seated gate valve, device for producing resilient seal gate valve, os&y valve, and other os&y gate valve, consisting of y gate valve.
As manufacturers we are determined to be the very best in wedge valve, regardless of the size, pedigree or inclinations of our competitors.
We are professional in manufacturing water gate valve, and always emphasize the technology and quality during the producing procedure.
The trend toward using cast iron gate valve flow control valve to ease os & y valve fire protection, once established, soon extended into such additional fields as cast iron valve and resilient seated valve.
