10 Main Valve Applications Introduction
2016-12-10
1. Valve for Oil Plant
1.1 Oil refining plant: oil refining devices required valves are mostly pipeline valves, mainly like gate valve, globe valve, check valve, safety valve, ball valve, butterfly valve, steam trap, in which gate valve accounts for about 80% of the total valves (Valves cost account for 3% to 5% of the total investment).
1.2 Chemical fiber plant: main chemical fiber products are three categories polyester, acrylic, vinylon. It needs to use ball valve, jacketed valve (jacket ball valve, jacket valve, jacket globe valve).
1.3 Acrylonitrile plant: the device is generally required gate valve, globe valve, check valve, ball valve, steam trap, needle valve, plug valve, gate valve which accounts for about 75%.
1.4 Ammonia synthesis plant: as the ammonia synthesis and the purification method are different, its technological process also different, the technical performance of the required different as well. At present, general ammonia plants mainly need gate valve, check valve, check valve, steam trap, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, high temperature low temperature valve.
2. Valve for Hydropower Station
The world’s power plant construction is developing in the direction of large-scale, so the required valves with features of large diameter and high pressure, such as safety valve, relief valve, globe valve, gate valve, butterfly valve, emergency valve and flow control valve, spherical sealing instrument glove valve.
3. Valve for Metallurgical Industry
Among metallurgical industries, aluminium-oxide fields need wear-resistant slurry valve, regulating steam trap. Steel industry need metal seated ball valve, butterfly valve and oxidation ball valve, globe valve and four-way valve.
4. Valve for Marine Industry
With the development of offshore oil field development, the valve consumption for marine-fields valves are gradually increasing as well. Offshore platform required to ball valve, check valve, multi-way valve.
5. Food and Pharmaceutical Required Valve
The industry need to use stainless steel ball valve, non-toxic full-plastic ball valve and butterfly valve.
6. Valve for Rural & Urban Infrastructure Construction
Construction generally requires low-pressure valve, the current development directions are going for environmental protection and energy-saving. Environment-friendly plastic plate valve, balance valve and concentric butterfly valve, metal seal butterfly valves are gradually replacing the low-pressure iron gate valve. Urban buildings need to use the valves like the balance valve, resilient seat gate valve and butterfly valve.
7. Valve for Heating System
In modern heating system, need a large number of metal seated butterfly valve, horizontal balance valve and buried type ball valve, because these types of valves can solve the vertical and horizontal hydraulic imbalance problem, reaching the purpose of energy conservation, generation Heat balance.
8. Valves for Environmental-Protection Purpose
In current environmental protection system, the main water supply system need to use concentric butterfly valve, resilient seat gate valve, ball valve, exhaust valve (for the removal of air in the pipeline). Sewage treatment system mainly needs resilient seat gate valve and butterfly valve.
9. Valve for Urban Gas
City gas valves accounts for 22% of the entire natural gas market with big valve consumption and many kinds of valve, The main required types are ball valves, plug valves, pressure relief valves, safety valves.
10. Valve for Pipeline Construction
Long-distance pipeline is mainly used for transporting crude oil, finished oil products and natural gas. The pipeline requires most are forged steel three piece full-bore ball valve, anti-sulfur slab gate valve, safety valve, check valve.
