Attention:
1.The valve is installed independent of the flow direction of the medium.
2.After the valve is assembled, the thread of the bolt/stem shall be greased to prevent corrosion and facilitate subsequent disassembly.
3.Do not use the valve for pipe pressure regulation, gate valves generally play the role of a switch, to achieve a good adjustment effect, it is recommended to choose a professional regulating valve, water erosion will affect the service life of the valve disc.
4.Do not use valves with EDPM for gaseous fluids.
Definition and use Cast steel flange hard sealed butterfly valve is a valve widely used in industrial pipelines, with various advantages and applicability. The main features of cast steel flange hard seal butterfly valve include: Material diversity: The valve body material is mainly cast steel, but also includes carbon steel, 20 # steel, A182 steel, forged steel A105 F11 F22, chromium molybdenum steel WC6 WC9, stainless steel 304, 316, etc., to adapt to different working environments and medium requirements. Wide range of specifications: Valve specifications range from DN15 to DN1200, with a pressure range of 1.0-50Mpa, suitable for various sizes of pipeline systems. There are various driving modes available, including manual, electric, pneumatic, and gear transmission devices, to meet different operational needs. Excellent sealing performance: Designed using the three-dimensional eccentric principle, the spatial motion trajectory of the sealing surface is optimized, with no friction or interference between the sealing surfaces. In addition, the appropriate selection of sealing materials improves the sealing, corrosion resistance, high temperature resistance, and wear resistance of the butterfly valve. Widely used: It is not only widely used in industries such as petroleum, chemical, power, metallurgy, food, medicine, textiles, and papermaking, but can also be installed on industrial pipelines with temperatures ≤ 425 ºC for regulating flow and cutting off media. The structure of cast steel flange hard sealed butterfly valve includes main components such as valve body, butterfly plate, multi-level valve seat, valve stem, and transmission mechanism. Its structural principle design is unique, using the three-dimensional weaving principle to make the butterfly plate tighter and tighter when closed, achieving a leak free effect. In addition, the valve has good fluid control characteristics, small opening torque, flexible and convenient, labor-saving and energy-saving. Cast steel flange hard sealed butterfly valve has become an indispensable and important component in industrial pipeline systems due to its excellent performance and wide application fields.
Aluminum Die Casting is a method for creating aluminum parts that are well textured or smooth, and have a good surface finishing, and high dimensional stability. The reasons why aluminum is used for metal casting are as follows:
1.It is lightweight and very stable for complex shapes and thin walls.
2.It has high thermal and electrical conductivity.
3.It has good corrosion resistance.
4.It retains its strength at very high temperatures. Advantages Of Aluminum Die Casting Parts
5.Aluminum being a lightweight alloy allows making lightweight parts without compromising their strength.
6.It has the versatility to produce thin-walled simple or complex-shaped parts with good precision.
7.Aluminum cast parts are well textured or smooth depending on the requirements.
8.Since the process is very fast, it allows producing tens of thousands of parts in less time and cost.
9.This mass production is very cost-effective in contrast to other die casting processes.
10.The parts are highly corrosion resistant and are excellent conductors of heat and electricity.
