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.

  

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.
