ASTM A217 Grade C12 valve

ASTM A217 Grade C12 valve

A valve which is primarily used for high temperature erosive refinery services is called as ASTM A217 grade c12 valves. It comprises higher chromium and molybdenum contents. It is also added up with phosphorous, manganese, carbon, silicon, making it the only material offering good strength and corrosion resisting properties. It also involves valves which have a diaphragm inside it and such valves are called as ASTM a217 gr c12 diaphragm valves. You would see the size range of this valves from 1/2 inch to 48 inch, with the range of pressure capacity between 150lb to 2500lb. These valves are very much demanded by industries which need high temperature and high pressure conditions to be fulfilled.

Before purchasing any A217 grade c12 ball valves, it is very important that you first verify it from your end whether this product is genuine or not. You can do this by following the below steps:

  • To meet the strength abilities of ASTM A217 uns j82090 ball valve, make sure it meets specification standards GB9112, DIN2501, BS4504, ISO2084 and ANSI125. These standards define the strength capabilities that this valve can withstand, along with the working pressure range between 1.6-6.4 Mpa.
  • Make sure that when you choose this ball valve, it must have the good tensile strength range lying between 620-795 Mpa.
  • Adding to this, it must also have a minimum yield strength value of 415 Mpa.
  • Considering the above two properties, strongly advisable that you also check the elongation and reduction of area which is 18% minimum and 35% minimum respectively.
