CAST IRON VALVES

(also known as gray iron) is a type of metal that has been in use for hundreds of years. It is an alloy made from 96%-98% iron, 2%-4% carbon, and small amounts of silicone. It has impressive temperature tolerance, with some cast iron capable of handling temperatures over 2100F (1150C). When it comes to pressure, cast iron’s strength depends on its pressure class. The two most common are class 125 and class 250. At less extreme temperatures, class 125 cast iron flange is rated for pressures between 150 and 200 psi. Class 250 cast iron is a bit tougher, with pressure ratings from 300 to 500 psi. These pressures can vary by end type.

Cast iron is strong and will usually go undamaged even after going through intense vibrations. The main drawback of cast iron valves is that they are not very ductile at all. Virtually any bending will cause cast iron to crack and become useless. One great quality of cast iron is that it is not very expensive. As far as metals go, cast iron is usually the most economical option, which makes it a solid alternative for people on a budget.
