Mateial Selection Guidance
Data Sheets Manual
The below chart is intended to provide the end user and valve selection staff with a useful guide to material compatibility.
No contractual responsibility is accepted by our company as result of wrong use of this list of compounds and materials.
It has to be born in mind that the process may change behavior depending on other parameters such as pressure,
temperature, concentration, fl uid velocity…etc. The Valve materials are wide in their specification, i.e: Iron foundry refers
to Cast Iron A126 or other grades, Ductile Iron and other Iron alloys. Carbon Steel applies to A216 WCB however other
cast steel alloys such as LCB, WCC have to be interpolated between this cast steel and the superior Stainless Steel. Other
materials and elastomeric compounds not covered in this table can be advised by our technical team.
