Small deviations in pressure drop can have big impacts.

When determining availble pressure for selecting valves, don’t forget to account for strainers, filters, piping length, elbows, vertical runs, and the presence of or***ce plates. Overlooking these factors can significantly reduce available supply pressure—leading to uneven heating or cooling and wasted energy. 📉

Metrex Valve provides charts, tools, and expert guidance to help engineers make precise, real-world selections.
