Inches water column (in WC)

Inches of water column is a unit of pressure mainly used in North America to measure small differences in pressure. 1 inch of water is the pressure exerted by a 1 inch high column of water at a given temperature. It can also be represented as in WC, inAq, inches water gauge, or in H2O. Air and other industrial gasses are often measured in inches of water when at low pressure rather than inches of mercury or pounds per square inch (psi).

The direct sealing diaphragm technology of Equilibar back pressure regulators offers unmatched precision for challenging pressure control situations including those in aerospace, research, catalysis, two-phase flow, cryogenic, biotech, and extreme temperatures.

Valve Magazine features Alan Black’s overview of plastic valves

The summer issue of Valve Magazine features a comprehensive overview of plastic valves by Alan Black, Equilibar’s lead application engineer and product manager. During the 1950s and 1960s, plastics represented a future filled with progress and possibility, as was famously captured in Dustin Hoffman’s first movie, The Graduate. “I have one word for you,” a Read More
