QB3H Electronic Pressure Control to 500psig


The QB3H is an electronic pressure control valve with integral volume booster for high flow rates at high pressures up to 500psig. Designed for the laser cutting assist gas market, the QB3H is available in a nickel plate brass body version that is cleaned for oxygen. A lightweight aluminum body is available for inert gas applications. The QB3H uses an internal stainless steel pressure transducer to close the loop around the output pressure. This allows the 0-10VDC or 4-20mA analog command reference signal to be converted to a linear and accurate output pressure.
