The simplest of pressure reducing valves, the direct-acting OB-2 and OB-2G operate with either a flat diaphragm or convoluted bellows. Since it is self-contained, it does not need an external sensing line downstream to operate. Small and economical, the OB-2 and OB-2G are designed for low to moderate flows. Accuracy of direct-acting PRVs is typically +/- 10% of the downstream set point.
