Dual Valve Pressure Controller, Pressure Control Products by Alicat Scientific
...valve resulting in a total full scale accuracy of +/- 0.25% for most units. The modified loop and proportional control not only produces increases in precision control of the process pressure in closed or nearly closed systems, it also eliminates dead-band that is inherent in other pressure controllers that use pressure switches and on/off valves. See #2.
Anderson Greenwood / Crosby, Pilot Operated pressure Relief Valves
...be tight as high as 98 percent of set pressure. The main valve lifts proportionally, according to demand, restricting product loss to only that which must be relieved to prevent process pressure from exceeding the code allowance. The Series 400 is a no-flow, modulating action POPRV design suitable for gas, liquid and two-phase applications. The... See #3.
