Design and principle of operationThe pressure reducer comprises a globe valveAnd an actuator with attached pilot valve. The pressure reducer is designed for maintain-ing the pressure downstream of the valve at aSet point value adjusted on the pilot valve. The valve closes when the downstream press-ure rises. The medium flows through the valve as indi-cated by the arrow. The position of the valvePlug and hence the free area between thePlug (3) and seat (2) controls the down-stream pressure p2. The forces acting on the valve plug are bal-anced upstream and downstream by a bal-ancing bellows (5). The upstream pressure p1 is supplied asAuxiliary energy to the pilot valve via con-trol line, causing the pilot valve to produceA control pressure PS as a function of the setPoint adjustment. In controlling, the forces which are PRO-duced on both sides of the operating dia-phragm (6) are compared. Here, the forceOf the control pressure PS acts on one sideOf the diaphragm via the control line (12), And the force of the downstream pressureP2 together with the force of the positioningSprings (7) acts on the other side. If, e. G., the downstream pressure p 2 to be con-trolled decreases, the control pressure pSRisesAnd the valve opens correspondingly. If the downstream pressure p2 equals theControl pressure p S, the valve is closed byThe force of the positioning springs (7). Important: For the valve to function proper-ly, the minimum differential pressure p min Must be in accordance with the values listedIn the table.
