Model S1 - Pressure Reducing Valve with bellows The medium flows through the valve body in the direction indicated by the arrow. The position of the valve plug determines the flow rate across the area released between the plug and seat. To control the pressure, the operating diaphragm is pretensioned by the positioning springs and the set point adjuster. As a result, the valve is opened by the force of the positioning springs in pressureless state (p1 = p2). The downstream pressure p2 to be controlled is tapped downstream of the valve and transmitted through the control line to the...
