Type 36-3 Safety Shut-off Valve (SSV) with Pressure Reducing Valve - 2

Principle of operation The medium flows through the valve in the direction indicated by the arrow. The position of the plug determines the flow rate across the area released between plug (3) and seat (2). The pressure to be controlled is transmitted to the diaphragm (9) over a control line (12) and converted into a positioning force. This force moves the plug stem (4) and the valve plug (3) with it, opposing the force of the set point springs (7). The spring force (pressure set point) can be adjusted at the set point adjuster (6). The regulators are equipped with two independent operating...
