APPLICATION: For pressure reducing service where a supply of constant reduced pressure is required for pneumatic instruments and pilot operated controllers. FEATURES: Easily adjusted Internally relieving Available in Aluminum and 316 Stainless Steel CONNECTIONS: Inlet and Outlet - 1/4" NPT OPERATING TEMPERATURE: 0°F to 200°F (-18°C to 93°C) OPERATION: The diaphragm-operated design delivers constant downstreampressure by quickly responding to changes in volumerequirements. The DIAPHRAGM-SEAT ASSEMBLY moves freely up and down in response to slight changes in volume demand at the outlet port. As the DIAPHRAGM-SEAT ASSEMBLY moves the gap between the NOZZLE and NYLON SEAT changes, compensating for the change in volume demand. INLET PRESSURE: 4000 max. psig DESIGN PRESSURE: 5500 max. psig OUTPUT PRESSURE: 10 to 150 psig
