WebIf the regulator is used in conjunction with a 289H relief valve, the Type 289H should be set 10" W.C. higher than the outlet pressure setting of the regulator, up to 30 inches W.C. reduced pressure. For pressure greater than this, set the 289H 3/4 psi higher than the outlet pressure setting of the regulator. WebHigh flow rates - As shown by the Figure 3 capacity curves, high flow rates can be achieved with minimum pressure buildup due to the boosting system which increases the relief valve opening. Small size - The 289 series relief valves are small and compact, making them suitable for areas limited in space. Reliability due to simplicity - A single ...
