WebThe differential pressure across the regula-tor is used as auxiliary energy to operate the valve. To open the regulator, this pressure must be at least as high as the min-imum differential pressure ∆p min specified in Table 1. The pilot valve determines the function of the regulator de-pending on how it is hooked up. Its output control pressure Webflow rates at various pressure drops. These conditions should be reviewed as an integral part of the control valve selection process. 6. DELTA P (∆P) SHUTOFF Unless otherwise specified by the user, ∆P shutoff is equal to the maximum inlet pressure with the valve in the fully closed position. 7. SEAT LEAKAGE
