The ¿P Valve is the only one to be equipped with gage ports. The pressure differential in psi, also know as ¿P (Delta P), is obtained by taking the readings of the gauge on each side of the pump. The pump curves demonstrate the ¿P in head loss. In order to convert the readings of the gage in head loss, multiply the ¿P by 2.3.
