WebSep 28, 2007 · Here's what I believe the sizing procedure looks like: 1. Look at pump curve to find head at minimal flow for pump (maybe 5-10% safety factor on flow). 2. Calculate pressure drop through bypass line without orifice (will of course be lower than head on pump curve at minimal flow). 3. Webdischarge pressure below the setting, the pilot valve will be closed; at any pressure higher than the setting, the pilot valve will be open. Water enters the pilot valve at pump discharge pres-sure. An orifice permits water to flow to a line leading to the relief valve. This line also is connected to pump
