The valve prevents flow from ① to ② until pressure at ① exceeds the set crack pressure
and opens the pilot section. The pilot flow creates a pressure differential across the
poppet which causes the valve to open allowing flow from ① to ② protecting the circuit
from over pressurization.
Pressure at ② is directly additive to the relief setting of the valve.
