Manifold pressure can be measured by using a 5/16”
I.D. hose in the right hand side of the valve and con-
necting a manometer. Two test gauge ports are acces-
sible for test gauge connection:
1. Tap on left side of the valve will give inlet supply
pressure.
2. Tap on the right side of the valve will give manifold
pressure.
