Figure 1-1: Pilot in closed position

A. Needle valve / strainer

B. Manual pilot control

C. Inlet pressure

D. Outlet pressure

Fully open - No control

In

Figure 1-2

the valve is fully open. Y-port (P3) is open to Z-port (P2). The pressure on the

bottom of the piston (P1) is greater than the pressure at (P3) plus spring force. The valve
will not open unless the pressure drop across the valve (P1 minus P2) is slightly greater
than the force applied by the main valve spring. In a non-control state, the main valve is
opened in a percentage directly proportional to (P1 minus P2).
