Bermad - Model X - Brass - 3 Way Universal Pilot

This multi-purpose, direct-acting, 3-Way positioning pilot is actuated by a pressure-responsive diaphragm, which tends to reach equilibrium with the set spring force. The pilot directs flow and pressure between its ports:

• When sensed pressure is above the set point, it connects port “C” to “0”
• When sensed pressure is equal to the set point, it blocks connections between all ports.
• When sensed pressure is the below-set point, it connects port “C” with “A” and “Z”. An integral needle valve restricts flow through port “Z”.
