This multi-purpose, direct acting, 3-Way positioning pilot valve is actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force.
PRODUCT FEATURES & BENEFITS
The pilot directs flow and pressure between its ports:
■ When sensed pressure is above set point,
it connects port “C” to “0”.
■ When sensed pressure is equal to set point,
it blocks connections between all ports.
■ When sensed pressure is below set point,
it connects port “C” with “A” and “Z”.
An integral needle valve restricts flow through port “Z”.
