Needle valve X

for controlpressure-reducingfor water

This pilot integrates all principal functions of a 2-Way control circuit in a single assembly. It is a direct acting pilots valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. When used in a pressure reducing circuit, the pilot modulates closed as downstream pressure rises above set point. An integral needle valve acts as an upstream flow restrictor as well as a closing speed control. 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”.
