POSITIONING PILOT VALVE WW- PBLX

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 set point, it connects port “0” to “3”. ֺ When sensed pressure is equal to set point, it blocks connections between all ports. ֺ When sensed pressure is below set point, it connects port “3” with “2”
