Product Operation Symbol
When de-energized, the 2-position 2-way proportional flow valve 20BL-08 acts as a check valve, allowing flow from ① to ②, and blocking flow from ② to ①. When energized, the ② to ① flow path is opened. Flow is proportional to the current applied to the coil. Flow varies with manual override.
