Features of ISP08-20 2-Way N.C. Poppet Valve
Operation Symbol of ISP08-20 2-Way N.C. Poppet Valve
When de-energized, the ISP08-20 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.
