Product Operation Symbol
When de-energized, the 22DH-A08-J acts as a check valve, allowing flow from ① to ②, while blocking flow from ② to ①. When energized, the cartridge's poppet lifts to open the ② to ① flow path. In this mode, flow from ① to ② is severely restricted.
Operation of Manual Override Option
To manually override, pull and hold the knurled knob. This override is not detented. The pull force required is approximately 24 lbs. The"J" option includes a male 10-32 thread for a cable attachment. If a cable is used, the internal valve spring may not provide enough force to overcome internal cable friction. An external means of returning the cable must be provided by the user.
