A normally open solenoid operated modular valve includes a solenoid body receiving a coil and pole piece. A polymeric material valve body portion is releasably connected to the solenoid body. An armature/valve member slidably disposed in both the solenoid body and the valve body portion has a male threaded end shank. A polymeric material thread-in poppet/valve member includes an internal threaded portion engaging the male threaded end shank to retain the thread-in poppet/valve member on the armature/valve member. A resilient material valve ring is retained on the thread-in poppet/valve member. A cylindrical tube portion receives an armature/valve member rod portion. A biasing member acts against the armature/valve member and thereby acts to normally bias the valve ring away from contact with a valve seat surface created in the valve body portion defining a modular valve normally open position.
