Abstract: A valve apparatus that includes a valve assembly including valve body that defines an inlet, a first outlet, and a second outlet, and including a poppet located in the valve body that includes a valve member. An actuator assembly is attached to the valve assembly that includes an armature that is coupled to the poppet and is configured to move the poppet and the valve member to control a flow of fluid through the valve assembly from the inlet to either the first outlet or the second outlet. A diaphragm is located between valve assembly and the actuator assembly that is configured to seal the valve assembly from the actuator assembly.

Abstract: A valve including a valve assembly and a solenoid assembly. The solenoid assembly is coupled to the valve assembly to actuate the valve assembly. The solenoid assembly includes a movable armature engaged with a poppet of the valve assembly. A plate spring having a spring force is positioned between the valve assembly and the solenoid assembly that is configured to bias the valve member of the poppet into engagement with a valve seat. Based on the spring force of the plate spring and the voltage or current that is applied to the solenoid coil, the solenoid assembly is configured to control a distance that the valve member moves relative to the valve seat to proportionally control an amount of flow that is permitted through the valve assembly.

Abstract: A solenoid pump that includes a base and a solenoid having a coil and a pole piece. A retainer body, positioned inside the solenoid and the base, includes an armature cavity that receives an armature in a sliding fit for movement between energized and de-energized positions. A diaphragm, mounted in the armature cavity, is connected to the armature. An inlet check valve permits fluid flow in only a first direction moving from an inlet port toward the diaphragm. An outlet check valve permits fluid flow in only a second direction moving from the diaphragm toward an outlet port. A fluid flow path extends through the retainer body from the inlet check valve to the diaphragm and from the diaphragm to the outlet check valve for transporting fluid from the inlet check valve to the outlet check valve as the diaphragm oscillates between first and second positions.

Abstract: A pneumatic control valve manifold assembly including a modular manifold segment with first and second valve receiving bores, inlet and exhaust cavities, and fluid passageways. The modular manifold segment has a mating face and a back-side face.
