A unitary cup-shaped grid member having a grid of holes in the closed end is inserted in the inlet of a valve and a cup-shaped fine-mesh primary filter screen inserted therein and snap-locked in place. In the event the screen clogs and is removed by the user, the grid provides some back-up or auxiliary course filtering to protect the valve in service after removal of the primary filter screen.

Filtering flow in a valve

A valve assembly having a plurality of solenoid operated valving operators, each attached by non-metallic weldment to a manifold having a plurality of outlets. Two of the operators are adapted for connection to separate fluid sources such as hot and cold water and individually valved flow to a common mixing outlet on the manifold and also supply unvalved flow to an auxiliary passage in the manifold. Others of the valving operators are connected to receive flow from the auxiliary passage and provide valved flow individually to others of the outlets.

Modular valve assembly

A pilot operated electromagnetically actuated valve having a flexible diaphragm main valve operator with a rigid insert forming the pilot valve seat and passage. The pilot valving chamber cover serves as an armature pilot valve guide and also has plural spaced ribs engaging and guiding movement of the rigid insert and pilot valve seat. A separate inlet passage having an annular filter formed by circumferentially spaced grooves and a resilient flange provided on a disc member inserted in the valve inlet flow to a remote pilot bleed hole in the cover for supplying the pilot valving chamber.

Pilot operated electrically actuated value assembly

A pilot operated, diaphragm actuated fluid valve assembly having an annular main valve seat with a tapered annular surface disposed therearound. A movable diaphragm has a generally flat central main valving surface thereon and an integrally formed annular wiper extending outwardly therefrom. The annular wiper contacts the tapered annular surface a relatively small distance before the main valving surface contacts the main valve seat.
