Abstract: A manifold mounting system for electrically operated pneumatic control valves includes a push-on snap lock latching arrangement that is responsive to simple straight line connecting movement of the valve to the manifold. The system completely eliminates the need for end plates, screws, O-rings, gaskets and the like, and the simultaneous accommodation of a plug-in electrical connection also eliminates wiring connections. Manual push button release provides equally simple disconnection of the valve from the manifold.

Abstract: An improved valve construction having increased flow/pressure characteristics. The valve comprises a molded valve body including a plurality of body sections each having a generally flat inner surface, and the inner surfaces are disposed in contiguous relation along an interface. Each inner surface is formed with a plurality of recesses that mate with and complement recesses in the inner surface of the other body section to form a valve chamber and a connecting piston chamber. A spool valve is mounted for sliding movement in the valve chamber, while a piston having a generally oval cross-section is connected to the spool and is mounted for movement in the oval-shaped piston chamber. The inner surfaces of the body sections are also formed with a plurality of channel portions which mate and complement channel portions in the other body section to form flow channels that communicate with the valve chamber and the piston chamber.

Abstract: A valve stack assembly comprising a manifold having an inlet channel connected to a source of air. A plurality of inlet tubes each having an inner end communicating with said inlet channel and the outer end of each tube projects outwardly of the manifold and is sealed within an inlet passage of a valve. An annular collet is disposed in each inlet passage and receives the inlet tube and the collet is designed such that the tube can be freely inserted in the collet but cannot be freely withdrawn unless the collet is moved axially inward to a release position. Each valve also includes an outlet opening which receives an outlet tube mounted in the manifold and each outlet tube is connected to a transverse manifold passage which in turn is connected through a fluid line to a working element.

Abstract: A valve construction comprising a molded body including a plurality of body sections each having a generally flat inner surface. The flat surfaces of the body sections are disposed in contiguous relation along an interface. Each surface has a plurality of recesses that mate with complementary recesses in the surface of the other body section to form compartments in the assembled body, and operating components, such as valves, are located in the compartments. The movable elements of the operating components move in a direction parallel to the plane of the interface. Each surface also has a plurality of channel portions mating with complementary channel portions in the other surface to form channels that interconnect the compartments. Each surface also includes a plurality of port sections which mate with port sections in the other surface to form ports which establish communication between the channels and the exterior of the body.
