Abstract: A poppet valve (100) is provided according to the invention. The poppet valve (100) includes an actuator (120) including a pivoting armature (127) comprising a first end (105) and a second end (106). The pivoting armature (127) pivots at the first end (105). The poppet valve (100) further includes a tension connector member (129) connected to the pivoting armature (127) away from the first end (105) and a valve poppet (135) connected to the tension connector member (129). The pivoting armature (127) lifts the valve poppet (135) away from a valve orifice (110) via the tension connector member (129) when the actuator (120) is activated.
Abstract: The valve (100) comprises a valve body (101), a valve seat insert (103) assembled to the valve body (101), and a valve seal member (120) compressively assembled to and sealing to both the valve body (101) and the valve seat insert (103), with the valve seal member (120) including one or more port apertures (202).
Abstract: A valve unit (120) is provided according to the invention. The valve unit (120) includes a valve body (121), two or more fasteners (128) adapted for affixing the valve body (121) to a base, and two or more fastener grooves (125) formed in two or more sides of the valve body (121). The two or more corresponding fasteners (128) rest in the two or more fastener grooves (125). The valve unit (120) further includes a fastener link (100) extending between the two or more fasteners (128) and holding the two or more fasteners (128) substantially in the two or more grooves (125).
Abstract: An electrically actuated valve includes firstly a fixed core (1) accommodating, at least, one coil (2) in, at least, one housing and forming therewith, at least, one electromagnet of the electrically actuated valve. Further, this valve includes a body (4) forming with the fixed core (1) the sealingly tight carrier structure of the electrically actuated valve. Thirdly, this valve includes, at least, one movable core (3) placed between the fixed core (1) and the body (4). This electrically actuated valve is specially innovative in that the fixed core (1) is made as an unitary part from an injected ferromagnetic material and in that it combines several functions, in particular that of the pneumatic connection and/or of the electrical connection of the coil/coils (2). The decrease in the number of parts and the simplification of the design allow, accordingly, an additional miniaturization.
Abstract: A solenoid valve with protective cap (10) having electrical connection elements (11, 13) attached to the cap fits only the electromagnet (2) of a solenoid valve (1). A cavity (12) situated in the cap makes it possible to add on circuit band unit (20) providing circuits which complement the solenoid valve but vary from user to user. Cable connection elements, elements for visual indication of the functional state, delay circuits, interference-suppressing circuits, intrinsic safety circuits, circuits for detecting the position of the moving core, circuits for detecting the presence of fluid, logical indexing circuits etc. may be mentioned as examples of circuit elements which complement the solenoid valve. The solenoid valve also comprises connection elements (18) which permit a rational and cableless electrical link between at least two solenoid valves.
