A valve flow-directing vessel () comprising a sleeve () having a threaded installation portion () for connection to a receiving member, a plunger () movable within the sleeve () between a closed position and an opened position, and an orifice insert () fixedly attached to the sleeve (). The orifice insert () defines an orifice () that is sealed when the plunger () is in the closed position and unsealed when the plunger () is in the opened position. The orifice () is the entrance to a passageway () having an exit () communicating with a delivery passage of the receiving member, and this exit () is positioned beyond the threaded installation portion () of the sleeve ().

Solenoid valve

A solenoid assembly for a valve includes a unitary, one-piece housing comprised of encapsulant. An electromagnetic device is completely encompassed by and embedded in the encapsulant. The device includes i) a bobbin and coil subassembly; ii) a terminal electrically connected to the coil; iii) a yoke surrounding the subassembly; iv) a flux plate electrically connected to the yoke and insulated from the coil such that a flux gap is provided between the coil and yoke; and v) a flux bushing closely received in the bobbin. Lead wires are electrically connected to the terminal and have one end embedded in the encapsulant. A hollow conduit receives and encloses the lead wires, and also has one end embedded in the encapsulant. Upon energization of the coil by current applied to the lead wires, electromagnetic forces generate a magnetic field which can be transmitted to a valve member received in the solenoid assembly.

One-piece coil conduit

In a pilot-operated valve having a valve body, including inlet and outlet portions controllably interconnected via a main piston bore portion; a main piston movable within the main piston bore; an operator portion; an operator assembly including a movable plunger assembly; and an actuating mechanism for actuating the plunger assembly, wherein the improvement comprises a further bore located within the valve body and a manually-operated override assembly retained therein, including a stem having a tool actuating portion; a cam portion extending radially into the operator bore portion and, upon a first predetermined rotation physically actuating the plunger assembly; and an actuating surface extending tangentially into the main piston bore portion which, upon a second rotation physically actuates the main piston. A method of actuating the manual override assembly is also set forth.
