A control valve having a valve body, seat member, valve member, and solenoid including a housing, bobbin, and coil. The valve member has a head portion disposed within the bobbin and a valve portion, disposed within the valve body, that has a seat engagement member operating to open and close ports in the valve body when the valve member slides between first and second positions. A permanent magnet, disposed within the bobbin, applies an attractive force of variable magnitude to the valve member in a direction opposing a biasing force created by a biasing component. Pulses of electric current applied to the coil change the variable magnitude. The permanent magnet pulls the valve member to the second position when the attractive force is greater than the biasing force and the valve member returns to the first position when the attractive force is less than the biasing force.

Latching pneumatic control valve

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. The fluid passageways are arranged in fluid communication with the first and second valve receiving bores, are open to the modular manifold segment mating face, and have multiple configurations. The modular manifold segment mating face includes an abutment surface surrounding the fluid passageways that has a plurality of shapes depending upon the configuration of the fluid passageways. The modular manifold segment back-side face includes a plurality of sealing ribs arranged in a pattern that universally mates with each of the different shapes of the abutment surface such that multiple modular manifold segments with different fluid passageways can be stacked next to each other.

A multi-port valve having a longitudinal axis and a solenoid coil wound about a bobbin. Coaxially aligned with the longitudinal axis is an armature, at least partially disposed within the bobbin. The armature is coupled to a valve member that forms a sealing relationship with at least one valve orifice. A two-piece can having a first can component and a second component that cooperate to define an interior region. The solenoid coil, bobbin, pole piece, and at least part of the armature are disposed in the interior region of the two-piece can. The second can component is adjustably threaded to the first can component such that a longitudinal dimension of the interior region of the two-piece can may be adjusted to vary the size of a gap between the pole piece and the armature.

A solenoid operated modular valve includes a solenoid body having a coil and a pole piece positioned in the solenoid body. A valve body cartridge is connected to the solenoid body. A polymeric snap-in seat assembly includes first and second deflectable claw arms each having a barb engaging the valve body cartridge retaining the snap-in seat assembly in direct contact with the valve body cartridge. A seat engagement face when contacted by a valve seal member defines a valve closed position, and is displaced away from the seat engagement face in a valve open position when the coil is energized. A valve body cartridge body end portion includes a barb engagement face having pitched contact edges each having a continuous pitch directly contacted by the barb of the first and second deflectable claw arms to rotatably and frictionally lock the snap-in seat assembly to the valve body cartridge.

A normally open solenoid operated modular valve includes a solenoid body receiving a coil and pole piece. A polymeric material valve body portion is releasably connected to the solenoid body. An armature/valve member slidably disposed in both the solenoid body and the valve body portion has a male threaded end shank. A polymeric material thread-in poppet/valve member includes an internal threaded portion engaging the male threaded end shank to retain the thread-in poppet/valve member on the armature/valve member. A resilient material valve ring is retained on the thread-in poppet/valve member. A cylindrical tube portion receives an armature/valve member rod portion. A biasing member acts against the armature/valve member and thereby acts to normally bias the valve ring away from contact with a valve seat surface created in the valve body portion defining a modular valve normally open position.

Disclosed is a sanitary acoustic horn for use in the dairy industry for preventing powder build-up in dairy industry drying systems and for meeting U.S.D.A. requirements for equipment which comes in contact with powder product. The sanitary acoustic horn includes a driver and a bell connected to one another by means of sanitary ferrules and quick connect hinged clamps. The sanitary acoustic horn is preferably made from 304 stainless steel and having at least a number 4 finish on all surfaces which will be exposed to powder product. A number 4 finish inhibits the collection of powder on such surfaces by eliminating pits, scratches, grooves and the like therefrom. The quick connect clamp allows for easy assembly and disassembly of the horn for a manual cleaning. The sanitary horn further includes an air delivery chamber which extends about the driver. Such air delivery chamber has sufficient dimension to allow insertion of human fingers and cloths so that such surfaces may be easily cleaned. Further, all corners of the equipment which will come in contact with powder product are ground and polished to a minimum 1/4' radius or, at least, to a minimum radius equal to the thickness of the material.

Sanitary acoustic horn

Disclosed is an acoustic horn to aid in bulk powdered material handling particularly from trucks and railroad cars. Such acoustic horn is comprised of an external cone having a driver affix thereto. There is also an inverted internal cone contained within the external cone. There is a cylindrical throat communicating with the acoustic wave driver which extends into the internal cone, the combination of the throat extending into the internal cone contained within the external cone creates a folded horn arrangement wherein a horn of relative shortened length can achieve the desired low fundamental frequencies needed for bulk powdered material handling. Extending radially from the mouth of the external cone is a flange. Means are provided to detachably affix said flange from the flange on existing manways present on trucks and railroad cars.
