A valve including a valve assembly and a solenoid assembly. The solenoid assembly is coupled to the valve assembly to actuate the valve assembly. The solenoid assembly includes a movable armature engaged with a poppet of the valve assembly. A plate spring having a spring force is positioned between the valve assembly and the solenoid assembly that is configured to bias the valve member of the poppet into engagement with a valve seat. Based on the spring force of the plate spring and the voltage or current that is applied to the solenoid coil, the solenoid assembly is configured to control a distance that the valve member moves relative to the valve seat to proportionally control an amount of flow that is permitted through the valve assembly.

Proportional solenoid valve

A pulse valve assembly including a main valve and a pilot valve that selectively actuates the main valve.

Pulse valve

A solenoid pump that includes a base and a solenoid having a coil and a pole piece. A retainer body, positioned inside the solenoid and the base, includes an armature cavity that receives an armature in a sliding fit for movement between energized and de-energized positions. A diaphragm, mounted in the armature cavity, is connected to the armature. An inlet check valve permits fluid flow in only a first direction moving from an inlet port toward the diaphragm. An outlet check valve permits fluid flow in only a second direction moving from the diaphragm toward an outlet port. A fluid flow path extends through the retainer body from the inlet check valve to the diaphragm and from the diaphragm to the outlet check valve for transporting fluid from the inlet check valve to the outlet check valve as the diaphragm oscillates between first and second positions.

Solenoid pump

A solenoid operated modular valve including a valve body, a valve member slidingly received in the valve body, and a solenoid that moves the valve member relative to the valve body along a longitudinal axis between an open position and a closed position. The valve body has an end face, a side face, and an inner bore. An outlet port in the end face is disposed in fluid communication with the inner bore. An inlet port in the side face is disposed in fluid communication with the inner bore. The valve body includes an O-ring valve seat that is positioned longitudinally between the inner bore and the outlet port. The valve member includes a tapered end that has a frustoconical shape and a valve member abutment surface. The valve member abutment surface contacts the O-ring valve seat when the valve member is in the closed position.

Modular valve with O-ring valve set

A valve including a housing, a valve seat provided in the housing, and an armature assembly positioned in the housing proximate the valve seat. The armature assembly is movable towards and away from the valve seat, and includes a first armature, and a second armature that is movable relative to the first armature. The valve also includes a coil that is configured to actuate the armature assembly away from the valve seat to open the valve, wherein upon application of a first current to the coil, the first armature and the second armature are each actuated away from the valve seat to a first open state, and upon application of a second current that is greater than the first current to the coil, the second armature is actuated away from the first armature to a second open state that is greater than the first open state.

Flow-through liquid 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.

Pneumatic control valve manifold

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.

Multi-port modular valve with snap-in seat

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.

Multi-port normally open modular valve with thread-in seat

A diaphragm sealed, pressure balanced valve assembly includes a valve body and a cartridge connected to the valve body. The cartridge includes a cartridge loading end having a retaining member engaged to the cartridge loading end. A valve member slides coaxial to a longitudinal axis of the valve body. A resilient material first diaphragm is connected to and extends diametrically outward from the valve member having a diaphragm body clasped between the retaining member and the cartridge loading end, creating a first diaphragm fluid pressure boundary. A resilient material second diaphragm is connected to and extends diametrically outward from the valve member at an opposite end of the valve member with respect to the first diaphragm and has a diaphragm body clasped between first and second adjustable retention members, creating a second diaphragm fluid pressure boundary.

Pressure balanced valve with diaphragm valve member end seal

A valve assembly includes a valve body having a valve bore. A valve member is slidably disposed within the valve bore between first and second stop positions. First and second valve elements of the valve member have first and second sealing surfaces equally angled with respect to a valve member longitudinal axis. Each of the first and second sealing surfaces is oriented parallel with conical shaped first and second seat surfaces. Both first and second seat surfaces are equally angled with respect to the longitudinal axis and have an adjustable spacing such that the first sealing surface contacts the first seat surface and the second sealing surface contacts the second seat surface simultaneously in the first stop position.

Piloted poppet valve

A valve assembly includes a solenoid can having an internal coil. A valve body connected to the solenoid can includes an inlet port and a first valve seat. An axially adjustable retainer threadably connected to the valve body includes an end portion defining a second valve seat. A homogenous valve member/armature slidably disposed in the valve body moves in the presence of a coil generated magnetic flux between valve closed and valve open positions. A valve member/armature first surface area is in fluid communication with a pressurized fluid through the inlet port. A valve member/armature second surface area is in fluid communication with the pressurized fluid in the valve closed position. The first surface area is equal to the second surface area and the pressurized fluid acts equally on the first and second surface areas defining a pressure balanced condition in the valve closed position.

Balanced solenoid valve

A pneumatic pressure regulator assembly including a regulator housing having an inlet adapted for fluid communication with a supply of pneumatic pressure, an outlet adapted to provide pneumatic pressure to a downstream pneumatically actuated device at a regulated pressure, and a regulator valve assembly. The regulator valve assembly has a valve member movably supported within the regulator housing between an open and a closed position. A piston assembly acts to bias the valve member to its open position when the outlet pressure is below a predetermined value. The piston assembly includes a pressure responsive surface defining a geometric shape with a major and a minor axis wherein the major axis is greater than the minor axis. The piston assembly is responsive to pneumatic pressure flowing between the inlet and the outlet to reduce the biasing force acting on the valve member such that the valve member moves to its closed position when the outlet pressure exceeds a predetermined value.
