A valve apparatus including a hollow valve retainer that includes a poppet slidingly positioned therein. The poppet includes a radially inwardly extending groove that is configured for receipt of a quad-ring sealing member that improves the sealing characteristics of the valve apparatus, as well as reduces friction between the poppet and valve retainer to increase the useful life of the valve apparatus.

Valve having a quad ring seal

A valve apparatus that includes a valve assembly including valve body that defines an inlet, a first outlet, and a second outlet, and including a poppet located in the valve body that includes a valve member. An actuator assembly is attached to the valve assembly that includes an armature that is coupled to the poppet and is configured to move the poppet and the valve member to control a flow of fluid through the valve assembly from the inlet to either the first outlet or the second outlet. A diaphragm is located between valve assembly and the actuator assembly that is configured to seal the valve assembly from the actuator assembly.

Pilot valve having diaphragm

A valve including a valve seat assembly that includes a first valve seat sealing member positioned between a first valve seat retaining ring and a first radially inwardly extending flange that extends from an inner surface of a hollow valve retainer, and a second valve seat sealing member positioned between a second valve seat retaining ring and a second radially inwardly extending flange that extends from the inner surface of the hollow valve retainer. A valve member is configured to engage and disengage with the first and second valve seat sealing members to permit fluid to travel from a fluid inlet to a fluid outlet.

Three-way valve

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 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 diaphragm valve includes a solenoid body having a coil and a pole piece. An armature is configured to slide in the solenoid body along a longitudinal axis between energized and de-energized positions. A valve body cartridge is connected to the solenoid body. A valve member, connected to the armature, is configured to slide within the valve body cartridge when the armature moves. A biasing member acts to normally bias the armature toward the de-energized position. A diaphragm, extending inwardly from the valve body cartridge towards the valve body, is received between the armature and the valve member. A diaphragm support sleeve includes a support sleeve wall defining a sleeve cavity that receives the armature and a support sleeve flange that extends inwardly from the support sleeve wall to abut and support at least part of the diaphragm.
