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 apparatus that includes a valve assembly including a valve retainer body that houses a movable poppet that defines a valve member that is configured to contact a conically shaped valve seat of the valve retainer body; and a motor assembly including a rotatable shaft that is configured to actuate the valve assembly; wherein the rotatable shaft includes a thread formed at an end thereof, the thread being engaged with a sleeve that through rotation of the thread by the rotatable shaft will translate the sleeve towards and away from the movable poppet to transfer an axial force to the poppet that forces the valve member into engagement and disengagement with the valve seat to open and close the valve assembly.
