Multi-port modular valve with snap-in seat

A solenoid operated modular valve, comprising:

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

A solenoid operated modular valve, comprising:

• a solenoid body having a coil and a pole piece positioned in the solenoid body;
• a polymeric material valve body cartridge releasably connected to the solenoid body;
• an armature/valve member slidably disposed in both the solenoid body and the valve body cartridge, the armature/valve member displaced toward the pole piece when the coil is energized;
• a polymeric snap-in seat assembly having:
• first and second deflectable claw arms each having a barb engaging the valve body cartridge to retain the snap-in seat assembly in direct contact with the valve body cartridge;
• a guide tube slidably receiving a valve member guide of the armature/valve member;
• and
• a seat engagement face which when contacted by a valve seal member supported on the armature/valve member defines a valve closed position, the valve seal member displaced away from the seat engagement face in a valve open position when the coil is energized;
• and
• a biasing member acting to normally bias the armature/valve member toward the snap-in seat assembly seat engagement face and acting to create a clearance gap between the snap-in seat assembly and the valve body cartridge in a non-installed condition of the modular valve.
