CHECK VALVE CARTRIDGE WITH SPRING

摘要

PURPOSE: To provide a small-sized reversible spring check valve used when it is necessary in a fluid pump to equip a check valve having a particularly small volume and a minimum depth. CONSTITUTION: In this reversible check valve, a sealing disc 5 is pressed to the shutoff position by an umbrella-shaped spoke-like spring fixed to a cage 10 so as to permit the full travel of the sealing disk within the case, whereby the flow rate can be increased to a given thickness of a valve cartridge 2.
