The valve housing comprises a valve inlet, a valve outlet, a housing wall and an aperture extending through the housing wall between the valve inlet and valve outlet. The dart valve further comprises a valve cartridge. The valve cartridge comprises a cartridge housing configured to allow fluid to flow therethrough from a cartridge inlet to a cartridge outlet; and a valve plunger slidably mounted in the cartridge housing and configured to selectively allow fluid to flow from the cartridge inlet to the cartridge outlet. The valve cartridge is configured to be inserted through the aperture for removably mounting the valve cartridge within the valve housing, in a mounted position, such that the valve inlet is in communication with the cartridge inlet, the cartridge outlet is in communication with the valve outlet and fluid is able to flow from the valve inlet to the valve outlet through the valve cartridge.
