Metering Valve Part Sequence: Key Components
The question asks to arrange the components of an aerosol metering valve in a specific order. The components are:
- A. Outlet valve seal
- B. Capillary dip tube
- C. Inlet valve seal
- D. Two-piece stainless steel stem
Understanding the function and typical arrangement of these parts is key to sequencing them correctly.
Sequencing the Valve Components
The correct sequence involves identifying the central functional elements and their order of operation or assembly:
- D. Two-piece stainless steel stem: This is the core moving part that actuates the valve mechanism, controlling both filling and dispensing.
- A. Outlet valve seal: This seal is critical for ensuring the accurate dispensing of the metered dose by sealing the exit path until actuation.
- C. Inlet valve seal: This seal controls the entry of the formulation into the metering chamber from the bulk container, ensuring proper filling.
- B. Capillary dip tube: This tube acts as the conduit, delivering the liquid formulation from the bulk storage to the valve mechanism inlet.
Therefore, the proper order is D, A, C, B.
