These small but mighty components play a big role in your breast pump’s operation. The yellow valve connects to the flange and holds the white membrane, which flexes with suction pressure to regulate milk flow. This ensures smooth and consistent pumping each time you use it.

Attach the yellow valve to the breast shield, then gently press the membrane onto the valve base until it lies flat. Make sure all pieces are snug before use.

There’s no fixed “dosage”—simply replace the valves and membranes as needed, ideally every few months or when they show signs of wear for continued optimal performance.

• Slight decrease in suction if not properly installed
• Minor stiffness in new membranes
• Potential leakage if parts are worn out or misaligned
