Overview

Meet IVARONAL’s 10-piece duckbill valve set, designed to accompany a range of popular breast pumps with a focus on clean, dependable performance. The valves are crafted to feel soft and gentle against skin while delivering a calm, steady pumping experience. This upgrade is intended to fit several models across well-known brands, helping you streamline parts and keep pumping sessions efficient.

Compatibility at a Glance

The valves are designed for broad compatibility across top pumps, including Lansinoh Discreet Duo, Eufy E10/S1/S1 Pro, and S32 wearable pumps. They also fit S32/S21/S18 models and are compatible with a variety of third-party parts from brands like NCVI, NICEGREEN, Nuliie, Zooawa, and Sunnaltree. This versatility makes it easier to find a reliable replacement when needed, without hunting for a single-brand option.

• Fits Lansinoh Discreet Duo and Eufy S1 Pro/S1 E10 for flexible setup.
• Suitable for S32 wearable pumps and related S21/S18 configurations.
• Broad compatibility with NCVI, NICEGREEN, Nuliie, Zooawa, and other popular brands.

What Makes These Valves Stand Out

Key benefits come from a thoughtful, closed-system design paired with safe materials. The top of each valve is sealed to direct milk toward the container, helping minimize spills and keeping pumping sessions tidy. The design supports a smooth flow that many users find easier to manage, while maintaining a seal that can help reduce drips during use.

• No Backflow, Non-Leaking: A sealed top directs milk downward, promoting a cleaner pumping experience.
• No-Loss, Efficient Pumping: The parts perform in a way that can feel similar to OEM components, with smooth milk flow and steady suction.
• Food-Grade Silicone: Soft, odorless, and skin-friendly for mother and baby comfort.

Care, Cleaning, and Everyday Use

Maintenance is straightforward: these valves and the silicone diaphragm can be sanitized using water steam, boiling water, or microwave-steam bags after each use. For best results, use boiling water or steam at around 100°C (212°F). The soft silicone remains gentle over time, preserving comfort during frequent pumping sessions.

• Sanitize with steam, boiling water, or microwave-steam bags at ~100°C (212°F).
• Easy to reassemble and reuse between pumping sessions with proper cleaning.

Use these valves to support your pumping routine with a focus on reliability, ease, and material safety. While not a medical claim, many caregivers and users appreciate the combination of compatibility, clean design, and straightforward maintenance as part of a well-rounded pumping setup.
