Product Description
9.8 mm Silicone Fluid Control Valve for No-Flip-Cap Dishwashing Liquid Bottles& Soap Dispensers
Our 9.8 mm silicone fluid valve is specially engineered for no-flip-cap dishwashing liquid bottles. These bottles typically have a 28-410 neck size, which limits the space available for the valve. To maximize performance within this compact design, we manufacture the valve with the smallest possible outer diameter while maintaining optimal flow control.
The bottle design allows for inverted storage, so the valve's thickness and precision-cut cross slit are carefully optimized to prevent leakage when upside-down. At the same time, the valve ensures smooth, consistent dispensing, matching the customer's desired flow volume and dispensing angle, and enabling quick air re-entry for the next squeeze.

Key Features
⒈ Compact 9.8 mm Outer Diameter – Fits standard 28-410 neck closures.
⒉ Leak-Proof Inverted Storage – No dripping even when stored upside-down.
⒊ Optimized Cross Slit Design – Balances opening pressure, flow rate, and dispensing angle.
⒋ Fast Air Recovery – Ensures quick reset for the next squeeze.
⒌ Consistent Flow Control – Maintains uniform output under constant pressure.
⒍ Customizable Hardness – Options for different liquid viscosities.
Why Design Matters
A silicone valve is more than just a sealing element — it is a functional fluid control component.
⑴ Pressure-activated: Opens only when the applied squeeze pressure reaches a precise threshold.
⑵ Consistent dosing: Delivers an accurate amount of liquid under constant pressure.
⑶ Strict dimensional tolerances: Prevents variation in opening pressure, flow angle, and dispensing volume.
If the valve dimensions deviate, it can result in inconsistent opening pressures, irregular flow patterns, and uncontrolled liquid volume. That's why our production follows tight tolerance standards to ensure every valve performs reliably.
Target Applications
◎ No-flip-cap dishwashing liquid bottles
◎ Inverted storage cleaning product dispensers
◎ Kitchen cleaning brush and dishwashing brush soap reservoirs

FAQ
| 1. What is a silicone fluid valve and how does it work? A silicone fluid valve is a precision-molded silicone component designed to control liquid flow in dispensing applications. It stays closed under normal conditions and only opens when a certain squeeze or pressure threshold is reached, ensuring leak-proof, controlled dispensing. |
| 2. Why choose a 9.8 mm silicone fluid valve for no-flip-cap dishwashing bottles? The 9.8 mm outer diameter is ideal for 28-410 bottle closures, which are commonly used for no-flip-cap designs. It allows maximum flow control within limited space, ensuring both leak prevention and smooth dispensing. |
| 3. How does the valve prevent leaks during inverted storage? The valve's thickness and precision-cut cross slit are engineered to remain sealed under the bottle's own weight. This ensures no-drip performance even when the bottle is stored upside down. |
| 4. Can the silicone fluid control valve be customized for different liquids? Yes. We can adjust the slit size, hardness (Shore A), and opening pressure to match the viscosity and dispensing needs of different cleaning solutions or detergents. |
| 5. What materials are used and are they food-safe? Our valves are made from FDA & LFGB certified liquid silicone rubber (LSR), which is safe, durable, and resistant to chemicals used in dishwashing and cleaning products. |
