Customized 16mm Silicone Check Valve

Specification of Customized Silicone Check Valve for Soap Dispensing Brushes

What is a Silicone Check Valve for Soap Dispensing Dish Brushes?

This silicone check valve is a precision sealing component for dish brushes, enabling accurate one-way soap dispensing through a micro-slit design. Manufactured via high-precision LSR injection molding, it guarantees critical dimensional tolerances: ±0.05mm for wall thickness and ±0.1mm for slit size. Its low-pressure activation design ensures reliable soap evacuation with minimal residue, eliminating failure to dispense at near-empty states. This delivers consistent leak-proof performance and dispensing accuracy.

The Advantages of Silicone Check Valve for Dish Brushes

1. Food Grade Material

The 16mm silicone check valve for brushes is made of food-grade liquid silicone, which resists soap corrosion and avoids contaminating dishwashing soap.

2. Leak Proof and Spill Proof

The silicone check valve is leak-proof and spill-proof. One squeeze, one dispensing, no leakage, and no waste of soap.

3. Reusable

Silicone is famous for its durability, so the silicone check valve can withstand repeated use and is resistant to wear and tear. The silicone check valve can endures 500,000+ compression cycles.

4. Low MOQ

Hopewell provides silicone check valve at high-quality with a low MOQ and factory price.

5. High Precision

With the capability for precision mold design & manufacturing and extensive experience in precision production management, we can precisely maintain the tolerance for the elastic wall thickness of the silicone check valve within ±0.05 mm.

6. One-piece Design

The silicone check valve can be assembled directly with soap dispensing brushes; no additional components are needed. Its high reliability and resistance to malfunction allow the valve to endure over 5000 compression cycles.

The Advantages of Hopewell to Produce Silicone Valves

1. Our factory is established in 2009, specializing in the research and development as well as production of silicone rubber products. With over a decade of experience, we have built a strong reputation in industry of silicone molding. 

2. Our production facilities span over 6,000 square meters and include a 100,000 clean production workshop and a surface treatment workshop. 

3. With in-house precision mold design and mold making department. 

4. High-precision mold processing equipment imported from abroad has stable quality and the slit cut size can be controlled within ±0.05MM, effectively eliminating the tilt of the liquid outlet angle caused by eccentricity.

5. Independently developed automated silicone valve punching equipment, incision, appearance, and opening confirmation are all completed on one machine. In case of abnormal opening, the equipment will automatically alarm and shut down, ensuring 100% incision quality.

6. All our silicone valves use an AOI (Automated Optical Instrument) for quality inspection, which can confirm all defective contents such as burrs, missing flushes, missing materials, bubbles, etc. one by one, and automatically reject defective products.
