Product Information

What Is Silicone NSF Valve?

Non sticking silicone NSF valves are also known as NSF approved silicone valves, which made of FDA & LFGB approved food grade silicone material, meeting the requirements and standards set by the National Sanitation Foundation (NSF). Hopewell produced silicone valves for more then 10 years, also created many public mold silicone valves, also include silicone NSF valves, we can customize any Pantong colors silicone NSF valves for you. Low moq, factory price, factory deliver, high quality.

The Features Of Silicone NSF Valve?

1. Food Grade Material

High precision silicone NSF valves made of food grade safe silicone material, with EU food contact material certificated, and they do not impart any taste, odor, or contaminants to the substances they come into contact with, so silicone NSF valves are very safe to contact with food or beverages.

2. High Temperature Resistant

Because silicone material is high temperature resistant, and can work within -40℃ to 200℃, so silicone NSF valves are suitable for applications where hot liquids or steam are involved.

3. Durable Resistant

Silicone is famours for their durability, so silicone NSF valve can withstand repeated use and are resistant to wear and tear.

4. Leak Proof

FDA certificated silicone NSF valves have passed inverted leak proof test for 7 days* 24 hours, and there is no leakage.

5. High Precision

Silicone NSF valves tolerance of the curved wall thickness is controlled within 0.03mm, the dispensing angle is controlled within 30 degrees, zero clearance and non stick slit cut.

6. One-piece Design

Silicone NSF valves can directly be assemble with plastic ketchup bottles, no need plastic pp ring.

The Advantages Of Hopewell To Produce Silicone Valves?

1. Hopewell, established in 2009, is a company 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 this industry. 

2. Our production facilities span over 6,000 square meters and include a 100,000 clean production workshop and a painting 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 image automatic screening machine 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.
