Product Description

Silicone Duckbill Valve: The Ultimate Solution for Accurate Hand Sanitizer and Liquid Soap Dispensing

Silicone duckbill valves are one-way valves that allow fluids or air to flow in one direction only. They are commonly used in automatic soap dispensers, manual soap dispensers, and other liquid dispensing systems. Silicone duckbill valves are made from high-quality silicone material that is resistant to wear and tear, heat, high and low temperatures. This means that they can withstand frequent use and exposure to harsh environments without deteriorating or breaking down.

Product Information

Silicone duckbill valve helps to prevent leaks and spills. The valve is designed to create a tight seal around the dispenser nozzle, which prevents soap from dripping out when the dispenser is not in use. This not only helps to reduce waste but also helps to keep the surrounding area clean and hygienic. The valve is designed to open and close in response to changes in pressure, which helps to regulate the flow of liquid soap. This ensures that the dispenser dispenses the same amount of soap each time it is used, which can help to reduce waste and save money in the long run.
