  Silicone valves are essential components used across a wide range of industries, from food and beverage to medical devices, home appliances, and personal care products. Known for their flexibility, durability, and excellent sealing properties, silicone valves help regulate fluid, gas, or powder flow under specific pressure conditions. In this article, we’ll explore what silicone valves are, the different types available, where they’re used, and why custom silicone valve manufacturing is key to performance and reliability. What Are Silicone Valves? Silicone valves are elastomeric one-way or two-way valves made from high-quality silicone rubber. These valves are engineered to control the flow of liquids, gases, or powders based on applied pressure. Under no pressure, the valve remains sealed; when sufficient pressure is applied, it opens to allow controlled dispensing or venting. They are typically produced using: Compression molding Liquid injection molding (LIM) Silicone valves...
