Silicone valve is a kind of one-way or check valve made from silicone rubber (elastomer) that controls the flow of fluids (liquids or gases) by opening under a specific pressure to allow forward flow and then automatically closing to prevent backflow.It is typically have no moving internal parts like a ball, disc, or stem. Instead, the entire valve body itself is flexible and performs the sealing action.
Features a cross-shaped slit. It can achieve “forward pressure for dispensing, negative pressure for air return.”by silicone elasticity. Widely used in sauce bottles, sport water bottles, shampoo bottles for controlled dispensing and leak prevention.
Shape likes a duck’s beak with a linear outlet. The valve has clear directionality, it opens with forward pressure and closes tightly with reverse pressure. Widely used in medical devices, anti-siphon check valves, respirators where critical backflow prevention.
Shape likes an umbrella. Usually used for ventilation and pressure relief, when reaching a certain pressure difference , the edge of the umbrella surface lifts to allow gas or liquid to pass through.
A flat silicone membrane,widely used in precision control diaphragm valves for sealing and flow regulation.

25年以上にわたる開発および製造の実績
Offer design,technology,production support.
ISO9001、ISO14001、ISO13485およびFDAの認証取得
Complete production equipment and environment
Silicone valve which made from food grade silicone material meets FDA or LFGB.
Made from medical grade silicone material,the valve is able to meet ISO10993 biocompatibility requirement.
Industrial grade silicone or specialty materials (like FVMQ) can offer greater chemical resistance, oil resistance, and durability.
The silicone valve is widely used in medical devices like respiratory masks and circuits, baby care like breast pump, beverage like beverage dispensing system ,industrial like pumps,personal care like lotion and other household appliances.
Cross-slit valves, duckbill valves, umbrella valves, and dome valves etc.
Both of them are available from OTI.It depends on customer’s design and application.
