Key Features of Silicone One-Way Umbrella Valve
Medical safe food-grade silicone raw material
High-purity transparent silicone meets medical ISO13485 and food LFGB standards, odorless and non-toxic, safe for direct contact with breast milk, drinking water and human body liquid.
Reliable umbrella one-way anti-backflow structure
Umbrella flap automatically opens under liquid pressure and tightly seals when pressure disappears, effectively blocking liquid and air backflow to keep equipment suction stable.
Low opening pressure & sensitive rebound performance
Soft silicone design requires tiny pressure to open, maintains consistent flow during pumping; millions of opening-closing cycles without losing elasticity or leaking.
Wide range of size customization
Multiple standard sizes in stock, custom disc diameter, stem length and wall thickness available to fit maternal, medical and daily water appliance product lines.
