Description:
Our precision-engineered silicone dispenser valves are manufactured from 100% FDA-compliant, food-grade liquid silicone rubber (LSR) to deliver consistent flow control and leak-proof performance for viscous liquids like honey, syrup, and condiments. Utilizing LSR injection molding with ultra-precise tooling, these valves feature a self-sealing, one-piece design that prevents dripping, ensures portion control, and withstands repeated compression cycles. Rated for temperatures from -40°F to 400°F and compatible with automated filling systems, they exceed LFGB, FDA, and RoHS standards. As your dedicated manufacturing partner, we offer end-to-end OEM solutions—including custom valve dimensions, flow rates, durometer hardness (Shore A 30-50), and logo imprinting—backed by high-volume production capabilities. Ideal for packaging brands seeking sustainable, reusable alternatives to plastic components.

We utilize Shore A durometers for hardness consistency, FTIR spectroscopy for material purity, and cleanroom assembly to ensure hygiene. All valves undergo batch-level traceability and comply with ISO 9001 and IFS Food standards.
