Food Grade Liquid Silicone One Way Inverted Valves Suppliers

Overview

Our food-grade liquid silicone one-way inverted valves ensure reliable, contaminant-free flow control for packaging and dispensing systems. Engineered from certified LSR via precision injection molding, these valves allow controlled forward flow while preventing backflow. We offer full OEM customization of size, cracking pressure, and design to meet your specific application requirements.

Characteristics

OEM Process for LSR Inverted Valves

1. Application & Specs Submission: Share your assembly design, flow direction, media, and pressure requirements. Provide any interface drawings (STEP, IGS).

2. Engineering & Flow Analysis: We analyze the mounting configuration and fluid dynamics to design the inverted valve geometry, followed by a technical quotation.

3. Prototype & Functional Testing: We produce functional prototypes integrated into your assembly for real-world backflow prevention and flow testing.

4. Approval & Production Agreement: Upon prototype approval, a proforma invoice is issued for the production mold and order deposit.

5. Precision Mold & T1 Sample: Multi-cavity LSR molds are fabricated. T1 samples are provided with performance validation data.

6. Mass Production & 100% QC: Full-scale production begins. Each valve undergoes 100% automated leak testing (forward & reverse flow verification).

7. Delivery: Valves are packaged to prevent deformation and shipped.
