Product Description

One-Way Valve (Check Valve) Product Overview
Inspired by the functional and design principles of medical check valves, this one-way valve ensures unidirectional fluid or gas flow while preventing backflow. Its compact, lightweight, and durable construction makes it ideal for applications requiring precision and reliability.

Key Features & Design

1. Structure:

   • Valve Body: Engineered with high-grade polymers (e.g., nylon or polypropylene) for chemical resistance and longevity.
   • Sealing Mechanism: A flexible silicone or rubber diaphragm acts as the primary sealing component, responsive to pressure differentials.
   • Spring-Assisted Closure (optional): Enhances sealing efficiency in low-pressure environments.

2. Appearance:

   • Flat, low-profile circular design (typically 10-25 mm in diameter) with a smooth surface for seamless integration into systems.
   • Color options include translucent/white for visibility or black for UV resistance.

 

Operation Principle

• Forward Flow: Positive pressure from the inlet flexes the diaphragm, allowing flow.
• Reverse Flow: Backpressure forces the diaphragm against the valve seat, creating an airtight seal.

 

Applications

• Inflatable products (e.g., airbeds, life vests, rafts).
• Medical devices (e.g., respiratory equipment, fluid drainage systems).
• Industrial fluid/gas control systems.

 

Optional Manual Relief Function
Some models include a central depressible pin for controlled deflation, enabling rapid gas release without compromising valve integrity.

 

Advantages

• Leak-proof performance even under variable temperatures (-30°C to +80°C).
• Low cracking pressure (<0.5 PSI) for sensitive systems.
• Maintenance-free and corrosion-resistant.

 

This valve combines practicality with robust engineering, mirroring the trusted performance of medical designs while adapting to modern technical demands.
