Two Way Duckbill Spring Non Return Control Safety Mini Rubber Check Valve

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Two-Way Non-Return Control: Designed to regulate fluid flow in two directions while preventing backflow, ensuring safety and efficiency in industrial systems.
  • Duckbill Spring Mechanism: Combines flexible rubber construction with spring-assisted functionality to maintain tight seals under varying pressure conditions.

Key features

  • 1. Material Technology

    • With corrosion-resistant rubber construction, ensure reliable operation in harsh industrial environments. The rubber material offers superior flexibility and durability compared to rigid plastic alternatives, resisting wear and tear in high-stress applications.

  • 2. Interactive Design

    • With the duckbill spring mechanism, achieve automatic non-return flow control without manual intervention. The dual-directional design allows seamless bidirectional flow regulation, outperforming single-use valves in complex systems.

  • 3. Performance Parameters

    • With a compact, miniaturized form factor, integrate easily into tight industrial spaces while maintaining high-pressure tolerance (up to 150 PSI). The molded rubber ensures airtight seals, minimizing leakage risks in fluid systems.

  • 4. Scenario Solutions

    • Designed for continuous industrial use, prevent backflow in critical systems like HVAC, plumbing, or machinery. The safety-focused design ensures fail-safe operation in scenarios requiring uninterrupted fluid or gas flow, such as chemical processing or pressure-sensitive equipment.

  • 5. Certification Standards

    • With RoHS certification, comply with global environmental and safety regulations, eliminating hazardous substances in materials. This ensures safer handling and disposal compared to non-certified alternatives.
