Rubber Umbrella Valve
Our umbrella valve, also known as a duckbill or umbrella check valve, is meticulously crafted from high-grade silicone rubber, offering superior elasticity, corrosion resistance, and mechanical strength. It plays a crucial role in systems where reverse flow must be strictly avoided, such as in fluid control, vacuum systems, medical devices, and industrial equipment.The valve operates based on a simple yet highly effective mechanism: under normal flow conditions, the "umbrella" opens to allow media passage, and upon pressure reversal or cessation, it automatically closes to prevent backflow. Its self-sealing design ensures minimal maintenance and long-term reliability.
Key Features
- Custom Processing: We offer full customization services to meet specific dimensional, functional, and aesthetic requirements. Whether you need a particular shape, size, or color, we can tailor the product accordingly.
- High Seal Integrity: The valve’s unique structure combined with premium silicone material ensures airtight and watertight sealing performance, even under fluctuating pressures.
- Chemical Resistance: Our proprietary rubber compound formulation enhances the product's ability to withstand exposure to aggressive chemicals, solvents, and cleaning agents, making it suitable for use in harsh environments.
- Durable & Wear-Resistant: Engineered for longevity, the valve maintains consistent performance over time, resisting abrasion, aging, and deformation.
- Environmentally Friendly: Compliant with international environmental standards, our products are non-toxic, odorless, and recyclable.
- Easy Installation & Maintenance: Designed for user-friendly integration into existing systems, the valve requires no complex tools or procedures for installation or upkeep.
- Advanced Manufacturing Capabilities: With state-of-the-art mold processing equipment—including CNC machining, engraving, and milling—we ensure precision in every component. Our production process integrates drawing design, mold development, and mass production, significantly reducing lead times without compromising quality.
- Professional Quality Assurance: Equipped with comprehensive testing facilities and collaborating with third-party inspection agencies, we provide detailed test reports including tensile strength, compression set, chemical resistance, and more. Each batch undergoes strict quality control to guarantee compliance with industry standards.
Material Innovation
We develop our own rubber compound formulas through extensive R&D, allowing us to fine-tune properties such as hardness, elongation, temperature resistance, and color. This in-house capability enables us to produce valves that perform optimally in diverse conditions—from extreme cold to high-temperature environments—and across a wide range of industries.
Applications Across Industries
Due to its versatile material characteristics and robust sealing function, the umbrella valve finds application in numerous fields:
- Medical Equipment: Ensuring sterile airflow and preventing contamination in ventilators, oxygen concentrators, and anesthesia machines.
- Industrial Machinery: Used in pneumatic systems, hydraulic equipment, and automated manufacturing lines.
- Automotive Industry: Installed in engine components, emission control systems, and fluid transfer mechanisms.
- HVAC Systems: Maintaining directional airflow and preventing backdrafts in heating, ventilation, and air conditioning units.
- Water Treatment: Preventing sewage or chemical backflow in filtration and pumping stations.
