Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 and ISO9001 certified, is proud to introduce our Low Vibration High Velocity Relief Valve designed specifically to prevent flame ingress into liquid cargo tanks. This valve combines advanced engineering with robust construction to ensure reliable overpressure protection while minimizing vibration and maintaining high flow capacity. With annual export values ranging from US$1 million to US$1.5 million and a global reach spanning North America, Europe, Asia, and more, our commitment to quality and safety is backed by years of specialized manufacturing experience.
Our relief valve is engineered to meet the demanding requirements of the maritime and storage industries, where cargo tank integrity and fire safety are paramount. The unique design effectively suppresses flame propagation through the valve, even under high-velocity discharge conditions, making it an essential component for liquid cargo handling systems. Whether for tankers, storage terminals, or process vessels, this valve delivers exceptional performance with minimal maintenance.
Key Features & Technical Specifications
- Low Vibration Operation: Advanced internal geometry reduces turbulence and mechanical vibration, extending valve life and reducing noise.
- High Velocity Relief: Optimized flow path allows rapid pressure release without compromising sealing integrity.
- Flame Ingress Prevention: Integrated flame arrestor element (tested per industry standards) stops flame from entering the cargo tank during relief events.
- Corrosion-Resistant Materials: Available in stainless steel or carbon steel with optional coatings to suit aggressive cargo media.
- Customizable Settings: Set pressure from 0.1 bar to 10 bar (or as required) with adjustable spring-loaded mechanism.
- Durable Sealing: PTFE or metal-to-metal seat options for leak-tight performance over a wide temperature range.
