| HH49X-10Q micro-resistance slow-closing butterfly-type one-way check valve is a high-performance check valve designed for pipeline systems that require slow-closing functions. The valve adopts a butterfly structure, and the valve disc automatically opens when the fluid flows, and slowly closes after the fluid passes through, effectively reducing the impact force and water hammer phenomenon when the medium flows back, and protecting the safety of the pipeline system. The micro-resistance design makes the resistance generated by the valve when closing extremely small, reducing energy consumption and noise. The valve body is made of high-quality stainless steel or cast steel, with good corrosion resistance and wear resistance, and is suitable for pipeline systems with various corrosive media. HH49X-10Q micro-resistance slow-closing butterfly-type one-way check valve is widely used in industrial fields such as water supply and drainage, fire protection, and petrochemical, especially in occasions where it is necessary to prevent medium backflow and water hammer phenomenon, such as water pump outlets, fire protection pipelines, etc. Its excellent performance and stable operating status provide a strong guarantee for the safety and stable operation of the pipeline system. |
| Technical parameters Nominal pressure: PN100 Applicable media: non-corrosive or weakly corrosive media such as water, oil, and steam Working temperature: -29ºC~425ºC Connection method: flange connection Valve body material: carbon steel, alloy steel, etc. Valve disc material: the same or more corrosion-resistant material as the valve body Sealing surface material: wear-resistant material such as hard alloy surfacing |
| Product features: Compact structure: straight-through design, small fluid resistance, strong flow capacity. Reliable sealing: adopts metal hard sealing structure, the sealing surface is welded with hard alloy, with excellent wear resistance, ensuring long-term operation without leakage. Flexible opening and closing: the valve disc lifting design, the opening and closing action is fast and smooth, and the ability to respond to changes in the flow direction of the fluid is strong. Easy maintenance: easy to install and disassemble, easy for daily maintenance and repair. Strong applicability: suitable for various high-pressure, high-temperature and corrosive media pipeline systems, with a wide range of applications. |
| Application: Widely used in high-pressure pipeline systems in industrial fields such as petroleum, chemical industry, electric power, metallurgy, water supply and drainage, especially in situations where it is necessary to prevent medium backflow, protect pump equipment, and maintain unidirectional flow in the pipeline system, such as the hydrocracking unit of the refinery, the synthetic ammonia unit of the chemical plant, and the boiler water supply system of the power station. |
