| The H77-16C wafer-type double-flap butterfly one-way check valve is a uniquely designed and excellent performance check valve, designed to meet the high requirements for one-way flow control of fluids in modern industrial pipeline systems. The valve adopts a wafer-type connection method, which is not only easy and quick to install, but also does not require additional flanges and bolts, greatly saving installation space and costs. The double-flap butterfly valve disc structure enables the valve to open quickly when the fluid flows, and to close quickly when the fluid stops or flows back, effectively preventing the backflow of the medium and ensuring the safety and stable operation of the pipeline system. The valve body is made of high-quality cast iron or cast steel material, with good corrosion resistance and wear resistance, and is suitable for various corrosive or non-corrosive media pipeline systems. The H77-16C wafer-type double-flap butterfly one-way check valve is widely used in water supply and drainage, HVAC, fire protection, petrochemical and other industrial fields, and has become an indispensable and important component in 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. |
