Product Description

H44H-150LB American Standard Swing Check Valve is a valve that can automatically prevent fluid backflow, which is used in pipeline systems to prevent media backflow, prevent the pump and its drive motor from reversing, and the medium in the container from draining. The H44H American Standard Swing Check Valve is manufactured to American API Standard and can be installed in unlimited locations, usually in horizontal lines, but can also be installed in vertical or inclined lines. The disc of the swing check valve rotates around the rotating axis, and its fluid resistance is generally smaller than that of the lifting check valve, which is suitable for large-diameter occasions. According to the number of discs, it can be divided into three types: single-lobe swing check valve, double-lobe swing type and multi-lobe swing type. American Standard check valves are designed and manufactured to meet the requirements of the American National Standard ANSIB16.34 and the American Petroleum Institute Standard API 16D. The check valve disc is swing type, the flow channel is straight, and the horizontal pipeline and vertical pipeline can be installed; The swing check valve rocker pin shaft adopts a built-in structure, which reduces the shortcomings of external leakage. It is widely used in petroleum, chemical, pharmaceutical, power industry and other working conditions as a device to prevent the reverse flow of media.

Product Features

1. The design and manufacture of the product meets the requirements of the American national standard ANSI B16.34 and the American Petroleum Institute standard API6D, with reliable sealing and excellent performance. 2. Compact and reasonable structure design, beautiful shape. 3. The valve body has a complete range of materials, and the packing and gasket are reasonably selected according to the actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions. 4. The valve disc can automatically close under the action of gravity to prevent the medium from flowing back. 5. The water hammer pressure is small, the valve disc stroke is short, there is a spring to assist the closing, and the switch is rapid. The structure is short in length, small in size and light in weight.
