Flexible opening and closing: the rotary check valve is opened and closed by rotating the valve disc, with flexible operation, quick response, and no water shock phenomenon.

High reliability: forged steel check valve has rapid, flexible opening and closing characteristics, can quickly close off under reverse pressure, and prevent the reverse flow of fluid.

Strong structure: forged steel check valve adopts forging process, the structure is firm, can withstand large pressure impact and vibration, has a long service life.

The double plate check valve has a two spring loaded plate design to open to release medium and bounce back to prevent external leakage. This effective check valve can be installed from any location, providing a tight seal and guaranteed no pressure loss.

Such valves can be assembled in horizontal and vertical lines. The sealing surface of the disc and seat is made of alloy steel or hard alloy. With high temperature resistance, corrosion resistance, wear resistance, long service life characteristics.

The valve body has a complete range of materials, and the packing and gaskets are reasonably selected according to actual working conditions or user requirements, and can be applied to various pressure, temperature.

The product complies with the national standard GB12235, with reasonable structure, reliable sealing, excellent performance and beautiful appearance.

Globe valves are used in chemical industry, petrochemical, petroleum, paper making, mining, electric power, liquefied gas, food, pharmaceutical, water supply and drainage.

he sealing surface is not easy to wear and abrasion, good sealing, opening and closing of the valve flap and the valve body sealing surface of the valve body without relative sliding.
