·High-strength, corrosion-resistant, impact-resistant: the valve core is built with stainless steel plate, and the exterior is made of corrosion-resistant and impact-resistant reinforced composite engineering plastics.
·Good passability: the reverse check valve core is adopted, the cavity is smooth, so it is not easy to be blocked.
·Fast water stop: Swing type opening and closing structure, operation fast.
·Convenient maintenance and replacement: the check valve body is provided with a drain hole, which can quickly empty the sewage in the pipeline when the check valve is disassembled; the check valve is integrated on the water outlet of the equipment, which is convenient for disassembly and installation.
