brief introduction

This product is used as one-way opening and closing valve to prevent reverse flow of medium on industrial pipeline. It can be installed horizontally or vertically. The flow direction of medium is consistent with the direction of valve body. The valve disc is guided by the central shaft at both ends of the inlet and outlet, with flexible opening and closing and elastic loading. Its quick closing can effectively reduce the water hammer pressure, has good sealing performance, and has no noise when closing. It has small volume. It has the advantages of light weight, fatigue resistance and long service life. Groove connection can improve the speed of pipeline installation and disassembly, save time, and achieve the effect of fast, convenient, safe and firm. Compared with other valves, it can save 90% of the installation time. It does not need the complicated process of welding and bonding, and does not need to use other machines. It is time-saving, labor-saving, simple, convenient and safe.
