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 spring loading. Its quick closing can effectively reduce the water hammer pressure, has good sealing performance, and has no noise when closing. It has the advantages of small volume, light weight, fatigue resistance and long service life.
