Product Introduction

GYH41X-16 flange typeSilencing check valveWidely used in pipeline systems such as water supply and drainage, fire protection, refrigeration, oil depots, etc.

GYH41X-16 flange type soundproof check valve is used to prevent liquid backflow in pipelines. Before the medium flows back, the valve disc is closed in advance by the action of the spring, effectively preventing the generation of water hammer and reducing the noise of valve operation. The valve body adopts an enlarged inner cavity and streamlined design, greatly reducing flow resistance. Both vertical and horizontal installation are acceptable.
