        Large diameter gate valve

        Large diameter gate valve

        The large-diameter gate valve is applicable to the small-diameter pipeline with the operating temperature of - 29-425 ° C (carbon steel) or - 29-500 ° C (stainless steel) in Class 150-2500. The large-diameter gate valve is used to close or connect the medium in the pipeline. Use different materials that can be applied to different media (such as water, steam, oil, nitric acid, acetic acid, oxidizing media and urea). It is widely used in oil pipelines.

        Large diameter gate valve is a new type of valve. It has the structure of soft seal and hard seal. The soft seal consists of a movable valve seat and a replaceable rubber ring, so it is easy to replace the worn seal ring. The large-diameter gate valve completely makes up for the inconvenience caused by PTFE sealing and processing in the past.

Various types of check valve products can be installed according to user needs. The large diameter check valve conforms to the hydraulic contour design, and the streamlined water channel and internal reverse fluid design can reduce the pressure loss in the pipeline.

        Large diameter check valve is usually installed at the outlet of large water pump. It can be quickly closed before the water flow reverses to prevent water hammer, water hammer noise, destructive impact, achieve the purpose of silence, prevent medium backflow and protect the equipment.
