We have a design on an influent pump station at the start of a wastewater treatment plant that uses Check and Plug Valves on the discharge side of the pumps. I need to know why plug valves are better for this operation versus using gate valves? Thanks.
To help clarify, the blower is sitting below the water level of the filter. To prevent backflow into the blower (when it is off), the pipe elevation was routed above the water level. We decided to add a normally open solenoid valve at the top elevation point of the pipeline. The valve is linked...
I have a blower design for air scouring purposes with pipeline to a gravity filter. I need an inverted "pea-trap" on the line to go above the hydraulic grade line of the filters water level (to create an air gap). The pipeline also has a double wafer check-valve and butterfly valve...
