Backflow prevention valve / Check valve CV series [2D/3D CAD]
CV
A backflow prevention valve that can be used in gas piping for combustion equipment such as city gas and LPG. It operates at low differential pressure and prevents backflow of combustion air.
【Purpose】 Prevention of backflow in gas lines 【Features】 It operates even at low differential pressure due to its structure with low pressure loss. Available for pipe sizes from 15A to 100A. Installation can be done in the "horizontal direction" and in the "vertical direction with flow from bottom to top." 【Gas Used】 - City gas (13A) - Propane (LPG) - Please inquire for other gases. *Please refrain from using with air or oxygen piping as it contains NBR. CAD drawings are also available for download. 2D (DXF), 3D (STEP)
