To be installed at pipelines that carry nitrogen-hydrogen-ammonia mixtures to prevent backflow of medium.
When fluid flow coincides with the direction of the arrow, it compresses spring and moves disc to allow fluid to pass through. When fluid is supplied no longer, spring locks disc and prevents back-flow of fluid.
Working medium temperature: up to +200оС
Bore: DN 32 , nominal pressure PN 32 МPa
Body material: 20Х Steel. Permitted is valve use in other media which are not corrosive for body material.
Connection to pipeline: flanged with lens seal.
The valve may operate in regions with temperate or tropical climate in the open air under direct effect of atmospheric precipitation.
