ANGODOS AG1-R is a butterfly check valve, full bore with flanged body

ANGODOS AG1-R is a butterfly check valve, full bore with flanged body. The valve is available from DN200 to DN1500 The sealing gasket is the key for reliable sealing performance and it’s placed in the body. The disc is attached to the eccentric (simple or double) shaft bearing assuring an uniform seat and avoiding critical leaking by pressure discontinuities at the sealing area. In this way sealing system assures perfect sealing under the most demanding conditions. Full bore and hydrodynamic internal design provides outstanding hydrodynamic features minimizing the head loss. Automatic closing happens when the flow direction changes because of the offset and the counterweight. The end of the closing movement can be optionally damped The valve offers maximum safety due to the mechanic design, working without the need of any energy source.
