PVLA Suction ValveThe PVLA valve is an accessory available for PVB basic modules.The PVLA will suck fluid from the tank to the work port to prevent cavitation by the 0.5 bar spring. Theplug will ensure that when using a single acting spool, all flow returning through the work port is led totank.PVLA schematicP109175Port pressurePVLP/PVLA suction valve characteristics5 10 15 20 25 30 35 40 45 50 55 60 65 [l/min][US gal/min]70 75 801 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 212018161412108642085 90 95 10022 23 24 25 26Q28262422PP200160120804002802403204003600[psi] [bar]0Q105 110 115 12027 28 29 30 31PVLPPVLATechnical specificationParameter Minimum Recommended range MaximumFluid temperature -30°C [-22°F] 30 to 60°C [86 to 140°F] 90° [194°F]Fluid viscosity 4 mm2/s [39 SUS] 12 to 75 mm2/s [65 to 347 SUS] 460 mm2/s [2128 SUS]Fluid cleanliness 23/19/16 (according to ISO 4406)Operating temperature Ambient: -30 to 60°C [-22 to 140°F]PVLA suction valve part numberPVLA suction valve Plug157B2001 157B2002Technical InformationPVG 16 Proportional Valve GroupPVB Basic Modules Accessories© Danfoss | December 2018 BC00000211en-000901 | 61
