The R.OL.TMDV-DS dual-valve breather filler cap has been specially developed for hydraulic applications where reservoir pressure must be controlled under both positive and negative pressure conditions. The integrated dual valve releases air in a controlled manner when overpressure occurs and allows air to enter the reservoir when a vacuum develops. This prevents reservoir deformation and maintains balanced internal pressure. The Polyamide 66 housing and integrated 40-micron air filter protect the hydraulic system from contamination.
