The breather valve is installed above the hydraulic oil tank. It is mainly used to balance the air pressure inside and outside the hydraulic oil tank during the output and inflow of hydraulic oil from the oil tank. It can not only maintain the pressure of the oil tank, but also dissipate heat. The pressure can be released manually through the breather valve. Prevent air pressure impact when opening the oil tank. At the same time, the breather valve can also filter the dust and other impurities in the atmosphere. Ensure that the cleanliness of hydraulic oil is not polluted by external dust.
