Brass plugs with two breather holes located under the hex head providing adequate
airflow capacity.KMF is equipped with a metal filter inside (filtration50 u) to avoid
pollution of the oil.KMV is used when venting of the reservoir is required in case of
over-pressurisation.The pre-tensioned spring willallow the valve disc to be lifted from
its seat at a pressure of .20-.25 BAR (3-3.6 PSI) allowing the air to escape.When the
pressure is reduced after venting the valve will close and stop air entering the reservoir
and also prevent oil overflow through the plug’s valve due to oil movement whilst in the
closed position.
