Filler plug KMV with one-way check valve

Brass filler cap with flat fiber gasket.
Two breathing holes located under the hexagonal head provide aadequate air flow.This version is used when it is necessary to vent the tank only in case of internal overpressure.
The valve’s pre-compressed spring allows the disc to be released from its seat at a pressure of 0.4 bar/5.8 PSI, allowing air to escape and thus reducing the pressure inside the tank. Once the pressure is reduced, the valve closes, preventing both the circulation of air and the accidental release of oil due to movement.
These plugs are used in reducers, gearboxes, bearing housings and transmissions of all types.
Available in AISI 316 stainless steel on request.
