a housing;
media passaging extending through the housing, the media passaging including a media inlet for receiving the media from a supply of media and a media outlet for dispensing media from the metering valve into the pressurized fluid;
a valve seat defining a portion of the media passaging, the valve seat including a rib; and
a plunger movable in the housing and including a plunger head, the plunger movable between a closed position in which the plunger head sealingly contacts the rib of the valve seat to prevent flow of media through the media passaging and an open position in which the plunger head is spaced apart from the rib of the valve seat to permit media to flow through the valve passaging, the plunger being movable distally to move the plunger head toward the valve seat to the closed position, the plunger head including a first sealing surface configured to press distally against the rib of the valve seat in the closed position for sealingly contacting the rib of the valve seat in the closed position;
