A seal for a poppet valve of an integrated pressure management apparatus, a valve system using the poppet valve seal, and a method of cleaning debris off of a poppet valve. The poppet valve is movable between an open position permitting fluid flow through an aperture in a housing and a closed position preventing fluid flow through the aperture. The seal includes an annular body having a first sealing surface fixed to the housing and a second sealing surface confronting the poppet valve. An annular lip projects obliquely from the seal is resiliently deformed by the poppet valve at the closed position, thereby cleaning debris off the sealing surface of the poppet valve.
