The Reliance RWC PREL355030 is a dedicated replacement pressure relief valve (PRV) cartridge designed specifically for the Reliance MK3 1-Piece Multibloc Inlet Control Valve Group. When an unvented cylinder's control manifold continuously drips or fails to hold pressure due to a worn or debris-damaged seating, this drop-in replacement allows heating engineers to quickly restore safety parameters without the need to cut out and replace the entire brass manifold.
