Pressure Relief Valves DBD directly-operated Pressure Relief Valves DBD Description For line installation, the housing has two connections with Whitworth pipe threads. Without housing, the valve cartridge can alternatively be screwed into the specified bore contour in any body desired. The pressure relief valve DBD is a directly-operated poppet valve for installation in the pipelines or as a clamp-in valve. The valve is used to safeguard the pressure of hydraulic systems up to pmax = 400 bar. Valve cone 2 is pressed by compressed spring 5 into valve seat 3, thus blocking pump connection P from...
