poppet relief valve

The DBD series of direct spring pressure relief valves are ideal for inline mounting. They compensate for the limits of hydraulic system operating pressures. The hexagon socket grub screw gives the operator the option to modify the operating pressure. Their spring loaded poppets secure their valve seats. Then, if the set spring force is overpowered by the line pressure, the poppet makes way for the free flow of pressure to drain the chamber. Moreover, these inline pressure relief valves are available as cartridges.
