DB/DBW Relief Valve PDF

DB adjustable pressure relief valve is designed for the hydraulic units which require more hydraulic fluid flow rate as it reaches the flow rate of nearly 450L/min. DB pressure relief valve is manufactured with three individual separated parts to adjust system hydraulic pressure in machine. The solenoid valve mounted above of the base can be selected or not for option as per the different function machines and systems requirement.

Finotek manufactures the DB series adjustable pressure relief valve with three individual separated parts, direct adjusting valve (mounted on the top), main valve base(mounted on the middle position) and suplate (the bottom plate)as 20 size bottom.
