DB/DBW Relief Valve PDF

DBW series of high pressure relief valve has four adjustable types: handle knob, adjustable bolts with protected cap, lockable and non-lockable rotary with scale for option. There are five presetting adjustable pressure: 5Mpa, 10Mpa, 20Mpa, 31.5Mpa, 350Mpa.

DBW Hydraulic pressure relief valve uses for relieving the hydraulic pressure when the pressure is rising more than the presetting pressure of the valve, this function is keeping the system pressure in the normal working operation. There are four control types of the valve, such as internal supply and leakage, internal supply and external leakage, external supply and internal leakage or external supply and leakage. Please refer the valve symbol before order.

Finotek DBW 5x series of hydraulic pressure relief valves are for high pressure system, the max. operation pressure is 31.5Mpa, the 5x series is more stable working operation in different hydraulic units.
