Product details
Pilot operated pressure relief valve uses for controlling the system pressure, keeping system pressure in a normal level in order to protect each actuator operation, especially the power actuation like hydraulic motors, hydraulics pumps.Finotek DBW series of pilot operated pressure relief valve is designed by two parts, the combination of parts of main valve as basic and pilot operated pressure direct relief valve enable to minimize valve pressure adjusting torque force more than by only a direct relief valve, its largely developing the valve characteristics of opening and closing speed. Example (Normal code):"FT-DBW 10 B 1 5X/20 EG24NZ5L " Explanation As Below:FT-DBW10B 15X/20  6EG24NZ5L   (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(1) Producer code= FT(2) W= With solenoid valveNo code= Without solenoid valve(3) Size= 10; 15; 20; 25 or 30(4) A= Normal closedB= Normal open(5) No code= Modular mountedG= Threaded mounted(6) 1= Hand wheel adjustment 2= Screw adjustment and protective cap(7) 5X= Valve series(8) 20= Settable pressure up to 20Mpa5= Settable pressure up to 5Mpa10= Settable pressure up to 10Mpa31.5= Settable pressure up to 31.5Mpa(9) No code= Internally piloted, internally drained X= Externally piloted, internally drainedY= Internally piloted, externally drainedXY= Externally piloted, externally drained(10) No code= StandardU= Min. opening pressure(11) 6E= (Wet-pin) solenoid with detachable coil(12) G24= DC voltage 24V G12= DC voltage 12V W220= AC voltage 220~230V 50/60 Hz W110= AC voltage 110V 50/60 Hz(13) N= With manual override(14) Z5L= Plug-in connection with indicator lamp(15) No code= Inch thread (Y port threaded) 2= Metric thread (Y port threaded)(16) No code = NBR seals for petroleum oilV = FPM seals for phosphate ester(17) No code = Black GalvanizationB= Blue Powder Coating
