DBW20 DBW10 DB20 DB10 Pilot Solenoid Overflow Valve
DBW20, DBW10, DB20, DB10 pilot solenoid overflow valves are commonly used in hydraulic systems. The following is a detailed introduction from the aspects of product characteristics, technical parameters, application scenarios, working principles and selection suggestions:
1. Product Features
The pilot structure controls the opening and closing of the main valve through the pilot valve to achieve pressure regulation, and has the advantages of high sensitivity and stable pressure.
It can be remotely controlled to enable the opening or closing of the overflow valve through the solenoid power-off.
Various specifications and models DBW20/DBW10: Indicates pilot solenoid relief valves with nominal diameters of 20mm and 10mm.
DB20/DB10: May be similar products of different brands or series, with similar functions to DBW series.
The pressure regulation range is wide and the overflow pressure can be adjusted according to the system needs, which is suitable for different working conditions.
Safety protection function When the system pressure exceeds the set value, the relief valve will automatically open to protect the hydraulic system from overload damage.
2. Technical parameters (taking common models as examples)
Parameter DBW20DBW10
Nominal diameter 20mm 10mm
Pressure level 31.5MPa 31.5MPa
Flow range 160-400L/min (depending on model) 40-160L/min (depending on model)
Control method electromagnetic control electromagnetic control
Installation form Plate type mounting Plate type installation
Applicable medium hydraulic oil hydraulic oil
III. Application scenarios
Hydraulic systems for construction machinery excavators, cranes, road rollers and other equipment, used to control pressure and protect systems.
Industrial equipment injection molding machines, die casting machines, machine tools, etc. to achieve pressure stability and system protection.
Agricultural machinery tractors, harvesters, etc. control the pressure and action of the hydraulic suspension system.
Hydraulic systems such as anchoring machines and servoes in ship and marine engineering ensure the safe operation of equipment.
4. Working principle
Pilot valve control When the system pressure reaches the pilot valve set value, the pilot valve is opened to control oil flow into the upper chamber of the main valve core.
The pressure of the upper chamber of the main valve opening and closing of the main valve core increases, overcomes the spring force, the main valve opens, oil overflows back to the oil tank, and the system pressure drops.
The electromagnetic control solenoid is powered on or off, and the opening and closing of the pilot valve is controlled, thereby controlling the operation of the main valve.
5. Product Advantages
The pressure stabilization pilot structure makes pressure adjustment more sensitive and stable.
Remote control can achieve remote operation through electromagnetic control, which facilitates automatic control.
Safe and reliable When the system pressure is too high, it will automatically overflow to protect the system safety.
It has a wide range of application and is suitable for a variety of hydraulic systems to meet the needs of different working conditions.
