DAW10 DA20 Pilot Unloading And Relief Valve Pilot Solenoid Unloading And Relief Valve
DAW10 and DAW20 pilot unloading and relief valves (pilot electromagnetic unloading and relief valves) are key components used in hydraulic systems to control pressure and realize system unloading. The following is a detailed introduction from the aspects of product characteristics, technical parameters, application scenarios, working principles, selection suggestions, etc.:
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 of DAW10: Nominal diameter is 10mm, suitable for small and medium flow hydraulic systems.
DAW20: The nominal diameter is 20mm, suitable for medium and large flow hydraulic systems.
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.
Energy-saving design When the system pressure is lower than the set value, the main valve is closed to reduce energy loss.

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.
Energy and mining hydraulic support, drilling rig and other equipment provide stable pressure control.
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.
Energy-saving and efficient When the system pressure is lower than the set value, the main valve is closed to reduce energy loss.
