DN10 Directly Cartridge Relief Valve，Used as a pressure limiting device to protect hydraulic circuits.
DN10 Direct Acting Poppet Type Cartridge Relief Valve
JRD10-03
OPERATION：
Valve core closed state: When the oil inlet pressure is lower than the set pressure of the relief valve, the valve core is tightly attached to the valve seat under the action of the pressure regulating spring, and the oil inlet and oil outlet are blocked. At this time, the oil inlet pressure mainly depends on the external load.
Valve core open overflow: When the oil force is greater than the spring force, the valve core opens and the oil flows back to the oil tank from the overflow port. As the opening of the relief valve increases, the spring force also increases until it is balanced with the hydraulic force. When the relief valve begins to overflow, the pressure at its oil inlet is basically stable at the set value, which plays the role of overflow pressure stabilization.
FEATURES：
The regulator ensures that the spring will not be compacted.
Optional optional pressure range up to 230bar(3335psi).
The valve core and valve sleeve are hard to handle and durable.
High sensitivity, able to respond quickly to changes in system pressure
Industrial conventional valve hole.

Application Scenario：
Small hydraulic systems: such as small machine tool hydraulic systems, hydraulic tools, etc., these systems have low pressure and flow requirements, and Directly Cartridge Relief Valve can meet their pressure control needs.
Safety valve: In some systems, Directly Cartridge Relief Valve can be used as safety valves. When the system pressure exceeds the set value, the overflow is quickly opened to prevent the system pressure from being too high, causing equipment damage or safety accidents.
Low-precision pressure control occasions: For some occasions that do not require high pressure control accuracy, such as simple hydraulic lifting platforms, Directly Cartridge Relief Valve can achieve basic pressure stability control.
