The Direct Acting Relief Valve has the function of protect the hydraulic system form malfunctioning or breaking due to too high pressure level present into the circuit.
DN15 Direct Acting Poppet Type Cartridge Relief Valve
JRD15-01
PRODUCT INTRODUCTION：
The Direct Acting Relief Valve has the function of protect the hydraulic system form malfunctioning or breaking due to too high pressure level present into the circuit.Thanks to the screw regulator is possible to set the opening pressure for the valve. Many pressure ranges are available for opening pressure up to 350 bar. Maximum working pressure for JRD15-01 Direct Acting Relief Valve is 350 bar, while it is recommended a working flow up to 60 lpm.
OPERATION：
The JRD15-01 Direct Acting Relief Valve is a direct acting cartridge valve. A poppet placed present into the valve open the flow through the cartridge when the pressure into the system reaches the setting rate.
FEATURES：
The regulator ensures that the spring will not be compacted.
The valve core and valve sleeve are hard to handle and durable.
Fast response to pressure change.
Industrial conventional valve hole.
Seat valve structure: uses cone valve core, good sealing performance and small leakage.

Performance Advantages：
Precise pressure control: can accurately limit the system pressure to the setting value, with high pressure regulation accuracy, ensuring stable operation of the hydraulic system.
Fast response speed: the direct-acting structure enables the valve core to quickly open the overflow when the system pressure reaches the setting value, protecting the system from overpressure damage in time.
High working reliability: using high-quality materials and advanced manufacturing technology, the average trouble-free working time is long, and it has high stability and durability.
Application Areas：
This series of relief valves are suitable for various industrial hydraulic systems, such as hydraulic systems of machine tools, injection molding machines, die-casting machines and other equipment. They are used to realize system overload protection, constant pressure relief and voltage stabilization functions to ensure the safe and stable operation of the hydraulic system.
