1.Performance Parameters and Technical Characteristics

The JKA-N5000A spring-loaded reset safety valve provides protection for the mud pump and mud manifold, ensuring safer operation of the drilling rig during the drilling process; Replace the shear type safety valve and achieve precise control of mud pump pressure through spring adjustment. Prevent underground accidents during pump shutdown.

The JKA-N5000A spring-loaded reset safety valve can be connected with LP thread, FMC Weco union or API 6A standard 6B type 3-1/8 “(34.5MPa) flange, and the rated pressure can be flexibly set from 1500-5000PSI (10-34.5MPa).

JKA-N5000A spring type reset safety valve adopts an integral piston structure, with a simple and beautiful appearance, and easy replacement of vulnerable parts; Enable sensitivity and achieve manual reset without stopping the pump after pressure relief; The pressurized fluid adopts built-in dual protection to prevent high-pressure fluid from overflowing and causing harm to other equipment and personnel in the event of seal failure.

JKA-N5000A spring type safety valve, with a maximum working pressure of 5000PSI (34.5Mpa), belongs to high pressure the valve and its key components are made of high-strength materials, and the design, manufacturing, and testing comply with relevant API specifications, resulting in higher safety performance.

JKA-N5000A spring-loaded reset safety valve has unparalleled advantages over other competitors in the industry and can be interchanged with similar foreign products as a whole.
