Frequently Asked Questions

Q: What does "4 Points" mean for this stainless steel needle valve?

A: "4 Points" refers to the thread size designation commonly used in Chinese plumbing standards, equivalent to a 1/2-inch BSP (British Standard Pipe) thread. This is the external male thread size of the valve's connection port, making it compatible with standard 1/2" BSP fittings and pipelines.

Q: What is the difference between the J23W and J24W needle valve models?

A: The J23W and J24W designations refer to variations in design configuration within the same high-pressure needle globe valve series. The 160P and 64P suffixes indicate the pressure rating class (PN160 and PN64 respectively). Both feature 304 stainless steel construction, welded casting, and external threaded connections, but may differ in pressure tolerance thresholds and internal configurations suited to specific system requirements.

Q: Is this needle valve suitable for use with corrosive fluids or chemicals?

A: The 304 stainless steel construction offers strong resistance to many common corrosive substances, including water, mild acids, and general industrial fluids. However, for highly aggressive chemicals or specific media compatibility, always verify the chemical resistance chart for 304 SS before installation to ensure safe and reliable operation.

Q: How do I install this high-pressure threaded needle valve?

A: This valve features an external male thread (4-point / 1/2" BSP) connection, allowing it to be threaded directly into compatible female-threaded fittings or pipe ends. Use appropriate thread sealant tape (PTFE tape) or thread compound to ensure a leak-free seal. The hexagon head allows for easy tightening using a standard wrench. Always ensure the system is depressurized before installation or removal.
