High-pressure needle valve (globe valve) 'H-99 Series'

Stainless steel 316 high-temperature and high-pressure needle valve H-99 series. Pressure resistance up to a maximum of 69 MPa. Improved reliability with three types of stem shapes.

The H-99 series is a robustly designed and constructed general-purpose needle valve (globe valve). Made of stainless steel, it is suitable for a wide range of applications and is resistant to high pressure (up to 69 MPa) and high temperatures. It is particularly useful in harsh environments, high-pressure sampling systems, high-pressure shut-off systems, and test stands. Additionally, three types of stems are available (regulating stem, V stem, and non-rotating stem). <Features> - Packing bolt specification allows for easy panel installation without disassembling the sealing part. - Options available for oxygen-free and completely oil-free environments. - Seal kits and handle kits are available for maintenance. - The surface of the stem undergoes diffusion hardening treatment, providing optimal resistance to galling, as well as wear and corrosion resistance. *For more details, please download the PDF or feel free to contact us.

Ultra-small needle valve

Adjustable flow small needle valve. Seal materials include NBR, EPDM, and FKM.

A needle valve is a valve that adjusts and controls the flow rate by varying the orifice with a built-in pin. It is useful when the exact flow rate of the system is not determined or when compensating for flow variations caused by other devices. Depending on the fluid, sealing materials can be selected from NBR, EPDM, or FKM.
