Description
Double ferrule compression-type needle valve, a subtype of globe valve, with a needle-shaped stem tip for precise flow regulation. Available in stainless steel and carbon steel body materials across a range of tube sizes. Designed for use in instrument measurement pipelines, power stations, oil refining, and chemical installations.
Selection notes
This needle valve is a compression and double ferrule pattern, supplied for double ferrule compression installation.
Sizes run NPS 1/8" to NPS 1", in 10000 psi (689 bar).
The body is offered in SS304, SS316 and A105, so the grade can be matched to the service rather than the other way round.
Stated service media include oil, gas, water and acid liquid.
It is catalogued for Water & Wastewater and Industrial Process.
Working temperature is -53°C to 649°C, by material.
