What is a needle valve?
Needle valves with knobs or ‘T’ handles are usually multi-turn from closed to full open and as such are used for either throttling (blunt needle) or metering (sharp needle). Rated for hydraulic pressures in steel, brass and stainless steel models, they are typically rated from 3000 to as high as 10000 PSI. They generally have a specified flow coefficient (Cv) to indicate how much resistance to flow they provide due to a reduced orifice size and needle interference.
