ASTM A105 Needle Valve

An ASTM A105 needle valve is a compact, high-pressure instrument isolation and fine-throttling valve forged from premium normalized carbon steel to deliver precise fluid regulation. The valve uses a finely threaded stem to drive a tapered, needle-like plug into a precision-machined internal orifice, enabling highly accurate flow calibration and uniform pressure reduction. Forged under the ASTM A105 standard, the robust body shell provides exceptional pressure containment, impact strength, and resistance to heavy structural vibrations. These rugged instrument valves are primary specifications for oilfield gauge lines, hydraulic control panels, refinery sampling skids, and high-pressure test manifolds. Instrument array contractors and hydraulic systems engineers can maximize calibration accuracy and secure high-pressure safety margins by importing certified ASTM A105 needle valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
