J14W Needle Valve
Core Function & Application Positioning
With an angular internal thread design, this needle valve with gauge can compress the pipeline layout angle to 90° while achieving precise flow adjustment, greatly saving installation space. The needle valve with gauge is suitable for medium control in space-constrained petrochemical sampling pipelines and micro-hydraulic equipment, especially for flow control in dense pipelines inside cabinets, with an adjustment range of 0-50L/h.
Material & Craftsmanship
The valve body is integrally forged with 304/316 stainless steel. The valve seat adopts an integrated injection molding sealing process, and the sealing surface is mirror-polished with a roughness of Ra≤0.8μm, which can withstand long-term scouring of weakly corrosive media. The valve body is annealed after forging to eliminate internal stress, ensuring the durability of the needle valve with gauge.
Specification Advantages
All models cover various thread specifications such as M10×1, G1/4, and NPT1/8, support customization of non-standard special-shaped thread interfaces, can meet the docking needs of instruments of different brands such as Siemens and Yokogawa, and provide complete pipeline connection solutions.
Summary
The angular structure of this needle valve with gauge is perfectly suitable for compact pipeline scenarios. The mirror sealing surface ensures zero leakage, and the customized interface can match various imported instruments. Its annealed valve body can avoid deformation caused by temperature differences in working conditions, making it an ideal component for medium control in narrow spaces.
