J49H針型閥是一種小流量、高精度的閥門，主要用于調節流量和壓力。它的結構簡單，操作方便，密封性好，耐腐蝕性強，壽命長。該閥門采用針形閥芯，通過旋轉閥芯來調節流量和壓力，具有精度高、響應快、穩定性好等特點。同時，該閥門還具有防震、防爆、防火等安全保護措施，能夠滿足各種復雜的工作環境要求。

The J49H needle valve is a small flow, high precision valve that is mainly used to regulate flow and pressure. It has a simple structure, easy operation, good sealing performance, strong corrosion resistance, and long service life. The valve uses a needle-shaped valve core to adjust flow and pressure by rotating the valve core, and has the characteristics of high precision, fast response, and good stability. At the same time, the valve also has safety protection measures such as shock resistance, explosion-proof, and fire prevention, which can meet various complex working environment requirements.

該閥門的主要材料為不銹鋼、碳鋼、合金鋼等，可根據用戶的要求進行定制。其連接方式有螺紋連接、法蘭連接、對夾連接等多種形式，可適應不同的管道連接要求。該閥門的公稱壓力范圍為0.6MPa~32MPa，公稱通徑范圍為DN2~DN50，可滿足不同流量和壓力的要求。

The main materials of the valve are stainless steel, carbon steel, alloy steel, etc., which can be customized according to user requirements. Its connection methods include threaded connection, flange connection, clamp connection, and other forms, which can adapt to different pipeline connection requirements. The nominal pressure range of the valve is 0.6MPa~32MPa, and the nominal diameter range is DN2~DN50, which can meet the requirements of different flow rates and pressures.
