Yibengfa J13W-16P Internal Thread Needle Valve: Dimensions and Technical Parameters
While the specific brand “Yibengfa” (壹泵阀) appears as a valve industry platform and trading entity rather than a manufacturer of this particular model , the technical data below reflects the standard J13W-16P specification shared across reputable Chinese valve makers, which is directly applicable for selection and procurement.The main needle valve product names of China needle valve Network include:ANSI J11W/H Internal And External Thread Needle Valve,ANSI J11W/H Internal Thread Needle Valve,ANSI JG-1F/JG-2F Multi-entrance Metering Valve,CJ123 Multi-functional Pressure Gage Needle Valve,EN5-4 SS-M2F8 Internal Thread Three-valve Manifold,EN5-1 SS-M2F8 Internal Thread Two-valve Manifold,EN5-2 EF-2 Two-valve Manifold,EN5-3 WF1/2 Five-valve Manifold,EN5-5 QF-05 Meter Balanced Valve,EN5-6 QFF3 Three-valve Manifold,Electric Soft-sealed Wafer Needle Valve.
Technical Parameters
The J13W-16P carries a nominal pressure rating of PN16 (1.6 MPa). Shell test pressure is 2.4 MPa, liquid seal test pressure is 1.76 MPa, and gas seal test pressure is 0.6 MPa . The maximum working temperature is generally stated as P≤540°C for the stainless steel variant, suitable for media including water, steam, oil products, and liquefied petroleum gas .
The valve body, bonnet, stem, and disc are constructed from chrome-nickel stainless steel (铬镍不锈钢), while the packing consists of PTFE and flexible graphite . This combination provides reliable sealing and moderate corrosion resistance for non-aggressive service.

Summary
The J13W-16P internal thread needle valve offers a PN16 rating, stainless steel wetted parts, and PTFE/graphite packing for service up to 540°C in steam, water, and oil applications. Dimensions are available from DN6 through DN40 with corresponding NPT or BSP thread connections. For project procurement, confirm the specific manufacturer’s material certificates and pressure test reports, as dimensional tolerances may vary slightly between suppliers.
