Yibengfa J41H-16C Straight-Through Globe Valve: Dimensions and Technical Parameters
The "Yibengfa" name operates as a valve industry platform rather than a single manufacturing brand, but the technical data below reflects the standard J41H-16C specification shared across reputable Chinese valve makers and is directly applicable for selection and procurement.The main globe valve product names of China globe Valve Network include:QJ-6 Pneumatic Angle External Thread Pipeline Globe Valve,QJ-7 Pneumatic External Thread Pipeline Globe Valve,Self-sealing Straight-through Globe Valve,Square Flange Ammonia Globe Valve,UJ41H Flange Straight-through Plunger Globe Valve,Vacuum Isolated Straight-through Globe Valve,Y-type Jacket Insulation Globe Valve,Y-type Butt Welded Globe Valve,Y-type Rubber-lined,Fluorine-lined Globe Valve.
technical Parameters
The J41H-16C carries a nominal pressure rating of PN16 (1.6 MPa). The applicable temperature is up to 425 degrees Celsius, with media including water, steam, and oil products. The valve body and bonnet are constructed from WCB cast carbon steel. The stem is made from chrome stainless steel (typically 2Cr13), and the disc sealing surface is hardfaced with iron-based alloy. The packing consists of asbestos graphite, flexible graphite, or PTFE. Design and manufacturing follow GB/T 12235, with structural length per GB/T 12221 and flange connection per JB/T 79. Testing and inspection follow JB/T 9002.
Dimensions
Dimensions are given in millimeters, with L as face-to-face length, D as flange outer diameter, D1 as bolt circle diameter, D2 as gasket diameter, b as flange thickness, z as number of bolt holes, ød as bolt hole diameter, H as valve height, and D0 as handwheel diameter.
