Product Model: YFJ49H/Y
Product grade: PN6.4-32.0MPa
Product material: WCB/304/316
Product specifications: DN3-DN15
The application, working principle and technical performance of the YFJ49 type pressure gauge stop valve are the same as those of the J29 type pressure gauge stop valve, and their structures are basically the same. The only difference is the connection form. One end of this valve is connected by a weld bead while the other end is connected by a flange.
The YFJ29H pressure gauge stop valve can withstand greater pressure than other types of valves and has good sealing performance. Therefore, it is generally used for sealing gas or liquid media with small flow rates and high pressure. Needle valves are most suitable to be used in conjunction with pressure gauges. The YFJ29H pressure gauge stop valve is widely used in pipelines carrying media such as oil, gas, steam, water, nitrogen and hydrogen mixtures as an opening and closing device for pressure testing. It features a firm connection, excellent sealing performance and sewage discharge capability.
