Application Specification and Scope of API Internal Thread American Standard Needle Valves
date:2024-05-20 10:11
API internal threaded American standard needle valves have the advantages of easy installation and disassembly, tight connection, favorable fire prevention, explosion-proof and high pressure resistance, and good sealing performance. Internal threaded needle valves are an advanced connection method in power plants, refining, chemical equipment, and instrument measurement pipelines. The needle shaped globe valve has good sealing performance and long service life. Even if the sealing surface is damaged, only vulnerable parts need to be replaced to continue use. During installation, the flow direction of the medium should be consistent with the direction of the arrow on the valve body.
