Safety Check Valve
Product Size: NPS 2 "~24", DN50~600
Pressure rating: CL150~2500, PN16~420
Design standards: ASME B16.34, GB/T 12224
Installed at the wellhead or in oil and gas pipelines, it is used to automatically close the valve in case of sudden pressure increase or decrease in the pipeline, achieving the function of protecting pipeline equipment and also meeting bidirectional flow requirements
The working principle is to mechanically unlock the deadlock, which is a driving device used to reduce or increase pipeline pressure.
