Product Details

DESCRIPTION:

As an automatic valve, API 602 standard reduced port flanged forged steel piston type lift check valve automatically opens or closes the valve flap by means of the flow of the medium itself to prevent backflow of the medium, prevent the pump and drive motor from reversing, and the leaking of the container media. It can also be used on lines where the pressure can rise to an auxiliary system that exceeds the system pressure. There are five main types to choose from: API 602 check valve, forged steel check valve, high pressure check valve, pressure seal cover check valve, socket weld lift check valve, which are widely used in pipelines of various working conditions such as petroleum, chemical, pharmaceutical, and electric power industries.
