LYV® Piston Lift Check Valve Introduction
Piston Lift Check Valve requirements of each customer, so the quality of our lift check valve has been well received by many customers and enjoyed a good reputation in many countries. LYV® lift check valve have characteristic design & practical performance & competitive price, for more information on thelift check valve , please feel free to contact us. LYV® Piston Lift Check Valve is a kind of closed valve disc used to prevent media backflow of the valve of the automatic valve, its main role is to prevent media backflow, prevent the pump and drive motor reversal, and used as a vessel media discharge. Stainless steel lifting check valve controls the one-way flow of media in the pipeline to prevent media backflow. Pressure PN16~PN160,150LB-2500LB, suitable for pressure 1.6~25MPa/2.0-42.0MPa working temperature -29~+550℃ of petroleum, chemical industry, pharmaceutical, chemical fertilizer, power industry and other working conditions of the pipeline, suitable for the medium for water, oil, steam, acid medium, etc. Lifting check valve is selected for nominal pressure PN1.6 ~ 160MPa/2.0-42.0MPa working temperature -29 ~ 550℃ petroleum, chemical, thermal power stations and other working conditions of the pipeline. Applicable medium: water, oil, steam, etc
