Overview: Lift check valve

2、 Detailed information

Product Overview

The lift check valve automatically opens and closes the valve disc by relying on the flow of the medium itself. Its main function is to prevent medium backflow and prevent the pump and driving motor from reversing. It has the characteristics of small size, simple structure, reliable operation, convenient maintenance, and rapid response, and is widely used as a device to prevent medium reflux in industrial pipelines.

Design and inspection can comply with standards such as API 6D, BS 1868, GB/T 12235, API 598, GB/T 26480, etc. Fire safety design meets API 6FA requirements, and NACE anti-corrosion and acid resistance are optional.

main features 

① Simple structure, reliable operation, and convenient maintenance

② The spring thrust enables the valve disc to handle closure even without medium pressure

③ High performance springs enable valves to easily achieve low-pressure sealing and opening

④ The sealing surface is welded with hard alloy, which is wear-resistant, high-temperature resistant, with good scratch resistance and long service life
