Lug Check Valve
Nominal Diameter: 2" ~ 24"
Nominal Pressure: 150 ~ 2500 lb
Mediums: Water, sewage, oil, gas, chemicals
Temperature Range: ≤ 425°C
Lug Check Valve
The Lug Check Valve is designed to prevent backflow in piping systems, ensuring safe and efficient fluid transportation. Featuring a lug-style body design, the valve can be installed between flanges and allows for easy maintenance of downstream equipment without disturbing the entire pipeline. It offers reliable sealing performance, low pressure drop, and long service life across a wide range of industrial applications.
