DESCRIPTION

Our Closed Spring Loaded Low Lift Type High Pressure Safety Valves are utilized for corrosive equipment and pipelines. A41Y-160/320 kinds are utilized for equipment and pipelines that function below 200°C. A41Y-160P/320P and A41Y-160R/320R are utilized for corrosive gas and liquid equipment and pipelines below 200°C. Add pressure protection. A42Y-C is utilized for air, petroleum gas, liquid, and other low-temperature equipment and pipelines. A42Y-P and A42Y-R are utilized for corrosive equipment and pipelines. What’s below 200°C? A48Y is used in steam and air equipment and pipes up to 350. Use pressure-protection equipment. A48Y type is used for steam and air equipment and pipelines with temperatures below 350°C. A44Y type is utilized for air and petroleum gas operating temperatures less than 300°C equipment and pipelines. Add pressure protection devices.

Benefits:

It uses a pressure self-sealing design and is joined at both ends by welding.
To compensate for the difference in pressure between the intake and exit, it uses an electronic bypass valve.
The method for shutting it uses a parallel pair of flashboards. To avoid dangerous strain during opening and shutting, the valve is sealed not by a wedge but by medium pressure.
The sealing face has been built up using a strong alloy based on cobalt, which gives it great temperature resistance, corrosion resistance, abrasion resistance, and long service life.
Valve stem surfaces that have been treated against corrosion and nitrogenization have improved corrosion resistance, abrasion resistance, and stuffing box sealing.
