Closed Spring Loaded Low Lift Type High Pressure Safety Valve

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.
