The Safety Valve is widely used in high-pressure systems, including steam, gas, oil pipelines, and other industrial applications. It is designed to automatically open and release excess pressure, protecting vessels, pipelines, and equipment from overpressure damage. It features reliable, stable performance with a simple and durable structure.

Valve Warranty: 2 years, unconditional replacement for quality issues.

APPLICATION:

The A42F safety valve is suitable for use on equipment or pipelines carrying liquefied petroleum gas or similar non-corrosive media at operating temperatures ranging from -40°C to 80°C. The AH42F safety return valve is suitable for liquid phase return pipelines at the outlet of liquefied petroleum gas station tanks and pumps. When the pressure inside the equipment or pipeline exceeds the allowable value, the valve automatically opens and fully discharges the pressure. When the pressure drops to the specified value, the valve automatically closes, ensuring the safe operation of the equipment and pipelines.
