We used ASTM A320 Gr.L7 to connect the body and bonnet. It could extend the valve longer service life.

Using ASTM A320 Gr.L7 material for connecting valve bodies and bonnets offers several significant benefits, particularly in low-temperature and high-pressure applications. Here are the key advantages:

Low-Temperature Toughness: ASTM A320 Gr.L7 is specifically designed for low-temperature service. It maintains excellent toughness and impact resistance even at extremely low temperatures, making it ideal for cryogenic applications where materials can become brittle.

High Strength: This grade provides high tensile and yield strength, ensuring the valve can withstand high internal pressures without deformation or failure. This is crucial for maintaining the integrity of the valve in demanding environments.

Fail-Safe Design: Ensures safety in case of air supply failure.

Lower Air Consumption: More energy-efficient than double-acting actuators.

Simpler Installation: Requires only one air supply line.

Cost-Effective: Fewer components and lower maintenance costs.
