In industrial pressure systems, safety is never theoretical—it is proven in real operating environments. The A22H/Y/W/F Safety Valve, a spring-loaded full-lift threaded safety valve, is designed to respond rapidly to overpressure conditions and ensure complete discharge when needed.Shanghai WUYUE Pump Valve Group Co., Ltd.has successfully delivered customized A22 series solutions to international clients, including demanding projects in Saudi Arabia and the United States, demonstrating its engineering expertise and global manufacturing capabilities.

From Saudi Arabia: Reliable Protection in Harsh Desert Conditions

A petrochemical contractor based in Saudi Arabia approached Shanghai WUYUE with a critical challenge. Their pipeline system transported high-temperature hydrocarbon gases under fluctuating pressure, and the safety valves previously used showed signs of sealing instability due to extreme environmental conditions.

After a comprehensive analysis, WUYUE engineers recommended the A22Y Safety Valve, featuring astellite (hard alloy) sealing surface. This material selection significantly enhanced wear resistance and maintained tight sealing even under high-temperature and high-frequency operation. The threaded connection design also allowed easier on-site installation in compact pipeline layouts.

During commissioning, the A22Y valve demonstratedfast full-lift discharge performance, ensuring that pressure was released instantly once the set limit was exceeded. The client reported that the system achieved more stable pressure control and reduced downtime caused by valve maintenance. In the harsh desert climate, the durability of the A22Y configuration proved especially valuable.

From the United States: Precision and Compliance in Gas Systems

In another project, a U.S.-based industrial gas company required a series of compact threaded safety valves for a controlled gas distribution system. The application demandedhigh sealing accuracy, minimal leakage, and strict compliance with operational safety standards.

Shanghai WUYUE proposed a tailored solution using theA22F Safety Valve, equipped with asoft sealing surface (PTFE). This design ensured excellent tightness, particularly suitable for clean gas media where leakage must be minimized. Additionally, for sections of the system exposed to mildly corrosive gases, theA22W variantwith stainless steel sealing was also supplied.

Throughout installation and testing, the valves deliveredconsistent opening pressure, reliable resealing, and stable operation. The customer highlighted that the compact threaded design simplified integration into their existing system, while the material flexibility of H/Y/W/F options allowed precise matching with different pipeline sections. The project reinforced WUYUE’s capability to meet stringent international requirements.

Product Features of A22H/Y/W/F Safety Valve

TheA22H/Y/W/F Safety Valveis aspring-loaded full-lift, closed-type threaded safety valve, specifically designed for applications requiring rapid and sufficient pressure release. Compared with micro-lift valves, the A22 series provides alarger discharge capacity, making it ideal for systems where quick pressure relief is critical.

Key features include:

• Full-lift structure: Ensures maximum discharge capacity during overpressure events
• Threaded connection (BSP/NPT): Convenient installation and maintenance
• Wide material adaptabilitythrough sealing surface options:
  • H Type: Metal hard seal for general media
  • Y Type: Stellite alloy for high temperature and wear resistance
  • W Type: Stainless steel for corrosive environments
  • F Type: Soft seal (PTFE) for high-tightness gas applications
• Stable spring mechanism: Accurate pressure setting and repeatable performance

These features make the A22 series suitable for air, steam, petroleum gas, and various industrial fluids across multiple industries.
