In recent months, A28H-series spring full-lift safety valves have become one of the most frequently requested valve products at SHANGHAI WUYUE PUMP VALVE GROUP CO., LTD. Customers from various industries—steam systems, compressed-air stations, chemical processing lines and general utility pipelines—have been actively inquiring about this robust and highly adaptable model. To help more clients understand this product clearly, we present this detailed overview of the A28H and A28Y threaded safety valve series.

1. Product Overview: Designed for Stable Performance and Easy Integration

The A28H safety valve is a widely used threaded-connection spring full-lift model designed to provide rapid pressure relief and stable protection in overpressure conditions. With a nominal pressure range from 1.0 MPa to 6.4 MPa and sizes from DN15 to DN80, it can be easily installed on small, medium or large pipeline systems.

Depending on the working medium, two sealing structures are available:

A28H: Standard sealing for neutral media

A28Y: Stainless-steel or special alloy sealing for corrosive media

This flexibility allows engineers to match the exact valve type to the actual process requirements, ensuring a safe, durable and efficient operating environment.

2. Application Conditions and Material Options

The A28H model is suitable for equipment and pipelines with a working temperature ≤ 200°C, including:

Air

Steam

Water

Nitrogen

Hydrogen mixtures

For systems involving corrosive media, A28Y-P or A28Y-10R8 / 16R8 / 25R8 / 40R8 models are recommended. These versions use corrosion-resistant materials to ensure long-term stability even under demanding chemical conditions.

All series are designed as overpressure protection devices, protecting pipelines, vessels, generators and utility systems from the risks of sudden pressure increase. Every valve undergoes strict factory testing—spring force, lift height, body leakage and set pressure accuracy—guaranteeing that each product meets GB / API / international quality standards.
