Product Formation
This is an industrial-grade brass automatic pressure relief valve (integrated with pressure/temperature sensing interface), a critical safety protection device for pipeline systems. Its main body is machined from brass material, integrating a pressure relief valve core, multi-port pipeline connection structure, and a sensing component (matched with a metal corrugated hose). It can real-time monitor pipeline pressure (or temperature); when the system pressure exceeds the set value, it automatically opens to release pressure, preventing damage to pipelines and equipment due to overpressure. It is suitable for the safety and pressure stabilization needs of various fluid pipelines.
KEY WORDS：Brass automatic pressure relief valve、Industrial pipeline safety relief valve、Pressure relief valve with sensor、Brass safety valve for fluid system、Automatic pressure release valve for HVAC、Pipeline overpressure protection valve、Brass multi-port relief valve、Corrosion-resistant pressure relief valve、Hydraulic system pressure safety valve、Threaded connection relief valve

Product Features
- Corrosion Resistance & Durability: The main body is made of H59 brass, featuring excellent corrosion resistance and aging resistance, compatible with multiple media such as water and oil.
- Automatic Safety Pressure Relief: Built-in precise pressure relief valve core; it automatically opens to discharge pressure when overpressure occurs, and closes automatically after pressure returns to normal.
- Integrated Sensing Interface: Equipped with a sensing component connected by a metal corrugated hose, supporting pressure/temperature signal transmission for convenient system monitoring.
- Multi-Port Design: Multi-directional threaded interfaces adapt to pipeline connections in different directions, offering high installation flexibility.
- Reliable Sealing: Adopts a precision sealing structure, ensuring no leakage during pressure relief and guaranteeing system operation stability.
