Safety protection: This brass pressure relief valve prevents overpressure in closed water systems such as boilers by opening when liquid pressure exceeds the preset limit, providing reliable safety for home plumbing. Adjustable performance: It features 1/2inch threads and an adjustable opening pressure of ≤0.1 MPa, allowing precise control for various applications and helping maintain a consistent flow direction while avoiding backflow in water systems. Lasting construction: Made from brass with a silver finish, this valve withstands temperatures up to 100°C and offers longlasting operation, resisting erosion and wear in demanding environments. Efficient flow management: With a flow rate of 0.28 L/s under 0.03 metersPa water pressure and minimal leakage (relief pressure >0.8 MPa stops external leakage), it helps maintain system integrity and reduce water waste. Compatibility and fit: Designed with 1/2inch threads to align with common pipe fittings for straightforward installation and reliable operation. Practical applications: Suitable for residential boilers and closed heating circuits, domestic hot water heaters or storage tanks in compact installations, and closedloop systems such as solar water heating or small commercial equipment requiring dependable pressure relief.
