Low-Temp API Pilot-Operated Relief Valve: Rigorous Testing Ensures Safety in Extreme Cold Conditions!​

Struggling to find a reliable pressure relief valve that performs flawlessly in extreme low-temperature environments? Our pilot-operated relief valve for cryogenic service—designed and manufactured in accordance with API 526 and API 527 standards—has passed ultra-stringent testing, delivering proven performance you can trust to protect your industrial systems!​

Core Testing: Proving Reliability in Extreme Environments​
Focused on achieving a set pressure of 8.0MPa, this test subjected the valve to an extreme low temperature of -190℃, conducting comprehensive performance verification:​
In-depth valve body chemical reaction testing: Guarantees stable valve material performance under ultra-low temperatures, eliminating risks of brittleness and corrosion while ensuring long-term operational safety;​
Strict flange connection inspection: Checks sealing performance and structural stability to prevent leakage risks caused by thermal expansion and contraction in cold conditions;​
Meticulous seal qualification verification: Validates the elasticity and sealing of seal components at extreme low temperatures, ensuring precise valve opening/closing and zero leakage.​

Professional Test Setup: Simulating Real-World Extreme Work Conditions​
To replicate real cryogenic application scenarios, the test used -196℃ liquid nitrogen as the gas source, paired with the valve of 6Q8 600LB specification. This setup fully aligns with the harsh high-pressure, low-temperature demands of industrial fields, making the test results more referenceable and applicable to actual working conditions.​
