In the steam generator and boiler industry, safety relief valves are indispensable for maintaining system integrity. Our models—G20/L (PN 60), G25/L (PN 60), and G32/L (PN 40)—are available in DN15 to DN65 flanged versions and manufactured from SS316L stainless steel to withstand high-pressure and high-temperature environments.
These valves are directly mounted on steam generators to control internal pressure. When the pressure exceeds the preset limit, the safety valve opens to discharge excess steam, protecting the system from damage. Constant exposure to superheated steam demands materials that can resist thermal stress and aggressive conditions.
High Temperature Challenges:
- • Thermal expansion: Steam heat causes material deformation and tolerance shifts.
- • Material resistance: Prolonged exposure to heat can weaken components.
- • Seal wear: Heat degrades seals and sealing surfaces over time.
- • Spring setpoint drift: Heat can change the tension in set springs, affecting opening pressure.
- • Erosion and corrosion: Superheated and impure steam can degrade internal surfaces.
Our safety valves are calibrated directly on steam generators to replicate actual working conditions, ensuring precise operation under real-world stress. This is essential for reliable function and compliance with safety standards.
Rotating Flange Design for Easy Installation:
Steam systems often face alignment challenges. Our valves come with a rotating collar flange at the inlet. This allows precise positioning of the valve outlet with system piping, reducing installation time, improving fit, and enhancing operational reliability.
Maintenance Considerations:
Steam generators operate continuously, and valve maintenance usually requires system shutdown. This leads to production downtime and high maintenance cost. Our valves are built for durability to minimize maintenance frequency, ensuring long-term performance in continuous operations.
