Si 2 - Regular Flow Safety Valve
Durable safety valve for pressure relief in vapours, gases, and liquids.
Ensures stable and efficient overpressure protection.
Wide pressure range up to 40 bar for varied applications.
Available in durable materials for harsh environments.
The Si 2 Series safety valves provide reliable overpressure protection for vapours, gases, and liquids in industrial applications. Designed for set pressures up to 40 bar, these valves ensure stable and efficient pressure relief for thermal expansion, process protection, and system safety. Available in cast iron, carbon steel, and stainless steel, they deliver long-term durability in harsh environments. A cost-effective seat bushing design and optimised lift control enhance performance, while inlet sizes range from DN 25 to DN 100. Fully compliant with PED, DIN/EN, and ASME standards, the Si 2 Series offers trusted performance and safety.
