SE - Quick Release Isolation Valve
Fast-acting SE globe valve ensures emergency cooling with high actuating force and rapid isolation.
Quick-release isolation ensures fast emergency cooling.
System-actuated force enables energy-free operation.
Compact, enclosed design withstands seismic conditions.
The SE Type Globe Valve is designed for emergency cooling, providing rapid isolation via a quick-release mechanism powered by system pressure. Using a depressurising principle, it operates without external energy. Various pilot valves, including solenoid and spring-loaded options, ensure flexibility. Available in sizes up to 11” (280mm) and Class ratings up to 1500, it handles steam and two-phase flows. Built from forged or cast carbon and stainless steel, its compact, enclosed design enhances durability and seismic resilience. This reliable, maintenance-free valve is ideal for critical safety applications where rapid and secure operation is essential.
