How do single spring valves work?
A single spring safety valve uses an adjustable spring to hold the valve closed until system pressure reaches the set limit. When pressure exceeds this point, the spring compresses, allowing the valve to open and release excess pressure.
Advantages of single spring valves...
• Reliable over‑pressure protection
• Simple, proven design
• Adjustable set pressure
• Fast opening and closing action
