Application:

Sanitary stainless steel safety valve, also called pressure relief valve, is widely used to protect pipe lines and pump from break down by over pressure in food, beverage, pharmacy, brewery, wine, diary industries.

Working Principle:

• Set the valve pressure at a specific value
• Valve is normally closed by outside force
• When pipeline pressure exceeds the set value, the valve will open automatically
• Medium is discharged through safety valve
• Pipeline pressure reduces and returns to safety value
• Valve closes by itself until next cycle of excessive pressure
