How it works:<\/strong><\/h5>\n

The safety valve works by means of a mechanism that keeps the valve closed until the pressure in the system reaches the preset limit value (in this case, 17,65 bar<\/strong>). When this pressure is exceeded, the valve opens automatically, allowing the pressurised fluid or gas to be released, relieving the pressure in the system. Once the pressure has returned to a safe level, the valve closes again, restoring normal operation.<\/p>\n

Advantages:<\/strong><\/h5>\n
    \n
  • Overpressure protection<\/strong>: Prevents serious system failures and accidents due to unexpected pressure increases.<\/li>\n
  • Automatic adjustment<\/strong>: The valve closes automatically after relieving excessive pressure, which allows the system to continue operating without manual intervention.<\/li>\n
  • Durability and reliability<\/strong>: The valve is made from resistant materials, guaranteeing a long service life, even in demanding industrial environments.<\/li>\n
  • Compliance with safety standards<\/strong>: Safety valves are essential for complying with safety regulations in pressurised installations<\/li>\n<\/ul>\n

    This safety valve is essential for protecting systems under pressure, ensuring that operation is safe and efficient by preventing failures due to excess pressure.<\/p>\n
