Method of operation Hitma Safety Valves

What spring safety do you need for your process? Ultimately, this is the part that protects human lives and working environments, which makes the decision all the more complicated. Hitma will be happy to help you make the right choice.

What is a safety valve?
The primary function of safety devices such as spring safety valves, also known as safety valves, as described above, is to protect human life and working environments. When pressure is too high in a process, if the upward force of the medium exceeds the downward force of the spring, the valve will open and blow off. When the pressure returns to its normal value, the valve will close again

Did you know that safety relief valves have been used since 1600? And in much the same form as today. The first spring relief valve was used in a steam digester and was invented by the German Glauber. Frenchman Papin further improved the technique.

Codes and applications
Because spring fuses play a major role in safety, the rules of design and sizing are strict. The following codes are used worldwide for this purpose:

  • ASME (American Society of Mechanical Engineers)
  • API (American Petroleum Institute)
  • DIN (German Standards Institute)

Safety valves are most commonly used on boilers, boilers and process plants in the petrochemical industry, oil and gas industry and power plants. The most common scenarios in which spring safety valves are used are blocked discharge, control valve failure, fire case and thermal expansion.

Types of spring fuses
There are different types of spring fuses in circulation:

  • Conventional
  • Balanced bellows
  • Pneumatically controlled safety (CSPRS: Controlled Safety Pressure Relief Systems)
  • Pilot operated

All types comply with PED 2014/68/EU. This is new pressure equipment directive for all member states of the European Union. We can also supply spring safety valves under API 520, ASME VIII, ASME I and DIN AD brand sheet 2000 standards. We can supply valves with CE, UV or V marking.
