900 Series DIN Spring loaded Pressure Safety Valve
 

900 Series DIN Spring loaded Pressure Safety Valve 


900 Series DIN standard Safety Valve are mainly applied to the industries such as petroleum & Natural gas, Chemistry, Electric, Metallurgy & Burning gas. DIN safety valve, pressure safety valve, safety relief valve.

900 DIN Spring loaded Pressure Safety Valve

DIN Standard Safety Valve Features: 

Safety valves were first used on steam boilers during the industrial revolution. Early boilers without them were prone to accidental Explosion.
Safety valves also evolved to protect equipment such as pressure vessel (fired or not) and heat exchangers. Safety valve term should be limited to compressible fluid application (gas, vapor, steam).

The two general types of protection encountered in industry are thermal protection and flow protection.

  

For liquid-packed vessels, thermal relief valves are generally characterized by the relatively small size of the safety valve necessary to provide protection from excess pressure caused by thermal expansion. In this case a small valve is adequate because most liquids are nearly incompressible, and so a relatively small amount of fluid discharged through the relief valve will produce a substantial reduction in pressure.

A48 Spring loaded full lift safety valve
  • A48 Spring loaded full lift safety valve 


    A48 Type Spring Loaded Full Lift Safety Valve is one in which the disc lifts sufficiently, so that the curtain area no longer influences the discharge area.
A27 Spring loaded low lift type safety valve
A48SB High temperature and high pressure safety valve

A full lift safety valve is one in which the disc lifts sufficiently, so that the curtain area no longer influences the discharge area. The discharge area, and therefore the capacity of the valve are subsequently determined by the bore area. This occurs when the disc lifts a distance of at least a quarter of the bore diameter. A full lift conventional safety valve is often the best choice for general steam applications.

 

Full lift safety valve opening height is more than one fourth times of the flow diameter. it has an advantage of discharging greatly .

 

APPLICATION:

A48 Type Spring Loaded Full Lift Safety Valve is applicable as the pressure protecting device in the equipment or pipelines for steam, air,etc.,  which the working medium is  ≤350℃.

These safety valves are used as Extra Pressure Protection Device for the equipment and pipeline of the steam, ect. The working temperature with Carbon Material Type are less than 425℃ and with WC6 Material type are less than 500℃ and WC9 Material Type are less than 550℃.
