Fire Safe Ball Valve Design

Fire safe design for ball valve is a design that the material and the structure of ball valve can pass a fire test with limited leakage to the atmosphere and downstream after fire exposure.

Fire safe ball valve design.

Modentic s flanged ball valve line includes one piece two piece three piece and wafer type construction. Multiple stem sealing ensures high degree of sealing. Floating trunnion mounted j d controls mfg. Thus providing greater safety while handling volatile media.

Both floating trunnion mounted fires safe ball valves. Fire safe and low emission approved ball valves modentic s flanged ball valves provide the exceptional performance to serve the most critical industrial environment. There is a big risk when accepting the low level fire safe design especially when no tests have been done at all. We will talk about the ball valve fire safe design from perspectives of internal leakage prevention and external leakage prevention.

160 was endorsed with split body flanged pedal to the metal configuration belleville washer and graphite gasket stem pressing. Higher size ball valves are designed with stem bearing to absorb radial loading on the stem. Fire safe and low emission approval are also equipped. Fire safe design ball valves fire safe valves are designed to prevent the fire from the fuel valve if gets damaged or leaked.

Anti static devices are built in the valve stem to ensure electrical continuity between ball stem and body. In the floating ball design where sealing takes place by allowing the ball under pressure to move towards the downstream seat to effect tight seal. Usually this type of valve is a metal seated valve by using a graphite seat insert in ball valve or butterfly valve and graphite stem packing. Floating trunnion mounted j d controls mfg.

Australian pipeline valve apv api6d trunnion mounted ball valves include features such as. Floating ball valve has been approved and should also qualify a trunnion ball valve. This will keep the harm as low as would be prudent. Nace specification api6fa api607 7th edition iso 10497 2 firesafe certified design iso 15848 1 2015 fugitive emission certified design esdv service suitability and b b db b capability.

Fire safe valves are spring loaded can stop the fire flow automatically and reduces the chance of leakages. The delicate seats were all burnt the valve was still fixed by the exact valve ball body. The valve design has not been tested not even a similar one or there are large deviations in design in comparison to an approved one e g. Controlling the flow of combustibles these spring loaded valves said to be very effective against any damage.

Both floating trunnion mounted fires safe ball valves. Fire safe valve was planned when the plant is under fire.
