Fire Safe Ball Valve Design

The delicate seats were all burnt the valve was still fixed by the exact valve ball body.

Fire safe ball valve design.

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. Both floating trunnion mounted fires safe ball valves. Multiple stem sealing ensures high degree of sealing. Floating trunnion mounted j d controls mfg.

Higher size ball valves are designed with stem bearing to absorb radial loading on the stem. There is a big risk when accepting the low level fire safe design especially when no tests have been done at all. Both floating trunnion mounted fires safe ball valves. Floating trunnion mounted j d controls mfg.

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 design ball valves fire safe valves are designed to prevent the fire from the fuel valve if gets damaged or leaked. This will keep the harm as low as would be prudent. Floating ball valve has been approved and should also qualify a trunnion ball valve.

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. 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. We will talk about the ball valve fire safe design from perspectives of internal leakage prevention and external leakage prevention. Fire safe ball valve fire safe design ball valve j d controls manufacturing fire safe ball valve as per api 607 standard in full reduced port with antistatic device blowout proof stem with various choice of operation.

Fire safe valves are spring loaded can stop the fire flow automatically and reduces the chance of leakages. Controlling the flow of combustibles these spring loaded valves said to be very effective against any damage. Fire safe and low emission approved ball valves modentic s flanged ball valves provide the exceptional performance to serve the most critical industrial environment. 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.

The first method to achieve a fire safe design by using a fire proof component usually is referring as an inherently fire safe valve. Anti static devices are built in the valve stem to ensure electrical continuity between ball stem and body. Fire safe and low emission approval are also equipped. Fire safe valve was planned when the plant is under fire.

160 was endorsed with split body flanged pedal to the metal configuration belleville washer and graphite gasket stem pressing. Australian pipeline valve apv api6d trunnion mounted ball valves include features such as.
