Fire Safe Ball Valve Design

Both floating trunnion mounted fires safe ball valves.

Fire safe ball valve design.

Australian pipeline valve apv api6d trunnion mounted ball valves include features such as. This will keep the harm as low as would be prudent. 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. 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.

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. 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. Fire safe and low emission approved ball valves modentic s flanged ball valves provide the exceptional performance to serve the most critical industrial environment. For higher sizes and pressure ratings trunnion mounted ball valves are preferred by industry.

Floating trunnion mounted j d controls mfg. The first method to achieve a fire safe design by using a fire proof component usually is referring as an inherently fire safe valve. There is a big risk when accepting the low level fire safe design especially when no tests have been done at all. Controlling the flow of combustibles these spring loaded valves said to be very effective against any damage.

160 was endorsed with split body flanged pedal to the metal configuration belleville washer and graphite gasket stem pressing. Fire safe valves are spring loaded can stop the fire flow automatically and reduces the chance of leakages. Fire safe valve was planned when the plant is under fire. Anti static devices are built in the valve stem to ensure electrical continuity between ball stem and body.

Both floating trunnion mounted fires safe ball valves. 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. Thus providing greater safety while handling volatile media. Multiple stem sealing ensures high degree of sealing.

Floating ball valve has been approved and should also qualify a trunnion ball valve. Modentic s flanged ball valve line includes one piece two piece three piece and wafer type construction. 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 and low emission approval are also equipped.

The delicate seats were all burnt the valve was still fixed by the exact valve ball body. Floating trunnion mounted j d controls mfg.
