Fire Safe Ball Valve Design

Australian pipeline valve apv api6d trunnion mounted ball valves include features such as.

Fire safe ball valve design. 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. Both floating trunnion mounted fires safe ball valves. Floating ball valve has been approved and should also qualify a trunnion ball valve. Floating trunnion mounted j d controls mfg.

Fire safe valves are spring loaded can stop the fire flow automatically and reduces the chance of leakages. 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. Floating trunnion mounted j d controls mfg. Anti static devices are built in the valve stem to ensure electrical continuity between ball stem and body.

The delicate seats were all burnt the valve was still fixed by the exact valve ball body. Modentic s flanged ball valve line includes one piece two piece three piece and wafer type construction. There is a big risk when accepting the low level fire safe design especially when no tests have been done at all. 160 was endorsed with split body flanged pedal to the metal configuration belleville washer and graphite gasket stem pressing.

Controlling the flow of combustibles these spring loaded valves said to be very effective against any damage. 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. For higher sizes and pressure ratings trunnion mounted ball valves are preferred by industry. 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. Fire safe valve was planned when the plant is under fire. Fire safe design ball valves fire safe valves are designed to prevent the fire from the fuel valve if gets damaged or leaked. We will talk about the ball valve fire safe design from perspectives of internal leakage prevention and external leakage prevention.

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 approval are also equipped. Higher size ball valves are designed with stem bearing to absorb radial loading on the stem. This will keep the harm as low as would be prudent.

Thus providing greater safety while handling volatile media. The first method to achieve a fire safe design by using a fire proof component usually is referring as an inherently fire safe valve.
