ZFV API 6D trunnion mounted ball valve have delow design :

DBB ( double block and bleed ) design :

When ball is full open or close position,the transmitter substance in center cavity of body can be released by drainage and emptying devices.In addition,the over loaded pressure in the center cavity of valve canbe released to low pressure end by self relief seat.

Emergency sealing design :

Compound injection holes are designed and compound injection valves are installed at locations of stem/cap and body seat or support of side bonnet. When sealing of stem or seat is damaged to induce leakage,the compound can be used to do the second time sealing.A concealed check valve is installed in side of each compound injection valve to prevent compound from outflowing due to the action of transmitter substance.The top of the compound injection valve is the connector for fast connection with compound injection gun.

Autamatic body cavity relief design :

When the body pressure going up un-normally as the unstable factor,the trunnion ball valve downstream seat will be pushed by un-normally pressure,and then release the un-normally pressure automatically,it does not damage to the sealing of upstream seat.The unnormal pressure which in the floating ball valve body will release the pressure into the upstream pipe directly,it doesn't damage to the sealing of the downstream seat.
