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

1)DBB ( double block and bleed ) design :

The drain and venting device releases the sensor material within the central cavity of the valve body when the ball is in the fully open or closed position. In addition, the overload pressure in the central chamber of the valve can be released to the low pressure side through the dump.

2)Emergency sealing design :

The API 6D Ball Valve is designed with a composite injection hole that is mounted on the stem/bonnet and seat or side cover support. This compound can be used for a second seal when the stem or seat seal is damaged and causes a leak. A hidden check valve is mounted on the side of each composite injection valve to prevent compounds from flowing out due to the action of the transmitter material. The top of the compound injection valve is the connector for quick connection to the compound gun.

3)Autamatic body cavity relief design :

When the valve body pressure of the API 6D Ball Valve rises abnormally and becomes unstable, the valve seat downstream of the trunnion will be pushed by the abnormal pressure, and then the pressure will be automatically released without damaging the seal of the upstream seat. Abnormal pressure in the float valve body directly releases pressure into the upstream pipe without damaging the seal of the downstream seat.
