Blow-off Design



When the valve is closed, the pressure in the body cavity will be

accumulated , and the pressure is removed by opening the blow-off

valve. 





drainvalve


Drain Valve Design 


The seal of the trunnion ball valve is achieved by the floating seat.When

the waste of the inner cavity is removed through drain valve, the

pressure will exist between the inlet and outlet end of the compression

seat, and it is easier to achieve the sealing performance.

This structure leads the electrostatic spark to the earth caused by the  friction between the 

ball and the seat. This structure could avoid the fire disaster and explosive accident.
