Butt Welding Double Block And Bleed Ball Valve F316 Body 600LB 1/2’’

Data Sheet

Butt welding ball valve is provided with reliable sealing and smooth flow channel so as to ensure accuracy of opening and closing through small fluid pressure loss and stable flow channel.

Bolted construction allows easy service and on site maintenance.

When the valve is closed and the middle cavity is emptied through the discharge valve, the upstream and downstream seats will independently block the fluid at the inlet and outlet to realize double block function.Another function of the discharge device is that the valve seat can be checked if there is any leakage during the test. ln addition, the deposits inside the body can be washed and discharged through the discharge device to reduce damage to the seat by impurities in the medium.

When the waste in the inner cavity is discharged through the drain valve, there will be pressure between the inlet and outlet ends of the compression seat, which makes it easier to achieve the sealing performance.
