1) Parts Material
| Body | ASTM A105 | Stem | A182 F6a |
| Ball | A105 with ENP | Seat | A182 F304 |
| Seat inserts | DEVLON | Seals | VITON |
| Bolt | A193 B8M | Nut | A194 8M |
2) Valve Details
 |
1. Forged three-piece housing two balls
The main feature of this design is that it has two balls in one valve to ensure greater safety. |
 |
2. Bolted bonnet connection
ZJCLV ball valve adopts the standard bolts and nuts. It could extend the valve longer service life. |
 |
3. Double block and bleed design (DBB)
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. |
 |
4. Drain Valve Design
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. |
3) Advantages
1. Saving in weight, space, and installation time.
2. Reducing the leakage pathways into the environment.
3. Increasesd reliability of the system.
4. Fire safe & anti-static.
