2) Valve Details
1. Needle Valve
With the help of this valve flow control at a very low rate with higher accuracy is possible. Needle valves are smaller in size. So, there is not an issue of space during its installation. |
2. Locked structure
When no locking hole in the fully open or fully closed position of the valve. Locking structure, safe and reliable. |
3. Lever operation
The main feature of DBB valves design is that it has two balls in one valve to ensure greater safety. Two balls design with two lever operated. |
4. Flange face end
The Ring Type Joint flanges are typically used in high pressure(Class 600 and higher rating) and/or high temperature services above 800°F (427°C). They have grooves cut into their faces which steel ring gaskets. |
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.
