- Features
- In applications where economical fire-safe ball valves are required, Series FSB 22 is the first choice. The Series FSB 22 has been firesafe approved and certified with API 607 4th edition. In addition to the general fire-safe design, Series FSB 22 has special 360° all around welding design to prevent external leakage. The end cap is welded together around the valve body, and cannot be separated permanently. The fire-safe design provides high pressure rating and higher temperature endurance.
In process industries, petroleum and flammable applications often require fire-safe equipments. For ideal fire-safe valves, DIE ERSTE offers Series FSB 22 Mounting Pad 2-Piece Fire-Safe Full Port Ball Valve 2000psi, where maximum flow capacity and minimum pressure drops are required. Series FSB 22 meets API 607 4th Edition with fire-safe design, including fire-safe lip, graphite seals, and anti-static devices.
The fire-safe design is consist of three elements: fire-safe lip, graphite seals, and anti-static devices. Fire-safe lip is a precise machined metal ring to fit with the valve ball after the soft ball seat has been decomposed by high temperature heat. The fire-safe lip acts as a metal seat, and together with the floating ball pushed by downstream, the tightshutoff secondary seal is formed even without the presence of soft ball seat. In the body connection where main body and end cap are connected, DIE ERSTE offers dual body seal to achieve non-leakage externally.
DIE ERSTE also provides anti-static device for all FSB 22 ball valves. Small metal ball and spring are inserted into the bottom and the side of valve stem. With anti-static device, charges caused by valve operation can be discharged and grounded, and eventually to prevent explosion by electric charges.
