Features

In process industries, fire-safe equipments are often required for petroleum and flammable applications. For ideal fire-safe valves, Series FSB 2D Direct Mount 2-Piece Fire-safe Full Port Flanged End Ball Valve in ANSI Class 150 and Class 300, DIN PN16 and PN40, where maximum flow capacity and minimum pressure drops are required. Series FSB 2D conforms to API 607 5th Edition with fire-safe features, including fire-safe contact, graphite seals, and anti-static devices. The API 607 certification, which is equivalent to ISO 10497, is designed to test soft seat quarter turn valves, where valves are tested under high temperature condition (above 750°C) for certain period of time.

The fire-safe design consists of three elements: fire-safe contact, graphite seals, and anti-static devices. Fire-safe contact is a precise machined metal ring surface to fit with the valve ball after the soft ball seat has been burnt away by high temperature heat. The firesafe ontact acts as a metal seat, and together with the floating ball pushed downstream, the tight-shutoff secondary seal is formed even without the presence of soft ball seat. In the body connection where main body and end cap are connected, PVS FLOW CONTROL offers dual body seal to achieve non-leakage externally with PTFE and graphite rings. PVS FLOW CONTROL also provides anti-static device for all FSB 2D ball valves. Electrical charges can be grounded with anti-static device, to avoid potential danger.

For flange facing option, PVS FLOW CONTROL offers raised face flange for use with most general applications. For special or high pressure applications, please consult with PVS FLOW CONTROL representatives.
