Swagelok’s AFS ball valves offer high pressure, flow

Solon, OH—With working pressures up to 6,000 psig (413 bar) at 250 °F (121 °C) and flow coefficients from 4.0 to 13.8, Swagelok reports that its new alternative fuel service (AFS) two-way ball valves meet the demands of hydrogen and compressed natural gas applications.

Solon, OH— With working pressures up to 6,000 psig (413 bar) at 250 °F (121 °C) and flow coefficients from 4.0 to 13.8, Swagelok reports that its new alternative fuel service (AFS) two-way ball valves meet the demands of hydrogen and compressed natural gas applications. The valves’ certifications include ANSI/NGV 3.1 service valve certification to 3,600 psig (248 bar) and ANSI / NGV 4.6 Class B certification to 4,500 psig (310 bar). Swagelok develops and manufactures fluid system component technologies for the research, analytical instrumentation, process instrumentation, pharmaceutical, oil and gas, power, petrochemical, and semiconductor industries.

The firm adds that a unique, ultra low-temperature fluorocarbon O-ring material seals across the valves’ full temperature range of -40 to 250 °F (-40 to 121 °C). Swagelok says its robust, spring-loaded, patent-pending seat design doesn’t require adjustment after the valve is installed. In addition, all wetted components of the AFS ball valve are compatible with hydrogen and compressed natural gas (CNG).

Swagelok’s fractional and metric tube fitting end connections provide gaugeable make-up and consistent, leak-tight connections. ISO and NPT end connections are also available. Users can choose from a heavy-duty quarter-turn directional handle, a Swagelok rack and pinion pneumatic actuator, or an ISO 5211-compliant rack and pinion pneumatic actuator.
