Description

The system is available in two primary configurations. The “Swift” configuration

provides either single- or dual-metering valves in a single housing. This

configuration can be integrated into a new or existing gas metering system to

provide low-cost, accurate, reliable control. The Swift Model 200 system, sizes

65. 36. and 20. have been designed to provide system mass flow accuracy of 2%

of point at 100% of rated flow across the entire temperature range. The Swift

Model 200 system, size 11. has been designed to provide system mass flow

accuracy of 6.2% of point between 50 and 100% of rated flow, across the entire

temperature range.

The Swift gas metering system components include one or two metering valves

and one valve driver (see Figure 1-1). For fuel systems requiring two

independently modulated fuel flows, the primary valve can be integrated with a

secondary metering valve. The primary valve can accommodate this integration

without duplicating either electrical or mechanical connections.
