Gas-Metering Valve For Power-Generation Systems

The directacting proportional Servoid valve features a suspended-armature design that is reliable and results in low hysteresis.

The gasmetering valve provides linear proportional control of the metering orifice that yields linear proportional flow. The valve can be calibrated for supply pressures to 100 psig, and flow rates to 1,500 scfh (80 lb/hr) of natural gas at a 10-psid pressure drop are possible. Additional configurations are available for use with propane, oxygen, carbon dioxide, nitrogen, hydrogen, methane, and sour/bio gas.
