Gas Metering Valve
The gas metering valve is a direct-acting proportional SERVOID® valve driver provides linear proportional control of the metering orifice which yields linear proportional flow. This valve features a suspended-armature design that is inherently reliable and results in very low hysteresis. Elastomeric diaphragms provide pressure balancing and flow path isolation. This particular design will operate from a few inches of water column pressure up to 100 psig with flow rates up to 250 SLPM of air or oxygen at a 10-psi pressure drop.
