YF 3010 Series EMA High Temperature Choked Flow Gas Control Valves

The Young & Franklin 3010 Series sonic flow Gas Control Valves (GCVs) are electro-mechanically actuated (EMA) to provide excellent speed and valve position accuracy. This GCV electronically homes on power cycle and has a turndown ratio of ~100:1.  The entire YF 3010 Series is certified for use in hazardous locations around the world and available in a range of sizes suitable for industrial or power turbines of any size.

The valve body is coupled to an actuator assembly that contains a fail-safe spring to quickly close the valve, halting fuel flow in the event of a power failure or turbine trip condition.  Shock absorbers protect the actuator drive mechanism and valve seats during rapid closing thus ensuring reliable operation, and independent position feedback can be obtained via 2 optional LVDTs.  The complete system provides precise fuel flow delivery with reliable operation. No routine maintenance is required.
