Hamilton Sundstrand Company Gas Fuel Metering Valve HFG2.0 - Manual (Page 12)

6 HFG2.0 USER GUIDE
The HFG2.0 includes four (4) 0.50-24 UNC-2B mounting holes with
stainless steel heli-coil inserts for securing the valve body. The mounting
holes on the standard version of the HFG2.0 are located on the opposite
side from the electrical connectors. The mounting holes on the reversed
version of the HFG2.0 are located on the same side as the electrical
connectors (see Figure 1-5).
Figure 1-6 shows mounting provisions for the 3-piece housing version of
the HFG2.0. Figure 1-7 and Figure 1-8 show mounting provisions for the
1-piece housing version of the HFG2.0.
Note: Provide adequate clearance to the OUTLET port to facilitate
cleaning.
Lifting Considerations
The aluminum body HFG2.0 weighs approximately 100 lbs. The stainless
steel body HFG2.0 weighs approximately 190 lbs. PECC recommends
using the 0.375-inch diameter clevis to lift the valve, in conjunction with
the appropriate lifting equipment.
Note: The clevis exceeds the Factor of Safety (FOS) requirement
of 3, based on component yield strength, per ASME B30.20-
1999.
WARNING
Lifting Hazard – Do not attempt to hand-lift the actuator. Use
appropriate lifting equipment.
Connecting the Clevis
The clevis can be used to secure the actuator end of the HFG2.0. A high-
strength shoulder bolt (0.375” diameter) is recommended to fasten the
clevis to a user-provided mount bracket.
The clevis can be rotated to any orientation to support installation. Loosen
the four retaining screws and rotate to the desired angle. The screw
pattern can be indexed
± 45 degrees to provide additional adjustment.
When adjustments are complete, torque the four retaining screws to
117-138 in-lbs.
