Notes:
1. Capacities based on air @ 1.0 s.g. and natural gas @ 0.60 s.g., and 60°F fluid temperature.
2. Δp measured across valve.
3. Maximum inlet pressure is 5 psig, maximum operating temperature is 250°F.
4. 1xx and 1xxx series are manual valves with a short lever and locking screw; 4xx and 4xxx are automatic valves with a long
lever and linkage connector.
5. For applications requiring a control motor mounting bracket, specify the motor model number when ordering.

(Hot air BVA-H valve capacities on reverse side.)
