CAPACITIES

MCOV MICRO-CAM OIL VALVES
B SERIES VALVES
The B series Micro-Cam Oil Valve capacities cover the normal range of most industrial combustion applications.
These valves travel from 0 to 180°, i.e., closed to full open, and have a linear flow curve at a constant differential
pressure over the entire flow range. For example, the flow at valve position 18 is two times greater than at valve
position 9.

F,G, & K SERIES VALVES
The F,G, & K series Micro-Cam Oil Valves are high capacity valves with the same basic construction and operating
features as the B series except for minor design variations; 120° travel form closed to full open position to facilitate
automatic control, and a non-linear flow curve at a constant differential pressure over the entire flow range. The nonlinear flow curve indicates that the flow is not directly proportional to the valve position. For example, the flow at
valve position 12 is not necessarily two times greater than at valve position 6.

NOTES:
1. Capacities based on No. 2 fuel oil at .849 s.g. and 60°F.
2. Pressure drop across full open valve. Actual test data measured at 25 psig pressure drop, all other capacities calculated.
3. When ordering, specify if valve is to be equipped with hand lever, hand wheel or adjustable radius lever for automatic
control.
