The B/Mc Valve
This water truck spray valve was
designed by Herman Bertolini and has been manufactured in the USA
continuously since 1971.
Model 71 B/Mc water truck spray valves are a simple, durable design, proven in use since 1971, and honored by imitations.
Normally closed, this valve will not leak with loss of control pressure. An adjustable orifice allows control of spray pattern and volume. A grooved inlet provides flexibility in mounting and positioning to achieve desired spray coverage.
Air actuated for most applications, with 12VDC or 24VDC control available for vehicles that do not have an air system.
B/Mc is pronounced "bee mack"
