 
The Inbal Automatic Control
Valve is a pressure operated, sleeve actuated valve designed
from basic concepts, with a built in actuator to function
as a control valve in fire protection. The
Inbal Valve utilizes the unique N.M.M.P. (No Moving
Mechanical Parts) design which ensures a long life of dependable
operation. The small physical dimensions and the low weight
