Automatic Water Control Valve Series 700D
The Inbal Automatic Water Control Valve series 700D is a pressure operated, sleeve actuated, axial valve, designed from basic concepts, with a built-in actuator to function as control valve in fire protection system. The Inbal series 700D is used as deluge, preaction, dry pipe, remote control, pressure reducing, pressure relief, pump control, water level control, and other types of control valves.
The standard material Inbal Valve is rated to 300 psi (21 bar) and requires a minimum line pressure of 20 psi (1.5 bar) for operation. Upon removal of the control pressure the Inbal Valve opens instantaneously, yet very smoothly, to prevent any water hammer in the piping system. The Inbal 700D performance and ease of resetting are not affected by vertical or horizontal installation. The Inbal Automatic Water Control Valve utilizes the unique N.M.M.P. (No Moving Mechanical Parts) design. The only moving part when the Inbal Valve operates, is the reinforced sleeve which forms a drip-tight seal with the corrosion resistant core. The Inbal design also prevents false operation due to transient surges in water supply pressure. The N.M.M.P. design and variety of materials and coatings make the Inbal Automatic Water Control Valve ideally suitable for use with brackish or sea water similar to those found in chemical and petrochemical facilities or in offshore platforms. It can also be used as a foam concentrate control valve in foam/water systems.
The Inbal Automatic Water Control Valve series 700D is available in sizes 1½” (40 mm) to 12″ (300 mm). The valves have threaded, flanged, or wafer inlet and outlet ends.
