Automatic Water Control Valve Series 700DG
The Inbal Automatic Water Control Valve series 700DG is a pressure operated, sleeve actuated, axial valve, designed from basic concepts, with a built-in actuator, to function as a control valve in fire protection systems.
The Inbal series 700DG is used as deluge, preaction, dry pipe, remote 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 700DG 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 700DG is available in sizes 1½” (40 mm) to 12″ (300 mm). The valves have threaded, flanged, grooved, or wafer inlet and outlet ends.
The Inbal Valve series 700DG is supplied with drain ports (¾”, 1½”, or 2″) on the valve inlet and outlet ends. The drain connections can also be supplied on Drain Ends which can be attached to the valve ends.
