The Inbal Automatic Water Control Valve series 700DX 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 700DX is used as deluge, preaction, dry pipe, remote control, pressure reducing, and in 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 700DX 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
onlymovingpartwhentheInbalValve 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 as well as water foam concentrate.
The Inbal Automatic Water Control Valve series 700DX is available in sizes 11⁄2″ (40 mm) to 12″ (300 mm). The valves have threaded, flanged, or wafer inlet ends, and threaded, flanged, grooved, or wafer outlet ends.
The Inbal Valve series 700DX is supplied with drain ports (3⁄4″, 11⁄2″, & 2″) on the valve outlet end. The drain connection can also be supplied on a Drain End which can be attached to the valve outlet end.
