Hydraulic Actuation, Local Resetting Deluge Valve, Pressure Control Series 700D/DG/DX - 04/14AR01

General Description

T h e I n b a l P r e s s u r e C o n t r o l , Hydraulically Actuated Deluge Valve is specifically designed for use in fire protection systems which require pressure control, actuated by a detection and release system of wet pilot sprinklers and/or hydraulic manual control. The Inbal Valve, when in operation, automatically reduce a higher inlet pressure to a preset delivery pressure which remains steady and unattached by the variations or fluctuations in the pressure inlet line.T h e I n b a l P r e s s u r e C o n t r o l , Hydraulically Actuated Deluge Valve is used for automatic or manual hydraulic operation. The wet pilot line functions as a thermal detector equipped with fixed temperature release. When one or more of the sprinkler heads located on the pilot

line fuses, or when a manual release station is operated locally or remotely, the Inbal Deluge Valve opens to allow water to flow from all open sprinklers and/or nozzles on the system.While the valve operates, the deluge system pressure is maintained at the preset level within a narrow range. If the downstream pressure changes slightly the pilot control responds immediately to modulate the Inbal Valve for the preset pressure. The use of the Inbal Pressure Control Deluge Valve balances the distribution of the water capacity available, throughout the system and prevents a higher demand from the areas which are of lower altitude or are located closer to the pressure source. Thus, the total system demand is balanced and the excess flow

through the system with high pressure water supplies is reduced to the desired level. The adjustment of the valve's delivery pressure can be easily modified at the site.Standard material Inbal Pressure Control Deluge Valves are rated to 300 psi (21 bar) and are available in sizes 1" (40 mm) to 12" (300 mm) with threaded, flanged, grooved, or wafer ends. The only moving part in the Inbal Valve, when it operates, is the reinforced sleeve which forms a drip tight seal with the corrosion resistant core. It has a smooth opening to prevent any water hammer in the piping system .The unique design of the Inbal Valve and the pilot control, and variety of materials and coatings, make the Inbal Pressure Control Deluge Valve suitable for use with brackish or sea water similar to t hose found i n chemica l and petrochemical facilities or in offshore platforms.

Operation

The Control Chamber of the Inbal Automatic Water Control Valve is the annular space between the Valve Housing and the Sleeve. The valve is held in a closed position as long as inlet pressure is maintained in the Control Chamber. The wet pilot line, equipped with closed sprinkler heads, is pressurized through the valve trim and located over the protected area. The wet pilot line serves the dual purpose of thermal detection and release system.In the set position, water pressure is applied to the Control Chamber of the Inbal Deluge Valve and to the hydraulic release system from the upstream of the Water Supply Valve. Consequently, the Inbal Deluge Valve stays closed.The Inbal Deluge Valve opens when one or more of the sprinkler heads installed on the wet pilot line fuses and water pressure is allowed to escape, or when a hydraulic manual release opens.Either one of these operations releases water from the Deluge Pilot Valve which opens to release water from the Inbal Valve Control Chamber. The flow through the Pressure Reducing Pilot Valve responds to changes in the downstream pressure while controlling the pressure at the Inbal Valve Control Chamber. When the delivery pressure decreases, the pilot valve and the Inbal Valve open wider to increase the pressure. When the delivery pressure increases, the pilot valve and the Inbal Valve close to throttle further the flow

and consequently the delivery pressure is decreased. Thus, the outlet pressure is maintained within a close limit. The operation of the Inbal Deluge Valve will flow water from any open sprinklers and/or spray nozzles on the system while activating the system's alarm devices.Once the Deluge Pilot Valve operates, it latches in an open position, preventing the Inbal Pressure Control deluge Valve from closing even if the open releasing wet pilot line closes. The Inbal Valve will close only when the Resetting procedure is followed.The Deluge Pilot Valve spring tension is adjusted to open wide when the wet pilot line operates and to be in a drip tight closed position when the wet pilot line is reset. The Emergency Release Valve is used for emergency actuation of the Inbal Deluge Valve and for routine testing.

Automatic Water Control Valve Series 700D

F02-01-01

General DescriptionThe 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 mater- ials and coatings make the Inbal Auto-matic 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 1" (40 mm) to 12" (300 mm). The valves have threaded, flanged, or wafer inlet and outlet ends.

Full open operationWhen pressure in the Control Chamber is relieved to the atmosphere, the Inbal Valve opens wide. The sleeve assembly is safely enveloped by the housing.

Tight closing operationWhen pressure from the valve inlet (or an equivalent independent operating pressure) is applied to the Control Chamber, the Inbal Valve closes drip tight. The fabric sleeve safely envelopes the resilient sleeve giving full support.

Modulating actionA stable throttling position is obtained when a quantity of pressurized fluid is held in the Control Chamber. It is the amount of fluid in the Control Chamber that determines the position of the sleeve assembly. The Control Chamber can be alternately filled or exhausted to achieve the desired operating condition.

Operation

The Control Chamber of the Inbal Automatic Water Control Valve is the annular space between the valve Housing and the Sleeve. The valve is held in a closed position as long as inlet pressure is maintained in the Control Chamber. In the set position, the water pressure is transmitted from the upstream through the valve trim to the Control Chamber, and the Inbal Valve stays closed. Actuation of the valve by a manual, hydraulic, pneumatic, or electric release system allows venting of the pressure in the Inbal Valve Control Chamber, and the valve opens wide, permitting a flow of water to the piping system. When a pressure or flow control is added, the Control Chamber is monitored to modulate a preset delivery pressure, maximum inlet pressure, or flow rate.The principle of operation is illustrated in Figures (1) through (3). The nominal pressure losses are shown in Graph (1).

The Flow Factor Cv (Kv) is defined as 3the flow rate in gpm (m /h) of liquid at

0 068 F (20 c), flowing at 1 psi (1bar) head loss.

Q = Flow rate in gpm.

Cv = Flow factor.

QCv ( )
