Deluge Systems are intended to deliver large quantities of water over a large area in a relatively short period of time. The Inbal Deluge Valve is FM and VDS approved to 300 psi (21 bar) in sizes 3", 4", 6", and 8" (80, 100, 150, and 200 mm).
The Inbal deluge Valve is compact, lightweight, and is provided with a preassembled trim - all of which minimize the installation time and make it simple and easy. The Inbal Valve opens fast, yet smoothly, preventing water hammer. The Inbal Valve design prevents false tripping and it can be reset by a thumb-activated knob.
The Inbal Remote Control Valve is used whenever monitoring and controlling the whole area is done from a control room or control panel. Remote operation of the system is needed for reducing heat transfer and for cooling purposes. Remote resetting of the systems is vital for effective use of the limited water/foam capacity and to reduce drainage problems.
The innovative design of the control trims whereby all the components are built in one body and the use of external tubing is virtually eliminated, makes the Inbal Valves function ideally for the purpose of remote control.
This Inbal Valve combines a deluge and a pressure control function in the same valve. The requirement for pressure control is typically associated with a large system where the fire pump is designed for the capacity of several deluge systems.
When only part of the deluge system is operated, the delivery pressure to each system should be reduced to meet the components' pressure rating and to prevent flooding by use of excess flow. When several deluge systems operate simultaneously, the pressure control deluge valves ensure balancing of the water pressure resources and efficient use of the overall capacity.
The Inbal dry pipe system is a sprinkler system employing automatic sprinklers installed on a piping system containing air or nitrogen under pressure.
This dry pipe valve is used to hold back the water supply and to serve as the water / air interface. It is designed so that a moderate amount of air pressure will hold back a much greater water pressure. When a fire occurs and enough heat is generated, one or more sprinklers will operate.
The system's air pressure will then escape through the open sprinkler(s) and drop to a predetermined level to allow the dry pipe valve to open. Once the dry pipe valve opens, the water supply will be admitted into the sprinkler system piping to fill it, and water will discharge from any sprinkler(s) that have operated.
Dry pipe systems are used in environments that may be subject to freezing temperature.
Inbal Dry Pipe Valves are FM approved to 300 psi (21 bar) in sizes 3", 4", 6", and 8" (80, 100, 150, and 200 mm).
The Inbal Preaction System employs a piping system with closed sprinklers pressurized with supervisory air or gas pressure.
The system is equipped with a supplemental detection system whose function varies depending on the type of preaction system. The types of detection systems most commonly used are pneumatic or electric actuation.
Preaction systems are used where it is important to prevent an accidental discharge of water, when an alarm is desired in advance of sprinkler operation, or when it is desired to reduce the water delivery delay inherent in a dry pipe system.
Pressure Relief Valve
The Inbal pressure relief valves are used to release excess pressure that may develop as a result of a sudden change in the velocity of the water flowing in the pipe.
Pressure Sustaining Valve
The Inbal pressure sustaining valves are used to sustain the system pressure to a predetermined maximum level. The applications balance the pressure distribution throughout the whole system by maintaining the minimum pressure for high altitude users. Pressure sustaining valves are also used to prevent discharging of the pipe system when any user starts to operate.
Pressure Reducing Valve
The Inbal pressure reducing valves maintain a predetermined outlet pressure which remains steady and unaffected by either changing of inlet pressure and/or various demands. Inbal Pressure Reducing Valves are self contained control valves which do not require external power
