  1. Deluge systems are used in conditions that require quick application of large volumes of water. They create a 'buffer zone' in hazardous areas or in areas where fires can spread rapidly. They can also be used to cool surfaces to prevent deformation or structural collapse. Or to protect tanks, transformers, or process lines from explosion.

  2. May 14, 2018 · Introduction The Hydraulically Controlled On-Off Deluge Valve is an elastomeric, hydraulic pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The Hydraulically Controlled On-Off Deluge Valve is activated by a hydraulic relay valve, by which opening and closing of the valve can be controlled remotely. The Hydraulically ...

  3. May 11, 2018 · The deluge valve (assembled with a specific fit) is suitable for systems that include adequate detection systems and open nozzle pipelines. The deluge valve prevents water from entering the system piping until it is needed. The deluge valve is maintained closed by pressure applied to the control chamber through a restricted priming line. In the ...

  4. Jul 24, 2013 · In Deluge systems, we use open sprinklers or nozzles and a deluge valve to control the fire. when a fire is detected (by means of a fire detector) a signal is sent to the deluge valve to open. When it opens, water flows into the piping system and discharges from all sprinklers at once. Deluge systems are used where large quantities of water are ...

  6. Mar 21, 2021 · A heat pump reversing valve is an electromechanical four-way valve and it is used in a heat pump to reverse the flow of the refrigerant and the change in the flow direction of the refrigerant is done with the help of an electrical magnet. Many companies are manufacturing reversing valves but all of these valves have the same general configuration.

  7. Mar 19, 2021 · These tanks are mostly a closed system, this tank doesn’t consume water. The water that is injected during the low-pressure events would be removed after the situation is changed. The water is removed during the high-pressure event after the pressure drop. Mostly the surge tanks are powered by air so that they can remove or add water very faster to counter the pressure changes.

  8. Mar 25, 2021 · A bellow seal valve is a control valve that doesn’t have a conventional gland packing and instead of that these valves have a bellow cartridge and this would be welded to the valve’s bonnet and stem. The bellow can be compared to a coiled spring because it can be flexed in compression or in extension. The bellow seal valve is similar to a ...

  9. Jan 9, 2017 · Monitor Module - As the name implies, it only monitors the status of the interfaced device. Eg : Engine Run, Flow Switch, Alarm Check Valve. Control Module : It is just a relay which changes NC / NO in case of fire which controls the device Eg : Sliding Door, Elevators, Exhaust Fans. Upvote (1) Downvote Reply () Report.
