Deluge valves are hydraulically operated differential type valves used to control water supply to a deluge system. Deluge systems use open sprinklers or nozzles. Trim sets are used to control the operation of the valve.
radio works 25 watts but if it is valve radio then it works like this listen... turn the volume high enough and quickly do the tone then just tap the off button and turn it on then everything will be installed in it and press play or some others thats the hacked way guys thanks.
when the pressure increases over the maximum allowable working pressure of the vessel, the valve will open to protect against overpressure.
The easiest way is to install two pressure gauges (If reducing pressure) either side of the reducing valve, you will then have indication of upstream pressure and down stream pressure, of which you can adjust to suit you process.
Screw down non return valves only allow a liquid to be passed one way through it. Even when the valve is in open position valve lid is on the seat unless any liquid is pressurized from its inlet side.Any back flow will be restricted.
Sounds like you have a bad zone valve or zone pump. There is either a pump, and the zones in the house have zone valves, or each zone has it own pump. Zone valves go bad all the time, you can just replace the motor on it instead of sweating the new valve in. The box that is on top of the valve.

A Deluge System can be activated by the following 1. Manually 2. Electrically (Fire Detectors) 3. Pheumatically (Glass Bulb Detectors) 4. Hydraulically (Glass Bulb Detectors) Each of these methodes (2 3 4) has a fire detection line that can activate the deluge valve Once the Detector operates the deluge valve will be activated, releasing (opening) the water supply to the system. Autommatic Fire Pumps can be activated by this proceedure and inturn extinguish/control the fire condition.
deluge valve work from close position to open position to release the material to shut off the fire once it receive a signal from fire detector, installed in a system.
No, sprinklers in a deluge system are "open"; no valve in the sprinkler, and an automatic valve turns on the water to all open sprinklers when a fire condition is detected.
It's type of valve used in fire water system for fire protaction.

The duration of Before the Deluge is 2.3 hours.
A deluge fire sprinkler system, unlike most ordinary systems, mean that the sprinkler heads do not have individual heat-sensitive valves. The sprinkler heads in a deluge system have no valves of their own, meaning they are always open and water will be sprayed out of them when the supply valve is turned on. There are limited uses for deluge systems, such as in a tire storage warehouse where it is important to put out a fire quickly and the massive flow of water will not cause major damage.
Noun
When it rains two inches in a day, I'd call that a deluge. When the rock I threw struck the large hornet's nest, a deluge of bees came storming out and stung me. The deluge destroyed my hat. When we got to the bridge, we were surprised by the deluge. Noah received advance information about the deluge and built an ark. The sprinkling of rain quickly became a deluge.
A Deluge System is a fixed fire protection system in which the pipe system is empty until the deluge valve operates to distribute pressurized water from open nozzles or sprinklers.Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection systemDeluge Fire Sprinkler Systems differ from conventional Fire Sprinkler Systems in the sense that all sprinkles or nozzles employed in the system are open and when water is released into the system it flows from all discharge devicesDeluge systems are used in places that are considered high hazard areas such as power plants, aircraft hangars and chemical storage or processing facilities. Deluge systems are needed where high velocity suppression is necessary to prevent fire spread.
