Description

Test and drain valve is used to conduct testing and maintenance on sprinkler systems. Thanks to its orifice available in different sizes it creates a flow equivalent to the flow passing along one sprinkler only and enables tests of alarm devices on the lines for checking purposes in the case of a sprinkler water flow. The orifice diameters of the smallest sprinkler and the test drain valve in the system should be equal. It is also used as a drain valve to discharge water in the piping by changing the position of the valve. It includes a sight glass to observe the flow.

Wet Alarm Valve

The wet alarm valve is designed for applications where the water is unlikely to freeze. The water staying pressurized in the pipes is released over the fire area after the sprinkler is activated due to fire. The pressurized water system is not only feed contionuously, but also fills in the retard chamber. After the chamber is filled, the pressure switch on the chamber is actuated. The pressure switch sends the alarm information to the fire warning system or the automation system. After the pressure switch is actuated, the water is delivered to the water-motor gong and releases a mechanical alarm.

Sprinkler

Duyar sprinkler is easy to use and extremely safe. Sprinkler is placed on the specially designed piping system such that iscovers the area requiring protection. One of the most significant components of the stuffing, the fluid in the glass tube expands and goes off due to the temperature generated by fire. Because the ambient temperature exceeds the maximum expected ambient temperature by 30°C during fire, the maximum ambient temperature of the sprinkler should be shosen tobe at temperatures above 30°C. Once the glass tube of the sprinkler above fire, the water under pressure hits the deflect and sprayed over fire. Only the sprinkler heating up during fire goes off, thereby releasing water.Duyar Valve Sprinkler Product List;
