Pressure Reducing Valve

Advantages: Increases the system equipment life and save the water in tank which is used for unnecessary operations. These valves are used to reduce the pressure which is over the limits on the system. After hydraulic calculations, users obtain the design pressure, after that users do same hydraulic calculations for the other areas. In this areas fire pump are selected according to the highest pressure. For this pressure adjustments pressure reducing valves are used. Users have use manometer with these valves in front and back. By the output of the valve pressure reducer ½ ” provided that it is not smaller than the relief valve should be used. May not exceed 12.1 bar relief valve setting pressure.

Relief (Pressure Reduce) Valves

This valves using for the preventing damages which cause from the pressure in fire pump systems. Generally fire protection systems use the diesel pumps and electrical motors. In that systems relief valves are preferred.

Resilient Wedge OS&Y Gate Valve

Resilient Wedge OS&Y Gate Valve

OS&Y gate valve is developed to be used as the cut off and zone control valves in order to substitute supervisory switched butterfly valves in the fire security systems. Just to make them visible and traceable inside the systems, they are preferred to be used with post indicators instead of wheels. Valves could be commanded to get on/off by using post indicators and the valve positions could and traced. These valves also suitable for indoor and outdoor applications. Disadvantages: Not smaller than the other valves, and non-economic.

Supervisory Switch Butterfly Valve

Supervisiory switch butterfly valves are produced for separating the zones and act like control valves. In fire protection systems, valves have to can be monitored. They are provided with a hand wheel mounted on the shaft communicates with the gear box for positioning. This way, users can have information about automation system and improved equipment in order to see easily on the valve body. It is suitable for using at indoor or outdoor. Advantages: To compare with other valves, this type of valves takes less area. Disadvantages: For other valves, it has more pressure loss.

Test and Drainage Valves

In sprinkler systems, these valves are used for the testing systems and drain the unnecessary fluids from the systems. Advantages: They have sight glasses in their body,single valve is sufficient to drain the line. For choosing the test and drain valves, users should pay attention to line diameter. Also these valves have to have same diameter with the sprinkler orifice diameter.

Warehouse Type Sprinklers

Warehouse type sprinkler is designed for the special applications such as high level storage systems. These type of sprinklers gives the more water with more less pressure. If the users do correct pressure adjustments for ESFR Sprinklers, users don’t need any other sprinkler use for the between shelf. These models design for the protect the shelf breaks. But in using these sprinklers users have to attention for features of sprinklers. Heat detection, sprinkler cover case is important. If the water shield doesn’t use in that system, sprinkler can’t reach estimated heat and don’t activate it.
