Pressure Reducing Control Valve
Pressure reducing control valve are valves that have the function of reducing the pressure value to the appropriate level. Pressure reducing control valves, which reduce high pressure values to the appropriate level, do this with the help of pilot valves mounted on the upper part. Pressure reducing control valves automatically close themselves when there is no water cycle in the system. In case the determined pressure value is high, it comes back to the open position automatically. Pressure reducing control valves operate with the normal pressure of the system. Therefore, there is no need for any extra energy.
Pressure reducing control valve are high precision valves that can be easily adjusted according to the pressure level requested. These valves, which are located in the system and keep the pressure value at a stable level, continue to operate in case the flow rate decreases. In this context, it is possible to say that pressure reducing control valves are not affected by changes in flow or pressure.
In aqueous systems, the most important element in the water distribution process is the pressure of the water. In many water distribution systems, especially in fire extinguishing systems, the pressure must be adjusted correctly and as a standard. The most basic task of pressure reducing control valves is to reduce the high pressure water included in the system to the required amount of pressure.
Pressure reducing control valve is the most commonly preferred type of valve for adjusting pressure values. These valves have three different positions. In case the pressure reducing valves, which can be used as modulation or closed, are open, the pressure emerging in the inner line activates the diaphragm located in the upper region and water flow is obtained.
If the valve is in the closed position, a pressure is applied towards the diaphragm. As a result of this pressure, the water flow is interrupted and the valve is closed. The modulation position is the position that expresses the basic function of the valve. In this position, the valve makes the diaphragm stable. Therefore, the pressure coming from the inner line and the outer line is equalized and the level of the general pressure in the system reaches the standard level.
The pressure reducing control valve has the function of balancing the existing pressure in any system where water distribution is provided. As in fire extinguishing systems, these valves can also be used in other water installations. It may be necessary to prefer pressure reducing control valves in order to standardize the pressure, especially in water installations with high mains pressure.
The most important effect of pressure reducing control valves is on ensuring the correct pressure efficiency. Although water pressure is the most critical element in water systems, high pressure may not always be desired. In addition, the pressure is always balanced and the system is ready for use, ensuring the highest standard of network efficiency.
The pressure reducing control valve is suitable for use in any network system. It can be used in fire extinguishing systems due to its structure that is not affected by the flow rate. It is also suitable for use in cases where the mains pressure needs to be standardized. It is possible to install pressure reducing control valves in two different ways.
These valves can be mounted in horizontal or vertical position according to the demands. Clockwise movement of the indicator on the valve means that the pressure will be increased. If the indicator moves counterclockwise, it means that the pressure value will be reduced. The most important thing to consider when choosing a pressure reducer is the diameter value of the main line and pressure reducer. The diameters of both components must be equal.
