About RAW Thermostatic Valve
MAIN CHARACTERISTICS AND USES : The RAW thermostatic mixing valves are used in hot water systems for sanitary use. They keep the temperature of the mixed water supplied to the user constant even when the condition listed below it - Temperature
- Supply pressure
- Incoming hot and clod water flow
The RAW thermostatic valves have a temperature range that is ideal for heating a centralized water system with heater. |
| OPERATION : The valves were designed to supply domestic hot water at an adjustable and constant temperature where no other regulating system is present. The very sensitive thermostatic element is positioned centrally inside the outgoing stream union and it guides a regulating shutter which adjusts the incoming cold water flow (C fig.2) to the hot water flow (H fig.2) according to the mixed water temperature (MIX fig.2) . The knob can be used to regulate the temperature of the outgoing water. There Is also a hot water locking system in case the supply of cold water is stopped (anti- scald system) |

FAQs of RAW Thermostatic Valve:
Q: How do I determine the appropriate size of RAW Thermostatic Valve for my system?
A: To select the correct size, consider the systems flow rate and connection requirements. The valve is available in DN15, DN20, and DN25 with compatible port sizes of 1/2 inch, 3/4 inch, and 1 inch to match your piping. Flow rates reach up to 60 L/min depending on the valve size.
Q: What installation positions are possible for this thermostatic valve?
A: This valve can be mounted both horizontally and vertically, giving flexibility during installation across commercial, residential, or industrial systems. Ensure the connection type matches your application, as the valve supports threaded (BSP/NPT) fittings.
Q: When is it recommended to use the thermal actuator version of the valve?
A: The thermal actuator version is ideal for automated temperature control or when remote adjustments are needed. Choose the actuator model for setups requiring electrical actuation, available in 220V or 24V, which is common in advanced HVAC and underfloor heating systems.
Q: Where can this valve be installed for optimal performance?
A: This thermostatic valve is suitable for hot water, steam systems, HVAC networks, and underfloor heating. It is designed for commercial, residential, and industrial settings, offering precise thermal regulation across various piping networks.
Q: What is the process for replacing the thermostatic cartridge inside the valve?
A: To replace the thermostatic cartridge, first depressurize and cool the valve. Then, unfasten the cartridge housing, remove the old cartridge, and install the new one according to the manufacturers instructions. This design feature minimizes downtime and simplifies maintenance.
Q: How does using this thermostatic valve benefit my heating or cooling system?
A: By maintaining stable water or steam temperatures (with an accuracy of 2C), this valve increases energy efficiency and protects against temperature fluctuations. Its reliable control system prevents scalding and extends equipment lifespan, offering a safer and more comfortable environment.
