Mixing valve - three-way, 1"; Kv 8; 5 Nm
Code: 501550Related products
Product detailed description
This three-way mixing valve is commonly used in central heating systems, underfloor heating loops and hot water circuits to regulate the temperature of the mixed media. It allows the controlled combination of two input flows into one output, ensuring stable and accurate temperature delivery. The valve is typically installed in systems where thermal comfort and energy efficiency are critical, such as in residential, commercial and industrial buildings. The design supports integration with automatic control systems and servomotors for remote or automated adjustment.
The installation process involves connecting the valve to the primary and secondary circuits using standard pipe connections. Careful alignment of the flow direction is essential to ensure correct operation. The valve is often part of a larger system including pumps, expansion vessels and temperature sensors. It is important to verify the compatibility of the control system and servomotor torque to avoid mechanical stress during operation.

The valve is rated for a maximum operating temperature of 120°C, making it suitable for high-temperature heating applications. The nominal pressure rating of PN 10 indicates the valve can handle up to 10 bar of pressure at standard conditions. The servomotor requires a torque of 5 Nm, which must be matched with compatible actuators to prevent overloading. These parameters are essential for determining the suitability of the valve in specific system designs and for selecting appropriate control components.
Installation and connection
The valve connects via 1-inch threaded ports, compatible with standard piping systems in heating and plumbing applications. Before installation, ensure that the flow direction is correctly aligned with the arrow markings on the valve body. The tightening torque for the connections should follow standard guidelines for brass fittings to avoid leakage or damage. A common mistake during installation is neglecting to align the flow direction, which can lead to inefficient mixing or system imbalance. Always verify the orientation and secure all connections properly.
Compatibility and accessories
This mixing valve is designed to work with servomotors and control systems that provide a torque output of at least 5 Nm. It is compatible with standard heating system components such as circulator pumps and temperature controllers. For complete system functionality, additional components such as temperature sensors and control valves may need to be specified separately. The valve is suitable for use in both open and closed-loop systems, provided the media and operating conditions match the valve’s specifications.
Technical background for designers
The operating principle of the three-way mixing valve is based on balancing the flow of two incoming media streams to produce a consistent output temperature. The valve body is made of CW617N brass, a material known for its corrosion resistance and durability in hot water and steam environments. The PN 10 pressure rating ensures the valve can operate reliably under standard heating system pressures. Long-term performance depends on maintaining clean media and avoiding excessive thermal cycling, which can affect the internal components and sealing surfaces.
Service and operation
Regular inspection of the valve includes checking for signs of leakage around the connections and verifying the smooth operation of the actuator. The internal components should remain free from debris and scale buildup to maintain accurate mixing performance. No scheduled service intervals are specified, but it is recommended to inspect the valve periodically during routine system maintenance. If the valve shows signs of reduced responsiveness or uneven flow distribution, disassembly and cleaning may be necessary.
Frequently asked questions
Can the valve be used with a servomotor that provides less than 5 Nm of torque?
No, the servomotor must provide at least 5 Nm of torque to ensure proper operation of the valve. Using a weaker motor could result in incomplete actuation or mechanical failure.
Is the valve suitable for use in a steam heating system?
Yes, provided the steam temperature does not exceed 120°C and the system pressure remains within the PN 10 rating. The CW617N brass body is resistant to corrosion from steam condensate.
Can the valve be installed in a vertical position?
Yes, the valve can be mounted in any orientation as long as the flow direction is respected and all connections are properly sealed.
What is the maximum allowable temperature for the media passing through the valve?
The maximum operating temperature is 120°C, beyond which the valve may suffer material degradation or seal failure.
