Dynamic thermostatic valve - corner, 1/2"

Product detailed description

Dynamic thermostatic valves are essential components in hydronic heating systems where precise flow control and temperature regulation are required. These valves are commonly used in residential and commercial buildings to ensure even heat distribution and efficient system operation. Installers often encounter these valves in systems with radiators, underfloor heating, or panel heaters where individual room temperature control is necessary. The corner configuration of this model allows for directional flexibility in piping layouts, making it suitable for tight spaces or complex installations.

When working with dynamic thermostatic valves, it is important to consider the system’s hydraulic balance and the required flow rates. This model is designed for use in systems operating at up to 120°C and PN 10 pressure, making it suitable for a wide range of heating applications. The pre-set Kv value ensures that the valve can be integrated into a system without requiring on-site flow adjustments, simplifying the installation process for professionals.

Technical parameters

Brand	IVAR

The valve is constructed from nickel-plated brass CW617N, which offers good corrosion resistance and mechanical strength. The operating temperature limit of 120°C and a nominal pressure rating of PN 10 define the conditions under which the valve can be safely used. These parameters are critical for system designers when selecting components that match the operational requirements of the heating system.

Installation and connection

This dynamic thermostatic valve is designed for connection to steel piping and features a 1/2 inch inlet and outlet. The head of the valve is equipped with an M30 x 1.5 thread for attaching a control head or actuator. During installation, it is important to ensure that the valve is aligned correctly and that all connections are tightened to the manufacturer's specifications. Common installation mistakes include incorrect orientation of the valve body or failure to check the sealing surfaces before tightening. To avoid leaks, the installer should inspect the gaskets and ensure that the valve is installed in a position that allows for easy access to the control head for future adjustments.

Compatibility and accessories

The valve is compatible with standard steel piping systems and is intended for use with control heads or actuators that have an M30 x 1.5 thread. No additional accessories are required for basic operation, but installers may need to order control heads separately depending on the system requirements. The valve is not designed for use with alternative media or non-standard piping materials, and any deviations from the manufacturer's specifications should be avoided.

Technical background for designers

The operating principle of this dynamic thermostatic valve is based on the expansion of a temperature-sensitive element inside the valve body. As the temperature of the fluid increases, the element expands, reducing the flow rate to maintain the desired temperature. The nickel-plated brass CW617N construction ensures durability and resistance to corrosion, making it suitable for long-term use in heating systems. The pre-set Kv value allows for predictable flow characteristics, which simplifies system design and reduces the need for manual balancing. The valve’s corner configuration also allows for more compact installations in systems where space is limited.

Service and operation

The valve requires minimal maintenance under normal operating conditions. However, it is recommended to periodically inspect the control head and valve body for signs of wear or corrosion. If the system experiences unusual temperature fluctuations or reduced flow, the valve should be checked for blockages or internal damage. No specific service intervals are provided, but regular visual inspections are advised to ensure continued performance.

Frequently asked questions

Can the valve be used in systems with copper piping?
Although the valve is designed for use with steel piping, it may be compatible with copper piping if the connection method and sealing materials are appropriate. Always refer to the manufacturer’s technical data sheet for confirmation.

Is the Kv value adjustable on site?
The valve has a pre-set Kv value and is not designed for on-site adjustment. If a different flow rate is required, a different model with the appropriate Kv value should be selected.

Can the valve be used with a remote control system?
The valve can be used with a remote control system if the control head or actuator is compatible with the M30 x 1.5 thread and the system’s control protocol.

What is the maximum allowable operating temperature?
The valve is rated for a maximum operating temperature of 120°C. Exceeding this temperature may affect the performance and longevity of the valve.
