Thermostatic double control valve - corner, 1/2" x EK

Product detailed description

Thermostatic double control valves are essential components in hydronic heating systems, particularly in residential and commercial buildings where precise temperature regulation is required. These valves are commonly installed in radiator circuits to control the flow of heated water based on the ambient temperature. Installers working on central heating systems will encounter these valves in both new builds and renovation projects, where they are integrated with thermostatic radiator heads and central heating controllers.

Correct selection and installation of these valves is crucial for system efficiency. The valve must match the system’s hydraulic requirements and be compatible with the piping material and fittings. The corner design of this model allows for flexible installation in tight spaces, such as under radiators or in wall-mounted configurations. The adjustable Kv value ensures that the valve can be fine-tuned to the specific heat output of the radiator and the building’s thermal load.

Technical parameters

Installation and connection

This corner valve is designed for 1/2 inch pipe connections and features a M30 x 1.5 thread for the valve head. It can be connected to copper or plastic pipes using IVAR compression fittings (TR for copper, TA for Alpex, TP for plastic). During installation, it is important to ensure that the compression fittings are properly seated and tightened according to the manufacturer’s instructions. A common mistake is over-tightening, which can damage the sealing components and lead to leaks. The valve should be installed in a position that allows for easy access to the head for adjustment and maintenance.

Compatibility and accessories

The valve is compatible with standard thermostatic radiator heads that feature a M30 x 1.5 thread. For installation, IVAR compression fittings must be ordered separately, depending on the type of pipe material used. These include IVAR.TR for copper, IVAR.TA for Alpex, and IVAR.TP for plastic pipes. The valve is not supplied with fittings or the thermostatic head, so these components must be selected and ordered based on the system requirements and the type of radiator being used.

Technical background for designers

This thermostatic double control valve operates by adjusting the flow of hot water in response to the temperature sensed by the thermostatic head. The nickel-plated brass body (CW617N) offers good mechanical strength and resistance to corrosion in water-based heating systems. The valve’s corner design allows for directional flexibility in the piping layout. The adjustable Kv value is a key factor in system design, as it determines the maximum flow capacity and must be matched to the radiator’s heat output and the building’s thermal requirements. The valve integrates into the system via standard compression fittings, ensuring a secure and leak-free connection.

Service and operation

Regular inspection of the valve and its connections is recommended to ensure continued performance. Check for signs of leakage around the compression fittings and ensure that the thermostatic head is functioning correctly. If the valve is not operating as expected, it may be necessary to recalibrate the Kv value or replace the head. No specific service intervals are provided, but maintenance should be carried out as part of routine system checks.
