Radiator valve VS with presetting - corner, 3/8"

Product detailed description

This corner-mounted radiator valve is commonly used in residential and commercial heating applications where space constraints require angular connections. It provides a fixed flow rate setting, suitable for systems where individual room balancing is not required. The valve is often installed in compact spaces such as under windows or in narrow wall cavities, where a straight-line connection is impractical.

Typical installations include panel radiators, baseboard heaters and convector units in single- and multi-family buildings. The valve integrates into traditional hydronic heating systems and can be used with thermostatic radiator valves or manual controls depending on system design. Installers should ensure that the valve is correctly aligned with the pipe direction and that the presetting matches the intended flow rate for the circuit.

Technical parameters

The nominal pressure rating of PN 10 indicates suitability for low-pressure heating circuits, typically found in domestic and light commercial systems. The nickel-plated brass CW617N material provides corrosion resistance and durability in hot water environments up to 120°C. These parameters are essential for ensuring correct valve selection based on system pressure and temperature conditions.

Installation and connection

The valve is designed for connection to steel piping using 3/8 inch threaded ports. Prior to installation, confirm that the pipe threads are clean and free of debris. Apply a suitable sealing compound or PTFE tape to the male threads to prevent leaks. Ensure that the valve orientation allows for a secure and leak-free fit. A common mistake during installation is incorrect angular positioning, which can cause stress on the valve body and lead to premature failure.

Verify that the valve is compatible with the pipe material and that the system pressure does not exceed PN 10. Avoid overtightening the connections, which can damage the internal components. After installation, perform a visual and pressure test to confirm the integrity of the connection.

Compatibility and accessories

This valve is compatible with standard steel pipe systems and can be used in conjunction with thermostatic radiator valves for zoned control. To complete a full radiator circuit, additional components such as a lockshield valve or a manual control valve may be required. For systems requiring individual room balancing, a separate balancing valve should be installed upstream of this unit.

Technical background for designers

The valve operates via a fixed orifice that restricts flow to a predetermined level. This makes it ideal for circuits where flow rates are not subject to frequent adjustment. The CW617N brass alloy is known for its high tensile strength and resistance to dezincification, making it suitable for long-term use in hot water systems. The nickel plating further enhances corrosion resistance, particularly in environments with aggressive water chemistry.

Proper integration into the system requires matching the valve’s preset flow rate with the design load of the radiator. Overloading the valve beyond its capacity can lead to insufficient heat output or excessive pressure drop.

Service and operation

Regular inspection of the valve for signs of leakage or corrosion is recommended. In case of suspected blockage or reduced performance, disassemble the valve and clean the internal components according to the manufacturer’s guidelines. No scheduled service intervals are specified in the technical documentation. Any maintenance should be carried out by qualified personnel using appropriate tools to avoid damage to the valve body or sealing surfaces.

Frequently asked questions

Can this valve be used with copper piping?
Yes, provided that the copper piping is compatible with the valve’s 3/8 inch threaded connection. Ensure that the connection is sealed properly to prevent leaks.

Is this valve suitable for use with a thermostatic radiator valve?
Yes, the valve can be used in series with a thermostatic radiator valve. However, the fixed flow rate of this valve may limit the range of temperature control achievable with the thermostat.

Can the preset flow rate be adjusted after installation?
No, the valve is factory preset and cannot be adjusted in the field. Any changes to the flow rate require replacing the valve with one of a different preset setting.

What is the maximum operating temperature for this valve?
The valve is rated for a maximum temperature of 120°C. Exceeding this limit may affect the integrity of the internal components and the sealing surfaces.
