Radiator valve VD - straight, 1/2"

Product detailed description

This straight radiator valve is commonly used in residential and commercial buildings where steel pipe systems are employed. It is typically installed in central heating systems to regulate the flow of heated water to individual radiators. The valve is designed for use in systems where precise flow control and reliable sealing are required. Installers working on traditional heating systems will find this valve suitable for applications where a direct, linear connection is needed between the radiator and the supply pipe.

Given the nominal pressure rating and temperature limit, this valve is appropriate for standard central heating systems operating within typical domestic and light commercial parameters. The nickel-plated brass construction ensures durability and resistance to corrosion, making it suitable for long-term use in wet environments. The valve is intended for use with steel pipe systems, which are common in older and traditional installations across Europe.

Technical parameters

Material	Nickel-plated brass CW617N
Nominal pressure	PN 10
Weight	0.204 kg
Code	501452
Brand	IVAR

The nominal pressure rating of PN 10 indicates that the valve is suitable for systems operating at up to 10 bar pressure. The maximum operating temperature of +120°C means it can handle typical heating system temperatures. These parameters are essential for ensuring the valve is correctly sized and selected for the system's operating conditions. The material specification (nickel-plated brass CW617N) also plays a role in determining its suitability for specific applications, particularly in systems with steel piping.Installation and connection The valve is designed for direct connection to steel pipes using a 1/2 inch thread. Installers should ensure that the pipe threads are clean and free from debris before installation. A sealing compound or thread tape should be applied to the male thread to prevent leaks. The valve should be tightened evenly using a suitable wrench to avoid damaging the threads or the valve body. Common installation mistakes include over-tightening, which can cause thread damage, and using incompatible sealing materials that may degrade over time. It is important to verify that the valve is fully open before testing the system to prevent pressure build-up.Compatibility and accessories This valve is compatible with standard steel pipe systems and is intended for use with conventional radiators. It is typically used in conjunction with a thermostatic radiator valve or a manual control valve to regulate flow. No additional accessories are required for basic installation, but sealing compounds or thread tape should be available for use during fitting. As this is a single-valve model, it is not designed for use with two-port systems that require a separate on/off and flow control valve.Technical background for designers The valve operates as a linear flow control device, allowing the installer to adjust the flow of hot water to the radiator. The nickel-plated brass CW617N material provides good resistance to corrosion and ensures long-term durability in wet environments. The valve's design allows for a direct connection to steel pipes, making it suitable for traditional heating systems. The service life and efficiency of the valve are influenced by the quality of the installation, the cleanliness of the system, and the absence of debris in the water supply. Regular maintenance and inspection can help ensure continued performance.Service and operation Routine inspection of the valve should include checking for leaks at the connection points and ensuring that the valve operates smoothly without resistance. If the system is known to contain debris or particulate matter, it is advisable to install a filter upstream of the valve to prevent blockages. No specific service intervals are provided, but it is recommended to inspect the valve periodically during system maintenance. If the valve shows signs of wear or leakage, it should be replaced to maintain system efficiency and prevent water loss.Frequently asked questions

Can the IVAR VD 201 be connected to copper pipes?
It is not recommended to connect this valve to copper pipes, as it is specifically designed for use with steel pipe systems. The sealing and thread compatibility are optimised for steel pipe connections.

Is the valve suitable for use in high-temperature systems?
The maximum operating temperature is +120°C, which makes it suitable for standard central heating systems. It should not be used in systems operating above this temperature.

Can the valve be used in a two-port system?
This is a single-valve model and is not designed for use in two-port systems that require separate on/off and flow control functions. It is intended for use with a separate thermostatic or manual control valve.

What is the recommended sealing material for installation?
A sealing compound or thread tape is recommended for use with the 1/2 inch thread. It is important to ensure that the sealing material is compatible with the system's operating conditions and does not degrade over time.
