Radiator valve VS with presetting - corner, 3/4"

Product detailed description

This corner radiator valve with presetting is commonly used in residential and commercial heating systems where precise flow control is required. It is suitable for integration into traditional hydronic systems with steel piping. Installers typically use this valve in applications where pre-set flow rates are necessary for balancing the system. The nickel-plated brass construction ensures durability in environments with fluctuating temperatures and pressures.

The valve is often found in central heating systems, particularly in older buildings with steel pipe infrastructure. It is installed in positions where space is limited, and the corner design allows for directional flexibility in piping layouts. The presetting feature simplifies commissioning by reducing the need for manual adjustments after installation.

Technical parameters

Installation and connection

Installation requires cutting the steel pipe to the correct length and threading the ends to match the valve's 3/4 inch connection. The valve should be positioned so that the flow direction aligns with the system's hydraulic layout. Installers should verify that the pipe threads are clean and free from burrs before tightening the valve in place. A common mistake is over-tightening, which can damage the sealing surfaces or the valve body. It is also important to ensure that the presetting is not disturbed during installation to maintain the intended flow rate.

Compatibility and accessories

This valve is designed for use with steel pipe systems and is compatible with standard steel pipe fittings of 3/4 inch size. To complete the installation, it may be necessary to order additional components such as pipe unions, sealing rings, or pipe cutting tools. No related products are specified for this model.

Technical background for designers

The valve operates by allowing a pre-set flow rate through the radiator, which is determined during manufacturing. The nickel-plated brass body provides good thermal conductivity and resistance to corrosion, making it suitable for long-term use in heating systems. The PN 10 rating ensures that the valve can handle the typical pressures found in low-pressure hydronic systems. The corner design allows for directional flexibility in piping, which is particularly useful in tight spaces or complex layouts. The material properties of CW617N brass ensure that the valve maintains its integrity over time, even when exposed to fluctuating temperatures and water chemistry.

Service and operation

During operation, the valve requires no manual adjustment once the presetting is set. However, it is recommended to periodically inspect the valve for signs of wear or leakage. If a leak is detected, the system should be depressurised and the valve checked for damaged seals or threads. No specific service intervals are provided in the brief.

Frequently asked questions

Can this valve be used with copper pipes?
No, the valve is specifically designed for use with steel pipes and may not be suitable for copper pipe systems without additional fittings.

Is the presetting adjustable after installation?
No, the presetting is factory-set and should not be adjusted after installation to maintain the intended flow rate.

What is the maximum operating temperature of the valve?
The valve is rated for operation at temperatures up to 120°C, as specified in the technical data.

Can this valve be used in a high-pressure system?
No, the valve is rated for PN 10 pressure and should not be used in systems exceeding this pressure rating.
