Radiator valve VS - corner, 3/8"

Product detailed description

This corner-mounted radiator valve provides reliable flow control in residential and commercial heating installations. The compact design suits tight spaces in underfloor heating layouts or where pipework changes direction between radiators and distribution manifolds. Installers commonly use it in systems with steel pipe connections requiring precise manual regulation of heat output.

The nickel-plated brass body resists corrosion from water and antifreeze mixtures. The internal sealing mechanism ensures consistent throttling performance over time, even with frequent adjustments during commissioning or seasonal balancing. This valve requires no power supply and operates purely through manual adjustment using a standard radiator key.

Technical parameters

The nominal pressure rating of PN 10 indicates suitability for standard central heating circuits with moderate pressure levels. The CW617N brass alloy provides sufficient strength for long-term operation while maintaining compatibility with soldered steel pipe joints. These parameters guide proper sizing when replacing existing valves or extending heating networks.

Installation and connection

Installers should clean the threaded ends of connecting pipes before screwing the valve into position. The 3/8 inch female thread accepts standard steel pipe fittings with male BSP threads. Use PTFE tape or anaerobic sealant to prevent leaks at the joint. Verify alignment with adjacent components before tightening the connection fully.

Common errors include overtightening which can damage the sealing surface or using incompatible thread types. Ensure the valve orientation allows for easy access to the adjusting stem after installation. Check for free movement of the valve stem before final tightening to avoid binding issues that could affect modulation accuracy.

Compatibility and accessories

This valve works with standard steel pipe systems using BSP thread connections. For complete system functionality, installers should pair it with compatible radiator valves and balancing tools. Additional components such as lock nuts and sealing compounds may be required depending on local installation standards and pipe preparation methods.

Technical background for designers

The valve controls water flow manually through a tapered seat and conical closing disc. The nickel-plated brass body offers good thermal conductivity and resistance to dezincification. When integrated into a heating circuit, the valve's response to manual adjustments depends on the system's overall hydraulic balance and the presence of thermostatic heads if fitted.

Long-term performance is influenced by water quality parameters such as pH and hardness. Regular exposure to temperatures near the maximum rated value can accelerate wear of the sealing surfaces. Proper initial balancing of the system helps maintain efficiency and extends the service life of all components including this valve.

Service and operation

Periodic inspection of the valve's sealing integrity is recommended during routine system checks. Look for signs of leakage at the thread joints and ensure the adjusting stem moves smoothly without resistance. Clean the exposed external parts if contamination occurs from suspended solids in the heating medium. No scheduled servicing intervals are specified for this component according to manufacturer documentation.

Frequently asked questions

Can this valve be used with copper pipe connections?
Yes, provided the copper fittings have compatible BSP threading and proper sealing compounds are applied during installation.

Is this valve suitable for use in high-rise buildings?
It functions within standard pressure ranges typical of multi-storey heating systems, but not for high-pressure industrial applications.

Can this valve be used with thermostatic radiator heads?
Yes, it serves as a base valve for thermostatic heads when additional manual control is required for balancing purposes.

What tools are needed for installation?
A standard spanner for tightening and a radiator key for stem adjustment are sufficient for basic installation and commissioning tasks.
