## Summary description

## Long description

Straight radiator valve Valvex VECTOR 1/2" model 4420080 is a mechanical inline valve designed for connection to 1/2-inch radiator fittings in hot water heating systems. Manufactured by Valvex, this valve provides a simple and durable solution for isolating and controlling coolant flow to domestic or commercial radiators. The straight body and standard thread size make it compatible with typical radiator inlet fittings and allow straightforward replacement or installation during maintenance and balancing of heating circuits.
Advantages
The Valvex VECTOR straight valve features a robust mechanical design that ensures reliable operation and long service life in central heating systems. Its straight configuration reduces installation complexity when paired with corresponding radiator fittings and allows tight shut-off when isolating a radiator. The valve construction is suited for repeated use during installation and adjustment of heating circuits without significant performance degradation.
Suitable for
Domestic hot water radiators with 1/2" inlet connections
Commercial radiator installations requiring straightforward isolation or flow control
Maintenance and balancing of heating circuits
Replacement of existing straight radiator valves
Key specifications
Connection size: 1/2" standard radiator thread
Configuration: straight (inline) valve body
Function: mechanical flow control and isolation
Application medium: hot water for central heating systems
Typical installation location: radiator inlet
How to use
Install the valve inline at the radiator inlet, ensuring compatible 1/2" threads on both the valve and radiator fitting. Use appropriate sealing (such as PTFE tape or approved joint sealant) on threaded connections and tighten to manufacturer-recommended torque to avoid leaks while preventing damage to threads. Operate the valve spindle to open or close flow as needed during installation, maintenance, or balancing of the heating system. When isolating a radiator, fully close the valve; for balancing, adjust to achieve the desired flow rate and radiator temperature.
Usage recommendations
Use the valve with water-based central heating systems and avoid exposure to incompatible fluids. During installation, confirm thread compatibility and check for leaks at operating temperature. For extended service life, operate the valve periodically and inspect during routine heating-system maintenance.
