## Summary description

Thermostatic radiator valve RED, model 90381581521, angled (corner) design in chrome finish with right-handed connection. Connection sizes are 1/2" and 3/4". Intended for controlling flow and temperature on radiators, it fits typical plumbing installations requiring a right-angle, right-handed valve for balancing and regulating heat output.

## Long description

Thermostatic radiator valve RED 1/2" x 3/4" angled chrome right-handed, model 90381581521 is an angled control valve designed for regulating flow and temperature on radiators. The chrome finish and right-handed connection suit installations where the pipework enters at a right angle and requires a valve that allows precise balancing of heat output. Connection sizes are 1/2" and 3/4", making the valve compatible with common radiator and pipe fittings in central heating systems.
Advantages
The angled design provides compact installation near walls and radiator panels while the thermostatic function enables automatic control of radiator temperature according to the selected setpoint. A chrome surface offers corrosion resistance and a clean appearance that integrates with most plumbing and interior finishes. The right-handed connection ensures proper alignment and leak-free mating with compatible fittings when piping layout requires asymmetrical orientation.
Suitable for
 Domestic and commercial radiators with right-angle inlet geometry
 Central heating systems requiring thermostatic temperature regulation
 Retrofit projects where a chrome-finish angled valve is needed for aesthetic or space reasons
 Systems that need flow balancing between multiple radiator circuits
Key specifications
 Valve type: Thermostatic angled radiator valve
 Connection orientation: Right-handed (angled/right-angle)
 Connection sizes: 1/2" and 3/4"
 Finish: Chrome-plated surface
 Application: Closed hot-water central heating radiators
How to use
Install the valve in accordance with plumbing best practices, ensuring the right-handed orientation matches the radiator inlet and supply pipe layout. After secure mechanical connection and pressure testing of the system, attach a compatible thermostatic head (if not pre-fitted) and set the desired room temperature using the head’s scale. The valve modulates flow automatically to maintain the selected setpoint; periodic checks for leaks and correct operation are recommended after commissioning.
Usage recommendations
Use the valve in systems with appropriate water quality and operating pressures for radiator components. When replacing an existing valve, verify thread types and dimensions before installation. For reliable temperature control, pair the valve with a properly calibrated thermostatic head and, where necessary, bleed the radiator to remove trapped air after installation.
