## Summary description

Thermostatic radiator valve set Perfexim PHA-037 is an axial left-side valve assembly in chrome finish supplied with fittings. Designed for controlling radiator temperature via a thermostatic head (not included), it provides flow regulation and connection to standard heating pipes. Suitable for residential and commercial central heating installations where left-handed axial connection is required.

## Long description

The Perfexim PHA-037 thermostatic radiator valve set is an axial left configuration in a chrome finish supplied with fittings for straightforward installation. It is intended to be used with a separate thermostatic head (not included) to regulate flow to a radiator and control room temperature in central heating systems. The set provides a left-hand connection orientation and is suitable for installations where wall or pipe layout requires axial-left valve alignment.
Advantages
The chrome finish offers corrosion resistance and a surface that is easy to clean, while the axial-left design supports compact piping runs and direct inline connection to radiators. Included fittings simplify assembly and reduce the need to purchase additional connectors. The valve body enables precise flow control when paired with a compatible thermostatic head, contributing to energy-efficient heating regulation.
Suitable for
Residential central heating radiators with left-side axial connection
Commercial or small office radiator installations requiring compact inline valves
Replacement or retrofit projects where existing pipework uses left-handed axial orientation
When it may not be suitable
This valve set requires a compatible thermostatic head which is not included, so it is not a complete thermostat solution out of the box. It is designed for axial left connections; installations that require right-hand, angled (angled/return) or alternative connection types will need a different model.
Key specifications
Valve type: thermostatic radiator valve set, axial left orientation
Finish: chrome
Includes: valve body and fittings for pipe connection
Application: central heating radiator flow control
Connection orientation: left-side inline (axial)
How to use
Mount the valve onto the radiator inlet matching the left axial alignment of the radiator pipework. Fit the supplied fittings to the heating pipes and tighten connections according to standard plumbing practice and local regulations. Attach a compatible thermostatic head to the valve spindle to enable automatic temperature control; set the head to the desired room temperature. After installation, bleed the radiator and check the system for leaks before returning to normal operation.
What to consider before purchase
Confirm that your radiator and pipe layout require an axial left valve orientation.
Ensure you have a compatible thermostatic head (not included) that fits the valve spindle.
Verify pipe diameter and thread type compatibility with the supplied fittings.
Usage recommendations
Use the valve with a thermostatic head from the same compatibility range and follow manufacturer torque and sealing recommendations during installation. Periodically inspect connections for signs of leakage and maintain the chrome surface by cleaning with a mild detergent to preserve appearance and prevent corrosion.
