Thermostatic Radiator Valve Set Perfexim PHA-037 axial left chrome with fittings (MPN 20-037-0000-000)

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.
