## Summary description

Comap angle return valve model 428704 is a 1/2" return (radiator) valve with an M22 connection designed for heating systems. The valve provides angled connection between radiator and pipework, enabling flow regulation and closure when servicing. Suitable for domestic and commercial radiators where compact angled installation and a standard M22 fitting are required.

## Long description

Comap angle return valve 1/2" with M22 connection is designed for use in heating systems where an angled connection between the radiator and pipework is required. The compact valve body allows installation in confined spaces close to walls or brackets and provides shut-off and flow regulation for radiator circuits. It is manufactured for compatibility with standard M22 fittings and is intended for both domestic and commercial radiator installations that require a reliable return (radiator) valve.
Advantages
The angle return valve offers a compact angular design that saves installation space and positions the pipework neatly. It provides manual flow regulation and a positive shut-off for maintenance without draining down the whole system. The valve is made to fit M22 industry-standard connections, ensuring compatibility with many radiator tails and fittings. Its construction supports routine operation in central heating systems and helps reduce the need for custom adaptors.
Suitable for
Domestic radiators with limited clearance behind the unit
Commercial heating installations requiring compact angled returns
Replacement of existing M22-connected return valves
Situations requiring shut-off for radiator maintenance or balancing
Key specifications
Connection type: angled return (radiator) valve
Nominal pipe connection size: 1/2"
Fitting thread standard: M22 connection interface
Functionality: manual flow regulation and shut-off

How to use
Shut off the heating system or isolate the radiator circuit according to local safety procedures before installation or maintenance. Fit the valve to the radiator tail and corresponding pipework using the M22 connection, ensuring proper sealing with the correct gasket or sealing material as specified for the radiator manufacturer. Use the valve spindle or cap to set the desired flow rate or to fully close the circuit during service. After fitting, bleed the radiator to remove trapped air and check for leaks at all joints.
Usage recommendations
Use this valve in systems operating within standard central heating temperature and pressure ranges and avoid exposure to corrosive fluids. During installation, verify thread compatibility and use appropriate sealing materials. For balancing or precise flow control, combine the valve with a measuring or balancing device and follow relevant hydraulic balancing procedures.
