The Altecnic Eres Lockshield Angled Radiator Valve is designed for installers and homeowners needing precise flow control and easy maintenance for their radiator systems, especially in situations requiring an angled connection. Its key benefit is the integrated drain off facility, simplifying radiator draining for maintenance without needing to shut down the entire heating system. A minor caveat is its manual operation, requiring manual adjustment for temperature control compared to thermostatic valves.

A lockshield valve is used to control the flow of water into a radiator. It allows for radiator balancing, ensuring that heat is distributed evenly throughout your heating system by adjusting the amount of hot water each radiator receives.
The lockshield valve is typically adjusted using a small spanner on the lockshield cap. Turning it clockwise reduces water flow, and counter-clockwise increases it. Adjustments should be made gradually.
The integrated drain-off allows you to drain individual radiators for maintenance, such as flushing or replacing the valve, without needing to drain the entire central heating system. This saves time and water.
While the lockshield valve controls water flow, it is not designed for automatic temperature regulation like a Thermostatic Radiator Valve (TRV). It's primarily for balancing and maintenance.
The Altecnic Eres Lockshield Angled Radiator Valve is available for both 8mm and 10mm pipe sizes.
It's good practice to check and operate the drain-off valve periodically, especially before the heating season, to ensure it's free from blockages and operates smoothly.
An angled valve connects a radiator to pipework where the pipes and radiator connections are at an angle to each other, typically requiring a 90-degree turn. A straight valve is used when the pipework and radiator connections are in line.
Ensure all connections are properly tightened and that appropriate thread sealant or PTFE tape has been used. Check the integrity of the pipe and radiator threads.
Check that the lockshield valve is correctly adjusted. Ensure the drain-off cap is fully closed. If the issue persists, the radiator may require flushing or the system may need balancing.
Gently try to operate the valve. If it remains stiff, apply a small amount of penetrating lubricant to the valve mechanism and try again. Ensure no debris is obstructing the valve.
Ensure the lockshield valve is fully open and the drain-off cap is properly loosened or removed. Check that the hose is securely attached and not kinked. Air may need to be bled from the radiator first.
