Drayton RT212 RT313 RT414 TRV4 Two Pipe Specification

The Drayton RT212, RT313, RT414, and TRV4 are thermostatic radiator valves designed for efficient temperature control in residential and commercial heating systems. These valves are engineered to optimize energy use by automatically adjusting the flow of hot water into radiators, maintaining a consistent room temperature.

The RT212 model is a standard thermostatic valve, offering reliable performance with a simple design. It features a robust wax sensor for accurate temperature regulation and is suitable for standard heating applications. The RT313 variant builds upon this functionality with enhanced precision, utilizing a liquid sensor for faster response times to temperature changes, making it ideal for environments requiring quick adjustments.

The RT414 model introduces additional user-friendly features, including a bi-directional flow capability, allowing for flexible installation on either the supply or return side of a radiator. This model also supports a wider range of temperature settings, providing greater control over the heating environment.

The TRV4 is the premium offering in this series, incorporating advanced features such as frost protection, which prevents the radiator from freezing in cold conditions. It is equipped with a highly sensitive liquid sensor that ensures rapid and precise temperature adjustments. The TRV4 is known for its durability and reliability, making it suitable for high-demand applications and environments where maintaining a consistent climate is critical.

All models in this range are designed for two-pipe heating systems and are compatible with a wide variety of radiator types. They are easy to install and adjust, featuring an intuitive interface for setting the desired temperature. The Drayton series is engineered to enhance heating efficiency, reduce energy consumption, and provide comfortable living and working spaces.

Drayton RT212 RT313 RT414 TRV4 Two Pipe F.A.Q.

How do I install the Drayton TRV4 on a radiator?

To install the Drayton TRV4, turn off your heating system and drain the radiator. Remove the old valve, clean the threads, and attach the TRV4 to the radiator inlet, ensuring a tight seal. Follow the included instructions for valve orientation and setting.

What should I do if my Drayton RT212 valve is not heating properly?

First, check if the valve is set to the correct temperature. If it's still not heating, ensure there is no trapped air in the radiator and bleed it if necessary. Finally, verify the valve is not stuck and the pin moves freely.

How can I calibrate the temperature settings on a Drayton RT313?

To calibrate your Drayton RT313, compare the room temperature with a reliable thermometer. Adjust the valve settings incrementally, allowing time for each change to stabilize before making further adjustments.

Why is my Drayton TRV4 making a clicking noise?

The clicking noise may be due to thermal expansion or contraction. Ensure the valve is securely attached and that there is no debris inside. If the noise persists, consult the manual or customer support.

Can I use Drayton RT414 valves with underfloor heating systems?

Drayton RT414 valves are designed for radiator systems and are not typically used with underfloor heating. It's best to use controls specifically designed for underfloor systems.

What maintenance is required for Drayton TRV4 valves?

Regularly check for leaks and ensure the valve is free from dust and debris. Annually, clean the valve and ensure the pin moves freely by gently pressing it in and out.

How do I prevent my Drayton RT212 from sticking?

To prevent sticking, periodically rotate the valve head from the maximum to the minimum setting. This helps keep the internal mechanism moving freely.

What is the ideal temperature setting for a Drayton RT313 in a living room?

The ideal setting varies, but generally, 20-22°C (68-72°F) is comfortable for a living room. Adjust based on personal preference and external temperature conditions.

How can I identify if the Drayton RT414 is faulty?

If the radiator remains cold when others are warm, or if the valve does not respond to temperature adjustments, the RT414 may be faulty. Inspect for physical damage and ensure the pin is not stuck.

What are the differences between the Drayton RT212 and TRV4 valves?

The RT212 is a basic thermostatic valve, while the TRV4 offers more precise temperature control and advanced features like frost protection. The TRV4 is generally more suited for high-performance heating systems.
