Product Overview
Keeping your water systems safe and compliant doesn't have to be a headache. This bit of kit, the KWC DVS Thermal Disinfection Valve (TDV), is a brilliantly simple solution designed to make a critical job much easier.

Case Study: Real Business, Real Results
The Elmbridge Community Centre in Sheffield needed a more efficient way to manage their water safety protocols for their public showers and kitchenettes. Their old system was time-consuming and made logging compliance checks a chore.
"Installing the KWC DVS valves has been brilliant. Our caretaker can now complete the weekly flushing routine in a fraction of the time. It's simple, reliable, and gives us a clear, auditable trail for our health and safety records. A solid piece of engineering."
Robert Green – Facilities Manager
The upgrade reduced the time spent on thermal disinfection tasks by over 60%, allowing staff to focus on other important maintenance duties.
Installation and Maintenance Guide
Setting It Up
- Installation must be carried out by a qualified and competent plumber.
- Ensure the water system is isolated and fully drained before fitting the valve.
- Always install according to the flow direction arrows indicated on the valve body.
- Check for a smooth quarter-turn action and ensure no leaks after re-pressurising the system.
Keeping It Going
- Operate the valve as part of your scheduled Legionella control risk assessment (e.g., quarterly or monthly).
- Log every disinfection cycle for your compliance records.
- Periodically check the valve for any signs of leaks or damage, especially after operation.
- Clean the exterior with a soft cloth; avoid using abrasive chemicals that could damage the brass.
Frequently Asked Questions
Q: What is a thermal disinfection valve used for?
A: It's used to safely and easily flush a water system's outlets (like taps and showers) with scalding hot water to kill bacteria, such as Legionella.
Q: Can I install this valve myself?
A: No. Installation should always be carried out by a qualified, competent plumber to ensure it complies with water regulations.
Q: Why is WRAS Approval so important?
A: WRAS (Water Regulations Advisory Scheme) Approval shows that a product meets the high standards set by UK water regulations, ensuring it's legal and won't contaminate the water supply.
Q: What does DZR Brass mean?
A: DZR stands for Dezincification Resistant. It's a type of brass alloy that is highly resistant to corrosion, making it perfect for long-term use in plumbing systems.
Q: How often do I need to use the valve?
A: The frequency depends on your site's specific Legionella risk assessment, but it's typically operated on a monthly or quarterly basis as part of a regular maintenance schedule.
Q: Does this valve replace my existing thermostatic mixing valve (TMV)?
A: No, it is installed alongside your TMV. Its purpose is to temporarily bypass the TMV during the disinfection process only.
Q: Is this suitable for a drinking water supply?
A: Yes, as it is WRAS approved, it is certified as safe for use in potable (drinking) water systems.
Q: What's the purpose of the non-return valves?
A: They prevent water from flowing backward through the valve, which is a critical safety feature to stop cross-contamination between hot and cold supplies.

Explore more from KWC DVSHow Thermal Disinfection Keeps Your Water Safe
Ever wondered how a simple valve can fight off nasty bacteria like Legionella? Think of your hot water pipes like a garden. In lukewarm water (20-45°C), bacteria can grow like weeds. A thermal disinfection valve is your go-to tool for 'weeding' the system. It acts as a temporary bypass, allowing you to shut off the cold water feed to a tap or shower and flush it with water that's over 60°C. This scalding heat effectively kills off the bacteria that have built up in the pipework and outlet. This valve makes that process safe and incredibly simple, ensuring you can regularly and easily maintain a healthy water system without any fuss.
