Please Note: Only the EPDM Seat Is WRAS Approved – Not the Entire Valve
The TTV Ductile Iron Wafer Butterfly Valves with Aluminium Bronze Disc offer a durable and corrosion-resistant solution for demanding flow control applications. Designed with a robust ductile iron body and a high-performance aluminium bronze disc, these valves are well-suited for water, HVAC, and general industrial use. The inclusion of a WRAS-approved EPDM seat provides material compliance for use with potable water, but the full valve is not WRAS certified.
The aluminium bronze disc enhances resistance to wear and corrosion, making this valve ideal for more aggressive environments or systems requiring additional material strength. Easy to install between standard PN10/16 or ANSI 150 flanges, the wafer pattern body ensures a compact fit while delivering reliable, bubble-tight shut-off.
Key Features:
✅ WRAS Approved EPDM Seat – Suitable for potable water applications where seat compliance is critical
🧱 Ductile Iron Body – Strong, durable, and built to withstand mechanical stress
🛡️ Aluminium Bronze Disc – Corrosion-resistant and ideal for harsher environments
⚙️ Wafer Pattern Design – Installs quickly between flanges without taking up space
🔧 ISO 5211 Mounting Pad – Direct mounting for electric or pneumatic actuators
💨 Low Torque Requirement – Smooth operation for both manual and automated use
🧰 Service-Friendly Design – Replaceable components for extended valve life
This valve combines strength, corrosion resistance, and water-safe sealing — making it a go-to choice for systems needing high performance without full WRAS valve certification.

FAQs
What is a WRAS-approved valve?
A WRAS-approved valve is a valve that has been certified by the Water Regulations Advisory Scheme in the UK. This certification ensures that the valve complies with the strict standards for materials and construction, making it safe for use with potable water systems.
Why is WRAS approval important for valves?
WRAS approval is important because it signifies that the valve will not cause water contamination or pose a health risk when used. This is crucial for maintaining the safety and quality of drinking water.
How can I identify a WRAS-approved valve?
WRAS-approved valves are typically marked with the WRAS logo and a unique approval number. These identifiers can usually be found on the body or packaging of the valve.
What types of valves can be WRAS approved?
Any valve intended for use with potable water can be WRAS approved. Common types include ball valves, check valves, gate valves, and pressure reducing valves.
Where are WRAS-approved valves typically used?
WRAS-approved valves are used in residential, commercial, and industrial water systems where there is direct contact with drinking water. They are essential in systems requiring high standards of hygiene and safety.
Are WRAS-approved valves required by law?
In the UK, water fittings that come into contact with the public water supply must comply with the Water Supply (Water Fittings) Regulations or Scottish Byelaws. These require that components such as valves do not contaminate water and are of an appropriate quality, often necessitating WRAS approval.
What are the benefits of installing WRAS-approved valves?
Installing WRAS-approved valves helps ensure compliance with water safety regulations, prevents water contamination, and enhances the reliability and longevity of water supply systems.
How do I install a WRAS-approved valve?
Installation of a WRAS-approved valve should follow manufacturer guidelines and local plumbing codes. It's recommended to hire a qualified plumber to ensure proper installation and operation.
