Please Note: Only the EPDM Seat Is WRAS Approved – Not the Entire Valve
The TTV Stainless Steel Wafer Butterfly Valves are designed for reliable flow control across a variety of applications, offering excellent corrosion resistance and durability thanks to their high-quality stainless steel construction. These valves are fitted with an EPDM seat that is WRAS approved, making them suitable for potable water applications where compliance at the material level is important. However, it's essential to understand that while the EPDM seat carries WRAS certification, the complete valve assembly does not.
Ideal for general industrial use, water distribution systems, and light chemical processing, the TTV Wafer Butterfly Valve’s lightweight design ensures easy installation between flanges, while its streamlined body reduces pressure loss. With a low torque requirement and bubble-tight shut-off, this valve is both efficient and cost-effective when paired with manual, electric, or pneumatic actuation.
Key Features:
🔒 WRAS Approved EPDM Seat – Ensures safe use with potable water where material compliance is critical
🛠️ Stainless Steel Body & Disc – Corrosion-resistant and built for longevity in demanding conditions
⚙️ Wafer Pattern Design – Easy to install between PN10/16 or ANSI 150 flanges

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.
