🛠️ Tips for selecting the right ball valve for your application
🛡️ Avoid compliance issues with the correct certified product
When it comes to potable water systems, choosing the right WRAS approved ball valve is crucial. Whether you’re working on a domestic installation or a large-scale commercial project, selecting the correct valve ensures water safety, regulatory compliance, and long-term system performance.
At Wrasvalves.com, we supply a wide range of WRAS certified ball valves suitable for drinking water applications – but how do you know which one is right for your job? Let’s break it down.
💡 Why WRAS Approval Matters for Ball Valves
WRAS (Water Regulations Approval Scheme) approval certifies that a valve is safe to use in systems that carry drinking water. It ensures the materials won't leach contaminants, corrode, or degrade over time, keeping the water safe for human consumption.
Without WRAS certification, you risk non-compliance with the UK Water Supply (Water Fittings) Regulations – which can lead to failed inspections, legal issues, and unsafe installations.
⚙️ Key Factors to Consider When Choosing a WRAS Ball Valve
1. Material Compatibility
Choose a material suitable for potable water.
Brass (nickel-plated) – Common, cost-effective, corrosion-resistant
Stainless Steel – Excellent durability and hygiene, ideal for high-spec applications
Plastic (PVC or ABS) – Lightweight, non-metallic option for low-pressure systems
2. Valve Size & Flow Requirements
Make sure the valve matches your system’s pipework (e.g. 15mm, 22mm, 1", 2", etc.) and is sized to handle the desired flow rate without causing pressure drop.
3. Pressure & Temperature Ratings
Check that the valve’s pressure and temperature limits align with your system. WRAS approved valves will typically list their max pressure (PN rating) and working temperature range.
4. End Connections
Match the connection type to your existing setup:
BSP (British Standard Pipe) threaded
Compression fittings for copper pipe
Flanged ends for larger industrial applications
5. Handle Type & Operation
Quarter-turn operation is standard, but consider lever handle length and material (metal or plastic coated) based on accessibility and environment.
🧰 Application Tips
Always verify WRAS certification before installation – documentation should be available from your supplier.
For buried or hard-to-access installations, consider valves with locking handles or extended stems.
For public/commercial systems, opt for full-bore designs to reduce restriction and maintain flow.
If working in corrosive environments, stainless steel is a smart upgrade.
