Imperial PVC & Metal Manual Valves FAQ

Below you'll find answers to the most common questions about our Imperial PVC and Metal Manual Valves collection. If you need further help selecting the right valve for your application, our technical team is always happy to assist.

What types of imperial manual valves does PipeTech stock?

Our collection includes a range of imperial-sized manual valves in both PVC and metal construction. You'll find ball valves, butterfly valves, gate valves, and check valves among other types, all sized in imperial measurements to suit existing pipework systems commonly found across UK industrial and commercial installations.

What is the difference between PVC and metal manual valves?

PVC valves are lightweight, corrosion-resistant, and well suited to water treatment, chemical dosing, and other applications where chemical compatibility is important. Metal valves (typically brass, stainless steel, or cast iron) offer greater mechanical strength and are better suited to higher-pressure or higher-temperature systems. Our team can help you choose the right material for your specific application.

How do I know which valve size I need?

Imperial valve sizes correspond to the nominal bore of your existing pipework, measured in inches. Check the markings on your current pipe or valve, or measure the outside diameter and cross-reference it with standard imperial pipe sizing charts. If you're unsure, contact us with your pipe dimensions and we'll confirm the correct size for you.

Are these valves suitable for potable water systems?

Certain valves in this collection are approved for use with potable water, but suitability depends on the specific product and its material certification. Check the individual product listing for WRAS approval or equivalent certification details. If you can't find the information you need, get in touch and we'll confirm whether a particular valve meets potable water standards.

Can I use imperial valves with metric pipework?

Imperial and metric pipe sizes are not directly interchangeable, so fitting an imperial valve to metric pipework typically requires an adapter or transition fitting. We stock a wide range of adapters that make this conversion straightforward. Let us know your metric pipe size and the imperial valve you're interested in, and we'll recommend the right connector.

What pressure ratings are available?

Pressure ratings vary by valve type, size, and material. Each product listing in this collection specifies its maximum working pressure, often expressed in bar or PSI. Always select a valve rated above the maximum operating pressure of your system, and account for any pressure surges or water hammer that may occur during operation.

How much does delivery cost, and how quickly will my order arrive?

We offer flat-rate UK delivery at just £12 on all orders, regardless of size or weight. Most in-stock items are dispatched promptly for fast, dependable nationwide delivery. If your project is time-sensitive, contact us and we'll give you an accurate delivery estimate before you place your order.

Can your team help me specify the right valve for my application?

Absolutely. Our team combines expert technical knowledge with a hands-on, problem-solving approach. Tell us about your system (media type, pressure, temperature, pipe size, and application) and we'll recommend the most suitable valve from our range. We're here to help you find the right solution, not just sell you a product.

What if I order the wrong valve or need to return an item?
