Balancing & Regulating Valves FAQ | Pipetech Supplies

Below you'll find answers to the most common questions about our balancing and regulating valves collection. If you need further technical guidance or help selecting the right valve for your project, our team is ready to assist.

What are balancing and regulating valves used for?

Balancing and regulating valves are used to control and distribute flow rates within heating, cooling, and domestic hot-water systems. They ensure each branch or circuit in a system receives the correct proportion of flow, preventing uneven temperatures and wasted energy across the installation.

What types of balancing valves does Pipetech Supplies stock?

Our collection includes static (manual) balancing valves, double regulating valves, and commissioning-style valves suited to HVAC, chilled water, and general process applications. Specific product availability, sizes, and configurations can be viewed on the collection page, and our team can advise on suitability for your system design.

Which pressure ratings and standards do your balancing valves meet?

Products in this range are manufactured to recognised engineering standards and are typically rated to PN16 or PN25, depending on the model. Where applicable, valves also carry WRAS approval for potable water use. Always check the individual product listing for the exact pressure and temperature ratings.

How do I choose the correct size balancing valve for my system?

Valve sizing depends on the design flow rate, available differential pressure, and the pipe diameter of the circuit. Most manufacturers publish Kv (flow coefficient) data for each valve size, which your design engineer can use to match the valve to the calculated duty. If you need help with selection, contact us with your flow and pressure requirements.

Can these valves be used in both heating and chilled water systems?

Yes. Balancing valves in our range are suitable for use in heating circuits, chilled water loops, and mixed-temperature systems, provided the operating temperature and pressure fall within the valve's stated limits. Check the product datasheet for the permissible temperature range before specifying.

Are your balancing valves WRAS-approved for potable water applications?

Selected models in the collection carry WRAS approval, making them suitable for use in potable (drinking) water systems. WRAS-approved products are clearly identified on their individual product pages. If your project requires potable water compliance, let us know and we can confirm which valves meet that requirement.

Do you offer next-day delivery on balancing and regulating valves?

Next-day delivery is available on most stock items when ordered before the cut-off time. Delivery timescales for non-stock or specialist items may vary, so if your project is time-sensitive, get in touch and we can confirm availability and dispatch dates before you order.

What is the difference between a balancing valve and a standard gate or globe valve?

A balancing valve is specifically designed to set and maintain a predetermined flow rate, and it usually includes measurement ports so the flow can be read during commissioning. Standard gate or globe valves are isolation or throttling devices and do not offer the same level of precise, repeatable flow adjustment or integrated measurement capability.

Can I retrofit balancing valves into an existing system?

Balancing valves can be retrofitted into most existing pipework systems, provided there is adequate straight pipe length upstream and downstream for accurate flow measurement. You will also need to ensure the connection type (flanged, threaded, or compression) matches your existing pipework. A qualified mechanical contractor can advise on the best installation approach for your setup.

How do I get technical support or request a quote for a large order?

You can reach our technical team by phone or email through the contact details on our website. We are happy to help with valve selection, provide datasheets, and offer competitive pricing on bulk or project-quantity orders. With decades of combined industry experience, we support specification-driven procurement from initial enquiry through to delivery.
