Gate valves play a vital role in providing secure isolation across water and heating systems, and at BES, we draw on more than 50 years supporting installers to stock reliable brass and DZR options with compression and BSP threaded connections. A gate valve operates by lifting a gate or wedge out of the fluid pathway, creating straight-line flow with minimal restriction when open. This makes them ideal for applications requiring a full-bore, low-resistance passage.
Our range includes wheelhead gate valves, lockshield gate valves, chrome-plated gate valves and lockshield valve keys, supporting everything from everyday plumbing installations to more specialist isolation points in plant rooms and distribution networks. And with competitive pricing, hassle-free 30-day returns, fast dispatch and free delivery over £50, shopping online with us couldn't be easier.

Each design delivers full-bore flow when open and secure shut-off when closed, supporting straightforward maintenance and system control. Gate valves are not designed for throttling; instead, they excel as isolation valves for water, heating and mechanical services.
Chrome-plated gate valves offer a cleaner, decorative finish for exposed pipework, while maintaining the performance of a traditional brass body. These are often used in plant rooms, airing cupboards and visible domestic pipework where appearance matters. Options include the Chrome Plated Gate Valve – 15mm and Chrome Plated Gate Valve – 22mm, both suitable for hot and cold water installations and easy to integrate with copper pipe using standard compression fittings.
Designed for controlled operation and to prevent unauthorised adjustment, lockshield gate valves are widely used on distribution pipework, risers and system branches where stable flow conditions must be maintained. Installers can choose from models such as Lockshield Gate Valve – 15mm Compression Brass, Lockshield Gate Valve – 22mm Compression Brass, Lockshield Gate Valve – 22mm Brass BS 5154 or Lockshield Gate Valve – 28mm Comp. Brass BS 5154.
Where restricted operation is required, the Lockshield Gate Valve Key provides secure opening and closing of the valve without altering system settings.
Wheelhead gate valves are among the most common isolation valves for general plumbing and heating systems, suitable for service valves, plant rooms, pumps, distribution pipework, and mechanical system branches. BES stocks a broad selection, ranging from small-bore domestic valves to large industrial sizes. Popular compression models include Wheelhead Gate Valve – 15mm Compression Brass, Wheelhead Gate Valve – 22mm Compression Brass BS 5154, Wheelhead Gate Valve – 28mm Compression Brass, Wheelhead Gate Valve – 35mm Compression Brass BS 5154, Wheelhead Gate Valve – 42mm Compression DZR BS 5154 or Wheelhead Gate Valve – 54mm Compression DZR BS 5154.
For mechanical and commercial applications requiring threaded connections, options include: Wheelhead Gate Valve – 1/2" BSP F Brass PN16, Wheelhead Gate Valve – 3/4" BSP F Brass PN16, Wheelhead Gate Valve – 1" BSP F Brass PN16, Wheelhead Gate Valve – 1.1/4" BSP F Brass, Wheelhead Gate Valve – 1.1/2" BSP F Brass PN16, Wheelhead Gate Valve – 2" BSP F Brass PN16, Wheelhead Gate Valve Brass – 3" BSP F or Wheelhead Gate Valve – 4" BSP F Brass.
These valves provide full-flow characteristics with minimal pressure drop and are typically installed where dependable isolation is needed for servicing pumps, filters, calorifiers or distribution lines.
Selecting the right gate valve depends on pipe size, connection type and the environment in which it will be installed. Standard brass valves are suitable for most domestic and commercial systems, while DZR brass offers improved protection against dezincification where water conditions are more aggressive, or installations demand additional corrosion resistance.
Compression-ended gate valves are typically preferred for copper pipework because they offer quick, reliable installation with minimal tools. In contrast, female BSP threaded valves are commonly used in plant rooms, mechanical assemblies and industrial systems where components may be dismantled or replaced during maintenance.
Operation style is also important. Wheelhead gate valves are designed for everyday manual use and offer straightforward control. Lockshield variants, however, restrict operation and help maintain consistent system settings, making them ideal for distribution pipework or system balancing points.
If you’re unsure which valve best suits your application, the BES technical team can provide guidance based on system design, pipe material and operating pressures.
Gate valves are typically used for:
Isolating sections of hot and cold water distribution
Branch isolation on heating circuits
Plant room equipment such as pumps, strainers and calorifiers
Larger mechanical services in commercial buildings
Systems where a full-bore, low-restriction valve is required for good flow performance
Domestic sizes (15mm–28mm) are commonly used for zone isolation, while larger BSP threaded gate valves support commercial and industrial installations.
Gate valves and ball valves are often used for similar purposes, but they suit different installation preferences. Gate valves offer smooth, progressive operation and a full-bore pathway ideal for large or long distribution runs. Ball valves provide quicker quarter-turn operation and are more suitable where frequent isolation is required. However, ball valves can introduce slightly more flow resistance, especially in larger sizes, whereas gate valves maintain a straighter flow path.
Gate valves should not be used for throttling; operation between fully open and fully closed can cause wear to the gate mechanism.
BES has supplied trade-quality plumbing products for over five decades, selecting gate valves for durability, consistent performance and compatibility with UK plumbing standards. Every product listing provides the key specifications installers need, including materials, pressure ratings and connection details.

What is a gate valve used for in plumbing?
Gate valves are used to isolate sections of a plumbing or heating system. Their full-bore design allows water to pass with minimal resistance when open, making them ideal for distribution lines and branch isolation.
What is a lockshield gate valve?
A lockshield gate valve restricts operation using a removable key, preventing accidental or unauthorised adjustment. This helps maintain stable flow conditions, particularly in distribution systems or risers.
Gate valve vs. ball valve: which is better?
Ball valves are faster to operate and ideal for frequent isolation. Gate valves offer smoother operation and less flow restriction on larger pipework. The best choice depends on installation needs rather than one being universally better.
How do I choose the right size gate valve?
Gate valves should match the pipework diameter; for example, 15mm and 22mm for domestic copper systems or larger BSP sizes for commercial lines. Use compression valves for copper pipes and BSP threaded valves for mechanical installations.
Are these valves WRAS approved?
Always refer to the individual product listing for confirmation of approvals.
What are common problems with gate valves?
Over time, gate valves can become stiff due to mineral buildup or inactivity. Partially opening or throttling the valve can also cause wear to the gate mechanism. Installing them in accessible positions and operating them fully open or closed helps maintain reliability.
What are the pressure ratings for BES gate valves?
Many threaded gate valves are rated PN16, but ratings vary by model. Always check the product’s technical specifications for exact pressure and temperature limits.
Can gate valves be used on central heating systems?
Yes. Gate valves are commonly used for branch isolation on heating circuits. For sealed heating systems, installation should always be carried out by a competent person.
