Our 22mm pressure reducing valves are designed to stabilise and manage high incoming water pressure, protecting your plumbing system and extending the life of appliances and fixtures. These valves automatically reduce mains pressure to a safe and consistent level, ensuring your system operates smoothly without excessive force that could cause leaks or long-term damage.They’re an essential component in both domestic and light commercial setups, especially in properties where water pressure fluctuates or exceeds recommended limits. Built from durable materials and engineered for accuracy, these valves offer adjustable settings to suit a wide range of system requirements.

Key features and benefits of 22mm Pressure Reducing Valve.

Key Features

Reduces high or fluctuating mains pressure to a consistent and manageable level, helping to protect pipes, valves, and appliances from damage. Ideal for improving performance and extending the lifespan of your plumbing system.

Key Features

Many models allow fine-tuning of outlet pressure to suit system requirements. This gives users flexibility to meet the demands of different water heating or supply setups.

Key Features

Designed for quick installation on 22mm copper or plastic pipes, with minimal space required. Perfect for tight plant rooms or under-sink applications.

Key Features

Helps prevent damage to boilers, showers, washing machines, and taps caused by excessive water pressure. This protection reduces the risk of leaks, breakdowns, and costly repairs.

Key Features

By maintaining a consistent pressure level, the valve reduces unnecessary strain on your system. This leads to smoother operation and improved energy and water efficiency.

Key Features

Regulating pressure helps eliminate sudden surges that can cause banging or knocking sounds in your pipes. This creates a quieter and more stable plumbing environment.

22mm pressure reducing valves play a crucial role in maintaining safe, efficient water flow throughout your property. Without regulation, high water pressure can cause pipe bursts, appliance wear, valve failure, and excessive water usage — all of which can lead to costly repairs or inefficient operation. These valves act as a protective barrier between high-pressure mains and your internal plumbing, ensuring stable flow and preventing strain on every part of the system.

They’re especially important in areas with unpredictable or excessively high mains pressure, where controlling the flow is essential for system health and comfort. Whether you're protecting a boiler, mixer tap, washing machine, or closed heating system, a pressure reducing valve offers peace of mind with minimal maintenance.

22mm pressure reducing valves are commonly installed just after the main stopcock or before key appliances in both residential and light commercial properties. You’ll find them protecting combi boilers, unvented hot water cylinders, electric showers, and washing machines — all of which are vulnerable to high water pressure.

In larger homes or small commercial premises, they’re often used to regulate flow to specific areas, such as loft conversions, annexes, or high-demand bathrooms. Their compatibility with standard 22mm plumbing makes them a popular retrofit or upgrade solution where better control is needed. Whether fitted in a plant room or under a kitchen sink, these valves are a quiet but essential line of defence for your system.

Pressure Reducing Valves automatically reduces and maintains a consistent downstream pressure, regardless of variations in the upstream pressure. This helps protect piping systems and equipment from overpressure.

Some pressure reducing valves, are manufactured in Italy to high quality and engineering standards.

These valves are suitable for water, compressed air, and non-aggressive fluids. Specific models, like the T15 Series, are often used in domestic water systems and light industrial applications.

Pressure Reducing Valves can be made in materials such as brass, bronze, and cast iron depending on the series and application.

Yes, various pressure reducing valve models are available with different sizes and flow capacities to suit both low and high-demand systems.

Direct acting valves use a spring and diaphragm or piston to control pressure directly, while pilot operated valves use a separate pilot valve for more precise control in high-flow systems.

Yes, the outlet pressure can be manually adjusted using the integrated control screw or adjustment mechanism on the valve.

Some models are WRAS approved for potable water applications. Always check the specific model documentation to confirm certification.

Pressure Reducing Valves are available in a range of sizes from DN15 (½") up to DN100 and beyond, depending on the model.

Most models are rated for PN16 pressure systems, with adjustable outlet pressure ranges typically between 1 and 6 bar, depending on the model.

These valves are low-maintenance but should be inspected periodically for debris, wear on internal components, and correct pressure settings.

They are widely used in water supply networks, HVAC systems, commercial buildings, irrigation setups, and industrial processing plants requiring stable pressure control.
