22mm Brass Non Return Valve BA-032022000

Secure Your System with a 22mm Brass Non-Return Valve

This high-quality 22mm Brass Non-Return Valve offers a robust solution for controlling water flow and protecting your system. As an essential component for any professional plumbing or heating job, it’s the fit-and-forget part you need to prevent costly backflow and ensure everything runs exactly as it should.

A Critical Component for System Safety and Efficiency

At Heating and Plumbing World, we know that the reputation of a professional rests on the quality of every single component, especially the ones hidden from view. This non return valve 22mm is a perfect example. It’s a small, unassuming part that performs one of the most critical jobs in any system: preventing backflow. For a seasoned engineer, it’s the key to avoiding a frustrating and costly call-back. For a property owner, it’s the guarantee that their system is safe, efficient, and compliant. Its primary function is to act as a one way valve 22mm for water, stopping issues like the draining of radiators in a central heating system or, more critically, the contamination of the mains water supply from back-siphonage.

Reliable, Responsive Design

The secret to its reliability lies in its design. The internal spring-loaded mechanism is incredibly sensitive, requiring a minimum opening pressure of just 0.02 bar to allow water to pass through. When the forward flow stops or reverse pressure is detected, it snaps shut instantly. This responsiveness is vital for protecting other expensive components. A high-performance pump from a leading brand like Grundfos or Stuart Turner is a significant investment, and this valve provides the essential protection it needs to operate efficiently for years to come. Made from solid, corrosion-resistant brass, it’s built to withstand constant use. It performs flawlessly across various pressures and temperatures, handling up to a maximum of 110°C, making it suitable for almost any domestic or light commercial application.

Versatile and Easy to Install

Installation is straightforward for any professional. The valve features standard 22mm compression ends, conforming to BS EN 1252-2 for a secure, leak-proof seal on standard pipework. This versatility allows it to be fitted on either horizontal or vertical pipe runs, providing flexibility when working in tight spaces. Whether you're working on a new hot water cylinder installation from a manufacturer like Gledhill or upgrading an existing network with new fittings, this valve is an indispensable part of your toolkit.
