22mm non return valve
The 22mm non return valve is a crucial component in plumbing and heating systems, designed to ensure unidirectional fluid flow while preventing backflow. This precision-engineered device features a spring-loaded check mechanism that operates automatically, opening when fluid pressure exceeds a predetermined threshold in the desired direction and closing firmly when flow attempts to reverse. Constructed from high-grade brass or similar durable materials, the 22mm specification makes it particularly suitable for domestic and light commercial applications. The valve's internal components are carefully calibrated to minimize pressure drop while maintaining reliable sealing properties. Its design incorporates a robust seating arrangement that ensures long-term reliability and minimal maintenance requirements. The valve body typically features compression fittings on both ends, facilitating straightforward installation into existing 22mm pipework systems. These valves are essential in protecting boilers, pumps, and other sensitive equipment from damage caused by reverse flow, while also preventing contamination of water supplies. They are commonly deployed in central heating systems, solar thermal installations, and water distribution networks, where their reliable operation is critical for system integrity and efficiency.
