Made from solid brass with a threaded connection, they are straightforward to install and suit water, oil, and gas applications. The range covers sizes from 4 points (DN15) up to 4 inches (DN100), including both horizontal and vertical check valve options, so you can select the right fit for your pipe layout. Each valve is built without moving springs or complex internal parts, reducing the likelihood of mechanical failure over time.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Brass horizontal check valve with threaded ends in 1 inch size for plumbing systems\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1447\/2025-09-30\/original-image\/1618382665393.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThese check valves are designed for practical, long-term use in residential, commercial, and light industrial settings. The brass body provides good corrosion resistance and mechanical strength, while the threaded ends allow easy integration into new or existing pipework. Available in a wide range of diameters, they accommodate systems of different scales.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe valve body is made entirely from brass, a material known for its durability and natural resistance to rust. Brass also handles a range of fluids including hot and cold water, oil, and non-corrosive gases, without degrading. The internal seating mechanism opens under forward flow pressure and closes automatically when flow stops, preventing backflow without manual intervention.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eSizes are offered from 4 points (DN15) through to 4 inches (DN100), with both horizontal and vertical configurations available. Each size uses standard BSP threaded connections, making it compatible with common pipe fittings. The 4-point and 6-point sizes suit smaller domestic installations, while the 1-inch to 4-inch sizes serve larger commercial or industrial systems.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Brass horizontal check valve with threaded ends in 1 inch size for plumbing systems\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1447\/2025-09-30\/original-image\/1618382665406.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThese valves regulate flow direction in multiple fluid and gas systems.
