Inch High Quality Brass Non-Return Valve - Robust, Rustproof and Watertight - for Pumps, Fountains, Washing Machines, Gardens, Rainwater, and Barrels

【High Quality】: The check valve is made of solid brass, corrosion-resistant, durable, with good high-temperature ductility, low magnetic conductivity, and a long service life. 【Operating Temperature】: -4 to +212°F (-20 to +100°C). Maximum working pressure 25/18/12 bar (PN-25/PN-18/PN-12) 【High Safety】: The check valve is also very easy to install and prevents liquid backflow. A few turns are all it takes to tighten the valve and prevent leaks. 【Perfect Choice】: Our check valves can be connected to all 1-inch male threaded pipes, hoses, and fittings according to BSP standards. This type of valve is very effective at preventing liquid leaks. Installation must be horizontal to allow only one-way fluid flow, preventing accidents. 【Wide range of application】: Suitable for water, steam, oil, nitric acid, urea, etc. Widely used in mechanical equipment, water supply and drainage, industrial plants, drinking water plants, etc. The most important properties of a check valve are durability, corrosion resistance, sealing, and compatibility with fittings and connections. We have designed our check valves to precisely meet these requirements. Thanks to the high-quality material, our valves are durable and rust-free. The cap, stem, and spring are also made of brass or stainless steel, not plastic, which means the check valve will withstand high loads safely and for a long time. Furthermore, it can withstand high temperatures and pressures (Note: water must be drained and pipes drained in freezing weather. Or you can remove the check valve in winter for added safety). With just a few turns, the valve is securely connected using sealing material and the appropriate wrench.
