Manifold is a distribution and collection device used in water systems to connect the supply and return water of various heating pipes, also known as a water splitter or water collection and distribution device. It mainly consists of three parts: water distributor, water collector, and fixed bracket. It is commonly used in floor heating systems, air conditioning water systems, or other industrial water systems, responsible for managing several branch pipelines, including return water branch and supply water branch. The main function of the water divider is to open and close the water flow in the underfloor heating loop, achieving the purpose of room heating and temperature regulation. At the same time, the water separator also has the advantages of convenient user operation, easy maintenance, and reducing system pressure difference.
