PEX Manifolds w/ valve spin closed is a plumbing device which is used to branch out trunk lines. Manifold is a copper device with a single inlet and many outlets to a side. A one inch inlet is branched into 3/4 “outlets which are an exact match for the PEX. It has valves with handles which can be turned a quarter to close or open. The flow of water can be stopped by shutting off the valve. The valve has a ball structure like structure which has a hole right through the center. When the hole is aligned with the pipes wall it allows the flow. The handle when turned in the opposite direction it stops the water from flowing. The closing and the opening of the valve is not automated and has to be done physically.
Manifolds with closed spin valve is used in floor heating systems. The water which comes out of the boiler is diverted to all the rooms in the house or an office building with the help of a manifold. Once again it is branched in the room to send water through many pipes to heat up the floor. The use of manifold has any advantages because one has a choice to allow or disallow water through the pipes. Water can be stopped to a part of the house or even a room without disturbing supply to the rest of the house. The facility helps in shutting down the supply to unwanted rooms and reduces the electricity bill. The outlets can be clearly marked to see which one goes where.
The manifold w/ spin closed is connected to the pipes for the purpose of floor heating. The pipes too are good at retaining heat which is helpful to reduce the bills. Manifolds with four, five and six outlets are found. The distance between two outlets is two inches. They come with adjustable brackets to hold the manifold in place.
Manifold spin closed comes with a 3 /4 “crimp style inlet and 1/2 “outlet and one end of the manifold is closed. It has to be used at the end of a line as it can not continue the trunk line. The popularity of the manifold w/ spin closed is easy to install and highly durable. They also need very few fixtures for installations which makes it all the more desirable.
