Spera Mini Corner Radiator Valve Chrome (PEX)

There are some details that need to be determined in order to choose the appropriate valve for your radiator.
These can be listed as follows:

1. What is your plumbing pipe type?

Your plumbing pipes may be PPRC, sheathed (pex) or iron pipes.

- If the pipe type of your installation is PPRC or iron pipe, you should prefer ½ valve, and if it is a sheathed pipe, you should prefer pex valve.

PPRC SHEATHED IRON

2. What is your connection type?

Your connection type is a necessary detail for the type of valve you will use.

- Your connection can be standard (parallel, bottom opposite end, cross), HB center, HB left or HB right.

In the standard of these connection types, you can use corner pex or corner ½ valve depending on the pipe type.

3. Where does your plumbing connection come from?

Your plumbing pipes may exit from the wall or the floor.

- If your installation has a HB connection (from below), it is important where your installation comes out.

If your pipes come out of the ground in HB connections, you should use straight pex or straight ½ valve depending on the pipe type.
