Notes:
1: At 3 bar pressure
2: Although the primary coil pressure rating is 1.0Mpa (10 bar) the 2 port zone valve supplied with the cylinder
is only rated 0.86MPa (8.6 bar). If the cylinder is to be plumbed into a system delivering 1.0MPa (10 bar) a
suitable 2 port zone valve will have to be sourced.
3: Indirect cylinders tested in conformance with BS EN 12897:2016
