Max operating pressure (PRV) 0.35MPa (3.5 bar)
Expansion relief valve setting 0.6MPa (6 bar)
T&P valve setting 1.0MPa (10 bar)/90°C
Maximum primary pressure 1.0MPa (10 bar)
Presure drop across coil 0.02MPa (0.2bar)
Notes:
1. Indirect cylinders tested in accordance with BS EN 12897:2006.
2. Heat up time from cold through 45°C, based on a flow temperature of 80°C +/- 2°C & normal volume.
3. Although the primary coil pressure rating is 1.0MPa (10bar) the 2 port zone valve and coil compression
nuts supplied with the cylinder is only rated 0.86MPa (0.86 bar). If the cylinder is to be plumbed into a
system delivering 1.0MPa (10 bar) a suitable 2 port zone valve and the coil compression nuts supplied will
have to be sourced.
