In order to give compliance with N.H.S. specification DO8 the table below lists the
conditions for normal use. These valves will perform adequately outside these
parameters, however they cannot be guaranteed by the scheme to operate as Type 3
valves. If they are required to work with other supply conditions an engineer must carry
out a risk assessment and satisfy themselves that the valves are suitable for use.
