If no local Strainer is required.
The flow side will include a Filtermate DZR isolation valve a drain and test point.
On the return side a 2 port pressure independent control valve will be included of the rising stem type whereby no valve stroke is lost when the valve is pre-set. The flow rate should remain adjustable without removing the actuator and lockable by means of a memory stop.
The control valve will be actuated by means of (delete as appropriate) a motorised actuator, thermoelectric actuator, TRV sensor. The control characteristic should be characterised such as to provide near linear temperature control.

If Insulation of Valvesets is Required
Each valve assembly is to be mounted in an insulation box manufactured from water blown Polyisocyanurate material with a Class 'O' external foil scrim finish.
The insulation material should have a thermal efficiency of k=0.023 w/m°C and be at least 25mm thick. An EPDM compressive vapour seal between the two halves of the box will be provided as a barrier to condensation.
The insulation box should have a 0 Ozone Depletion rating (ODP) and low Global warming potential (GWP).
If Bracket Work is Required
For each terminal unit a pair of Xterminator valve sets will be bracketed together in tandem.
The bracket shall be thermally isolated by means of stepped nylon washers in order to prevent heat bridging.
