Technical data sheet Pressure reducing valve Applications and special features • Control and maintain the downstream pressure at an adjustable reduced value, whether there is a flow or not. • Keep an outlet pressure at a constant value, even by variation of the upstream pressure (the down-stream pressure cannot vary more than 10 % of the variation of the upstream pressure, according to the Standard). • All internal component in bronze, specially adapted for sea water and aggresive water. • No maintenance required, not affected by scale or dirt. • Can be installed in any position. • Guarantee a high flow rate at a constant outlet pressure because of low head loss. • Work as pressure reducing valve (standard terminology) as well as “regulator” and as “pressure regulating valve” (when applies for gas). • Downstream setting : 1bar to 6 bar; indicative value according to EN1567 • Adjustable : supplied non adjusted. • 2 pressure gauge connections 1/4” and drain at the bottom of the casing. Technical description L1, L2, G1 and G2 correspond to liquids/gas classified into degree of danger according to the Pressure Equipment Directive (PED). The article 3.3 applies to equipments with no CE marking. Overall dimensions • Connection : female/female, BSP thread • Downstream pressure gauge connection : 1/4” • Permissible operating pressure PFA - water : See table • Maximum permissible pressure PS - other mediums : See table •θ: Mini. -10 °C Maxi. in permanent service : 80 °C (40°C domestic fuel oil) • Mediums : water, sea water, aggresive water • Approvals: ACS • International construction Standards : Pressure reducing valves EN 1567 Thread connection NF EN ISO 228
