Save pump energy and ensure trouble free commissioning of the system with the Frese PV Compact Valve.<\/strong><\/p>\n By design, the valve has a high Kv value which means it achieves the lowest pressure loss of any comparable differential pressure control valve on the market.<\/p>\n Due to fluctuating differential pressures, heating and cooling systems often create noise because the thermostatic control valves are unable to close completely.<\/p>\n Despite the more regular use of variable speed pumps, in larger systems the differential pressure will increase when the system is in a partial load condition. This causes an increase in system noise and the control valves to regulate inefficiently.<\/p>\n The Frese PV Compact Valve ensures a constant differential pressure across the load or circuit and subsequently, very accurate control valve regulation.<\/p>\n Due to the compact design of the valve it is easily installed in both domestic and commercial heating and cooling systems.<\/p>\n Med sit kompakte design kan den let indbygges i anl\u00e6g og fjernevarme units.<\/p>\n This variant is dimensioned so that pressure loss over this component is max 10 kPa, based on the given flow. Regulation intervals<\/strong> Choosing e.g. a PV compact DN25, a differential pressure between flow and returnflow could be regulated to either 5-30 kPa, 20-60 kPa or 20-80 kPa, depending on the variant.<\/p>\n For pump dimensioning, a pressure loss of 10 kPa could be expected.<\/p>\n","protected":false},"featured_media":401,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"pwb-brand":[54],"product_brand":[],"product_cat":[42],"product_tag":[],"class_list":{"0":"post-400","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"pwb-brand-frese-en","7":"product_cat-differential-pressure-control-valves","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"yoast_head":"\nBenefits<\/h2>\n
