Bypass differential valve with union pipes, with thermometers

(VT.0667T.0) The VALTEC bypasses with through differential valve are used with connector kits VTc.594 EMNX and 596.EMNX to direct the flow of medium to the return line in case of the consumption through the collector loop falls below the given value. This helps maintain the hydraulic features of the system independent of the positioning of the regulatory collector loops (manual, thermostatic valves etc), prevent the pump from working in case of “closed gate”. VT.0667T bypass is a through fitting (mounted before the collector unit), and is combined with immersion thermometer VT.0617. This item is made of hot pressed nickel-plated brass brand CW617N and the through pipe is made of nickel-plated copper.
