Bypass differential valve straight/angled, for high flow capacity

(VT.623.G) Bypass differential valve provides for the stability of flow of heating medium in the secondary contours of heating circuits independent of the flow in the heated floor loops. In case of excess in the set level of drop in pressure the valve directs part of the flow into the bypass of pumping-mixer unit. The use of bypass valve prevents the idle use of pump and enables the circulation of heating medium even in case of fully closed manifold loops. Range of pressure drop settings: from 20 to 60 kPa. The valve body is made of brass brand CW617N and the spring is made of stainless-steel. The spindle and gasket are made of NBR elastomer. The valve is set using a plastic handle. Maximum working temperature of the heating medium: 120°C; nominal working pressure: 10 bar.
