GATE VALVES & CHECK VALVES Check valve VT.202
Gravity systems are known as heating systems, where the fluid moves naturally. Such systems can often be found in private households. In some cases, flow direction and cycle acceleration determine the pump installed in the bypass. In the absence of forced force (pressure), the coolant circulates naturally. To prevent the liquid from moving in the opposite direction due to gravity, special but not spring-loaded float valves are used.
Purchase a gravity system check valve Valtec (VT.202) and install it in the gravity system in the area parallel to the bypass where the pump is installed. When the pump is running, all the coolant will be bypassed to the heating system.
