This Danfoss mixing valve is a three-way valve designed for regulating fluid flow in hydronic heating and cooling systems. The model VRG130 features female National Pipe Thread (FNPT) connections with a size of 1-1/4 inches, facilitating integration into existing piping infrastructure. It has a flow coefficient (Cv) of 18.7, which indicates the valve's capacity to allow a certain volume of fluid to pass through per minute at a given pressure drop, thus providing an indication of its performance in controlling fluid flow within the system.
