Two-way valves are essential components in water-based heating systems, primarily functioning as stop-flow valves to regulate water flow. They do not merely constrict flow; instead, they control the flow rate by opening or closing the passage. When a pipe is constricted, the velocity of the water increases to maintain flow continuity, adhering to the principle that flow in equals flow out. Understanding the mechanics of two-way valves is crucial for effective heating system management.
PREREQUISITESHeating system engineers, HVAC technicians, and anyone involved in the design or maintenance of water-based heating systems will benefit from this discussion.
TSN79 said:A water based heating system is to be regulated by 2-way valves. How do these work exactly? Do they simply constrict the flow? Isn't it so that if a pipe is constricted, the velocity simply increases to maintain the flow? I mean, flow in must equal flow out.
