WRAS approved, angled body. This valve is very effective in systems where various heating loads may simultaneously be excluded from the circuit because of the closing of control or zone valves. It ensures a recirculation proportional to the number of valves that close avoiding noise and maintaining the head of the pump at a constant value. Fitted between flow and return, it helps prevent unnecessary cycling of the boiler.
