Automatic Differential ByPass Valves - Straight Pattern extension - For external use onlyDESCRIPTION: This valve is very effective in systems where various heating loads may simultaneously be excluded from the circuit by the closure of zone control valves and thermostatic or manual radiator valves. It ensures a recirculation proportional to the number of valves that close, thus avoiding noise whilst at the same time maintaining the pump head pressure at a constant value. Fitted between flow and return, it helps prevent unnecessary cycling
