SME patented siphon breaker valves (for vacuum) is an open typed pressure balancing model. It opens to let in air to break the state in the sophic pipeline, sync with pumps at discharge.
SME siphon breaker valve series are the patented products, designed and produced in compliance with manufacturer's standard SME208, within framework of prevailing industrial guidelines, flange connection per EN1092.
SME siphon breaker valve is a safety valve, protecting the water pump from backflow by syncing with pump and letting in sufficient air. When the pump is switch on, the siphon breaker valve is closed (sealed) under electromagnet force.
Vice versa, breaker valve is opened under loaded spring force when the pump is turned off. In a siphonic pipeline, that's crucial and enhances the lifetime of pumps.
