Features & Benefits

SA44 is used at the highest point on the pipeline or at the pump outlet where there is air tightness. To remove the gas inside the pipeline and unblock it to achieve normal operation, if an exhaust valve is not installed, the pipeline may experience air resistance at any time, resulting in the water outlet capacity not meeting the design requirements. Secondly, if there is a power outage during the operation of the pipeline and the pump is stopped, negative pressure may occur in the pipeline in a timely manner, causing vibration or rupture of the pipeline. At this time, the exhaust valve transforms into an intake valve, quickly drawing air into the pipeline to prevent pipeline vibration or rupture. It is used for pipeline exhaust in independent heating systems, centralized heating systems, heating boilers, central air conditioning, floor heating, and solar heating systems.
