Surge Relief / Anticipator Valve


The Surge Relief Valve for Wastewater protects the system from an excessive rise in pressure subsequent to a stoppage of pumping or a sudden valve closure. The Surge Sentinel Anticipator Valve incorporates the added function of immediately and fully opening upon power outage or other surge producing events in "anticipation" of the resulting pressure surge. For additional configurations, see Product versions below.
