The Groco 3/4" Bronze Electric Flanged Seacock features a "manual override" if the pump fails and "manual lock" if the pump and/or batteries are lost. The feature operates the pump and/or batteries for a pre-set timed period; the pump operates for a pre-set duration; and during the override period the pump and/or batteries are "killed" or "activated" accordingly. The user can be anywhere on the boat with a 12V or 24V source and still control the valve(s) - from the engine room or the helm. The GROCO Electric Flanged Seacock for 12V is a proud member of the GROCO family having received an updated design which features increased actuation forces which have resulted in greater reliability durability and easier use than traditional plastic valves.
