Galvanized Cast Iron Threaded Vent Check Valve

Product # 521101.500

Overview

Vent check valves allow for the ventilation of ballast and void tanks while preventing contamination of the tank with water or saltwater during rough seas. They offer fully approved protection against pressure buildup for the tank walls and bulkheads while liquid is loaded or unloaded from the tanks. Vertical vent checks mount directly onto the top of vent piping, while inverted vent checks mount onto the end of gooseneck pipes.
