ENARDO Series 800 pressure-only vent valves are designed to relieve pressure only through the vent line. By omitting the vacuum side of the valve, this valve eliminates the possibility of a two-way flow. The Series 800 is designed the same as the “SO” pressure/vacuum series except it eliminates the vacuum side of the valve.
