Enardo Series 800-PSO pressure-only vent valves are designed to relieve pressure only through the vent line. By omitting the vacuum side, 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.

EnardoTM vent valves are designed to provide trouble free operation with a minimum maintenance. The primary functions of these valves are to prevent the loss of vapors in a closed storage system and provide pressure and vacuum relief.

EnardoTM ES-800-SO in-line vent valves represent the latest development in high-performance, tight-sealing tank venting products and complement the industry-leading Enardo ES-660 Series thief hatch product line. With a leakage rate of no more than 1.0 SCFH at 90% of set point, the Enardo ES-800-SO offers unparalleled vent valve performance.

Enardo Series 800-SO in-line vent valves prevent the escape of light ends of crude by maintaining pressure in the storage tank. Learn more here at Emerson.com.
