ENARDO vent valves and hatches have set the industry standard for more than 70 years. ENARDO thief and gauge hatches with pressure/vacuum relief capability, in-line vent valves and stack vent valves prevent unwanted loss of crude light-ends in low-pressure steel and fiberglass tanks. Valve connections are slip-on compression type, eliminating the need to thread piping in the field. ENARDO's patented technology offers tight sealing and superior resistance to corrosion and sticking.

ENARDO flame arrestors are available in vent-stack and in-line configurations and offer an added measure of safety against ignition of vent gases caused by lightning or other environmental factors.

ENARDO emergency vents supply storage tanks with the extra relief capacity required by OSHA (29CFR 1910.106), API Standard 2000 and NFPA 30 in the event of an external fire. ENARDO pressure/vacuum models also provide high-capacity vacuum flow for emergency pump-out.

ENARDO products are available with special corrosion-resistant coatings for sour gas/crude service.

Typical Applications

Offshore

ENARDO flame arrestors protect piping, ducts and storage tanks against accidental ignition of flammable vapors. Many ENARDO flame arrestors are Factory Mutual (FM) and ATEX certified to ensure the highest level of safety*. Our detonation arrestors feature a patented flame cell design with larger crimp openings than competing products, resulting in lower pressure drop, less plugging and easier cleaning.

ENARDO pressure/vacuum relief valves limit unwanted vapor emissions by maintaining pressure in storage tanks while allowing for thermal inbreathing and outbreathing, as well as normal filling and draining operations. ENARDO uses advanced composite sealing materials to provide superior cold weather performance (to -50°F) and resistance to sticky substances.

ENARDO products are available with special corrosion-resistant coatings for sour gas/crude service.

Typical Applications

ENARDO products are designed and manufactured in ISO 9001-certified facilities.
