Continuity planning is an essential element in assessing and mitigating risks such as downtime, threats to safe operations and reduced productivity. For safety-critical devices that underpin operational continuity, productivity and reliability, always stock replacement seals, soft-goods kits and consumables—and keep a spare complete unit on hand. Replacing the entire unit is often the quickest way to get up and running and minimise costly downtime. Can you put a price on your downtime? A single device failure can damage your reputation, impact safe operations, jeopardise deadlines and even incur regulatory fines. Including a replacement unit in your continuity plan delivers immediate recovery, peace of mind and minimal operational disruption.

Caveat Emptor – Buyer Beware

Some low-cost breather valve manufacturers can be surprisingly inventive when it comes to justifying the absence of competent leak test certification for new valves. One particularly creative excuse we recently encountered was the claim that biogas digesters are “process vessels” rather than storage tanks, and therefore not subject to the requirements of API 2000 or ISO 28300.

This is unequivocally incorrect.

Breather valves are critical safety devices. Their design, manufacture, testing, and performance must adhere to internationally recognised standards—API 2000 and ISO 28300—which provide the only comprehensive guidance available for operators, manufacturers, service providers, and specifiers.

Deviating from these standards undermines the integrity of the entire system, increases environmental and safety risks, and leaves operators exposed to legal and regulatory consequences. Buyers should remain vigilant and demand full compliance documentation, including verified leak test certification, with every valve—regardless of its intended application.
