The PROTEGO® ER/V-F is a specialized version of the emergency pressure relief valve line, specifically distinguished by its spring-loaded design. This modification allows the valve to handle significantly higher set pressures—ranging from +60 mbar up to +500 mbar—than the weight-loaded ER/V or ER-V-LP models. It remains a "full lift type" valve, meaning it reaches its maximum discharge capacity with only a 10% pressure increase above the set point, providing rapid and reliable emergency venting for storage tanks and silos.
Despite its ability to manage higher pressures, the ER/V-F maintains the high standard of sealing and flow efficiency expected from the PROTEGO® line. The precision-lapped valve pallet and high-grade stainless steel seat ensure minimal product loss and reduced environmental impact. Housed in a sturdy, weather-protected casing, it is built for durability in harsh conditions and is fully certified for use in explosion-hazardous areas, making it an ideal choice for high-pressure API-compliant storage systems.
