• Overboard venting is required if PVL or HVL series is used in an exhaust system.
• HVL and PVL series vented loops assure clog-free anti-siphon protection for sanitation or engine exhaust systems. The oversized vent valve can easily be removed for inspection or cleaning without tools.
• Mount Hardware is included.

The GROCO Bronze Vented Loop, part number HVL-2000, is designed to provide anti-siphon protection for sanitation or engine exhaust systems. This component allows air to enter the system to break a siphon, preventing backflow, but is engineered to contain air and odors within the system rather than allowing them to escape. The unit features an oversized vent valve that can be removed without tools for routine inspection or cleaning, contributing to clog-free operation. Its cap is threaded 1/2" NPT, offering the option to accept a barb fitting for overboard venting, which is a requirement when this series is integrated into an exhaust system. Mounting hardware is included, facilitating installation. This vented loop is suitable for IT infrastructure managers or facilities personnel responsible for maintaining systems where siphon prevention is critical.
