About the Product
The Fainger make End of line Pressure /Vacuum Relief Valve (also known as Conservation Vent) are specially designed for tank protection and is intended to use where pressure & vacuum relief is required.
As the pressure builds in the tank, there is a differential created across the pressure relief Pallet. When this differential becomes great enough to lift the pallet; the pallet unseats / lifts and allows Vapor flow out of the tank.
The Pallet Re-Seats when the differential becomes low. Similarly, when vacuum is developed in the tank, the differential across the vacuum pallet eventually becomes great enough to lift the vacuum pallet and allows air to flow into the tank. The vacuum pallet re-seats when the differential is low.

Features
- Serialized unit for easy identification and traceability
- Easy inspection and easy maintenance
- Automatic condensate drainage design
- Pallet assembly guides and center pallet stem guide to ensure proper alignment of pallet assembly on the seat and smooth lifting and reseating action
- “Air-cushion” pallet design for better sealing and low leakage performance
- Designed and tested according to API 2000
