What is ADBV ?

Parts of an Oil Filter 
 Gasket - provides exterior seal between the filter and engine at the engine mounting surface.  
 Mounting Plate - prevents deflection (movement) at the gasket sealing surface. Heavy gage steel plate provides for threaded attachment to the engine.  
 Inner Element Support - provides inner element stabilization and a positive seal between the inner element and the mounting plate to prevent the bypass of unfiltered oil.  
 Upper End Cap - retains element end sealant and filter media, provides an outlet for clean oil, and provides structural rigidity to the pleated media.  
 Lower End Cap - retains element end sealant and filter media.  
 Arch-pleated, Prescription-blended Filter Media - provides a more than adequate filter area. The element has a controlled porosity blended media to assure complete filtration of the oil.  
 Spiral-wound Center Tube - provides internal element support. The spiral design greatly reduces initial flow restriction when compared to other designs.  
 Coiled Spring - ensures a constant load on the inner element to maintain the seal between the upper element end cap, the inner element support, and the mounting plate even during pressure surge situations.  
 Filter Canister - encloses the assembly with a mechanically-locked double seam. The canister provides "flutes" at the closed end for ease of removal with an oil filter wrench. 
 Silicone Anti-Drainback Valve - Stays flexible in extreme temperatures, improves oil flow and keeps oil in filter to prevent engine destroying dry starts. Also provides lasting protection to meet new vehicle manufacturers longer recommended oil change schedules. Nitrile valves can harden and become ineffective over time.
