Disc 31/20 Check Valve

The Disc 31/20 Check Valve by BILSTEIN is a precision hydraulic component designed for use in high-performance shock absorber systems. This check valve effectively regulates fluid flow within suspension applications, preventing backflow and maintaining consistent damping characteristics during vehicle operation. It is particularly useful in various suspension systems where reliability and controlled ride quality are important.

Constructed from hardened steel, the Disc 31/20 Check Valve features a disc-type poppet design that opens and closes based on differential pressure across the valve body. This design minimizes pressure spikes, reduces cavitation, and extends the lifespan of shock absorbers by ensuring smooth and predictable fluid dynamics. The compact dimensions make it easy to integrate into both OEM and aftermarket shock assemblies.

Ideal for technicians and suspension specialists, the Disc 31/20 Check Valve is compatible with BILSTEIN E4-FE1 shock absorber series. It supports both single-shock replacements and complete suspension rebuilds, making it a versatile choice for vehicle builders and restorers looking to enhance their suspension systems.
