Check Valve
SAE 8-Cartridge – 350 bar
RV08A-51
Poppet Type - Direct Acting
up to 38 l/min
up to 350 bar
The check valve RV08A-51 is a direct
acting poppet type check valve.
The valve allows ow from port 1 to 2,
while normally blocking oil ow in the
opposite direction. The guided check
remains closed by bias spring until
sufcient pressure is applied at port 1 to
open to 2.
Features
High performance version for high cycle rate
Main use to avoid uncontrolled and creeping movements of cylinders under load
and to close off parts from the system
Excellent stability over the entire ow range
All surfaces zinc-plated and corrosion proof
Minimal wear and extended service life due to hardened and ground parts
Low pressure drop due to CFD optimized ow path
Improved abrasion resistance - archieved by a guided and damped piston
