What these photographs show
Screw-in steel cartridge with a hex body, two O-rings, a threaded nose with side holes, and a small stem at the opposite end. Hex stamp: U.S. PATENT 6,805,155 & 7,069,945. No HydraForce logo, no RV model, no cavity code, and no pressure setting are on these faces.
Those two numbers are U.S. patents assigned to HydraForce, Inc. for a cartridge relief valve with reverse-flow check. HydraForce datasheets print the same patents on RV10-28 and RV50-28 families. This housing does not say which family, so we do not pick one.
The yellow carton behind the hand is USHA Original Assembly — Air Cooled Piston Assembly Kit. That is a different SKU in the same photo. It is not this cartridge and is not used as the brand here.
Not this product: Parker C5V08 check valve, Rexroth R900412527 directional valve, Parker COP024HSN coil.
Applications — only what is verified
Verified: a screw-in hydraulic cartridge stamped with HydraForce relief patents 6,805,155 and 7,069,945. Public HydraForce copy describes those patents on pilot-operated relief cartridges with reverse free flow. Pressure range, cavity (for example VC10-2), torque, and machine list are not printed on this sample.
Send a photo of the valve you are replacing, the cavity, and any RV / adjustment code on the hex or adjuster.
