Can someone please advise on if the HV4902 or HV5902 is better to add power to my HD Industrial 1841 steering, which uses a (IHC) Ross Hydrapower Steering Gear?
I believe the steering valve is a normally 'open' valve, and there is no Power Beyond port, just pressure and return ports.
Also are the adaptor elbows that comes with the HV5902 a female NPT to 3/4-16 ORB?
From the picture the female end looks like female JIC, which makes more sense than NPT. The HV4902 ports are 3/8" NPT, no elbow provided. It seems like either the HV4902 or HV5902 would work. Tech Support couldn't tell me for certain.
Just for explanation, the Ross steering gear has 3 parts, a steering wheel pump, a valve body, and a cyl attached to the steering gear.
Turning effort applied to the steering wheel overcomes the valve centering spring and hydraulic reaction which moves the valve spool, restricting the return port. This increases the flow to one of the cylinder ports, actuating one end of the piston giving hydraulic power to the linkage where the cylinder is attached.
