Power Steering problem!
Got my car back from paint after a 6 mo stay, Dead battery and control valve puking what was left of the fluid. Valve was old so I replaced it. Hoses are new.Front off ground and I start it and cylinder shoots fast to left and stays. Try to center it...nothing. Locked left Whats up?Steering was fine when I dropped it of at paint.Did the cylinder go out too?WTF happened? Help needed thanks

Will turning steering with the car off to move a car around wipe out the system. I remember moving my truck like that and it over flowed the pump and being sealed is it possible to wipe out the internals of the system?

Did you bleed the ps system? I will assume you know how to adjust that nut but maybe you need to turn it more in the direction that moves the steering to the right. I think there is a limit to how many turns you can turn the nut and its sensitive to balancing the steering system.

Some instructions that might help.
Adjusting Valve and bleeding the system;
11. Bleed power steering pump by turning the pulley backwards
(counter-clockwise as viewed from front) until air bubbles
cease to appear.
12. Tighten pump mounting bolts, torque to 25 ft-lbs and install
drive belt, adjust tension until a 1/2 inch deflection is
obtained with a 5 lb. load (applied at the center of the belt).
Do not overtighten belt since this may cause premature bearing
failure to pump(s).
13. With power steering reservoir full and bled, start engine
momentarily and then shut off. Check reservoir level, if
empty, refill to correct level. Repeat operation until
reservoir level remains constant.
CAUTION: Keep arms away from steering wheel; occasionally, the wheel may start to turn by itself because the control valve has not yet been centered, (every vehicle is slightly different and it is not possible to exactly preset all valves at the factory).
14. If centering is required, remove the metal cap at the end of
the control valve (marked "c"), and adjust the centering by
turning the screw (under cap), while the engine is running at
1500 RPM and the front wheels are off the ground. Steering
will move left or right as the screw is adjusted. Once
steering remains straight, replace cap and continue to next
step.
15. Top-off reservoir, recheck for leaks, check for twisted hoses
during operation of steering system and reset, if required.
S. We recommend that the wheel alignment be checked and adjusted if it is no longer in factory specifications.
E. Trouble shooting:
16. A high pitched noise at the extreme end of steering wheel
travel indicates a slipping drive belt, which requires
tightening.
17. A tendency for the car to steer in one direction (no hands on
wheel) indicates that the control valve requires further
centering adjustment. This assumes that the front end has
first been properly re-aligned.
18. Hydraulic fluid leaks are caused by the following:
a. hose connections not properly tightened, a nut at cylinder
or valve may be "cross-threaded".
b. dirt in the system, causing valve or cylinder to leak.
.

Well I followed what buns posted to no avail. I returned it for a refund and ordered one from Lonestar Caliper. I hope it was defective cause if the new one acts the same way I'm stumped.Can a bad cylinder work only one way or do they just leak when bad? Update coming.

Update
Installed the control valve from Lonestar caliper and was perfectly centered. Should have went there in the first place. Thanks to all who replied

PIF's (pre-installation failure) do happen with new parts. Glad to hear you got a new "working" PSCV that solved your problem.
