1640 Loader Control Valve

[Edkut]

I am trying to find a replacement valve or repair parts for a 1640 loader. OE valve # 70050-01597. It has In, Out, and PB connections as well as the loader up & down and curl connections. The OE valve and parts are discontinued. I am having trouble with the bucket curl function. The valve will not spring load into neutral position. I have replaced the spring and the brass cup with another one that looked compatible does not seem to center itself correctly. Also will bleed down. Not sure if valve is rebuild able or If I could find a suitable aftermarket replacement. Any advice would be appreciated.
Thank You,
Ed
