Anybody know AKON valves or equivalents?

[etpm]

My Yanmar YM2310 has an aftermarket Bulldog 285 brand FEL. The joystick valve for the FEL is an AKON valve. The only markings on the valve are the letters AKON on the valve handle. I live in the USA and can't find anybody here who sells AKON valves. I would like to add the float function to this valve and the rubber boot protecting the handle linkage needs replacing because it cracking and tearing due to age.
Thanks,
Eric
