Toshiba Japan UK36 multi-way valve, suitable for EC460B, EC480D, XE700, XE900, SDLG6460

UK36 Multi-way Valve (Toshiba/Nabtesco)
The UK36 is a load-sensing main control valve, commonly referred to as a 'distribution valve,' produced by Toshiba (now Nabtesco) of Japan. It is primarily used in 45–50-ton excavators and is a mainstream original equipment valve for large excavators.
