This is a 12-volt electric solenoid cartridge valve used on Chelsea power take-off (PTO) units, specifically the 277 and 280 series. It is a non‑regulating valve that controls the flow of hydraulic fluid to engage the PTO, directing engine power to auxiliary equipment like hydraulic pumps or winches. The solenoid is replaced when the PTO fails to engage or disengage, often due to coil failure or internal contamination. It operates at 25 watts and is rated for hydraulic pressures up to 300 psi.
