Frequently Asked Questions
Q: What Ecoa pallet jack models use the EC PAL-P98-12009 spring-check valve?
A: The EC PAL-P98-12009 spring-check valve is compatible with Ecoa model 6600 pallet jacks. This is a pump-mounted component, so confirm your equipment serial range falls within the 6600 model designation.
Q: What does a spring-check valve do in a hydraulic pump?
A: The spring-check valve controls directional flow and prevents backflow of hydraulic fluid. It allows pressure to build during the pump stroke and blocks reverse flow when the handle is released, working with the neutral spring to hold load.
Q: What are symptoms of a failing spring-check valve?
A: Symptoms include rapid load drift, inability to achieve full lift height, hissing or air noise from the pump area, or erratic handle resistance during pumping. These indicate the valve is not sealing properly.
Q: How often should a spring-check valve be replaced?
A: Spring-check valves typically last through the life of the pallet jack with proper maintenance. Replace when diagnostics show load drift or pressure loss that cannot be resolved by checking fluid level and other pump components.
