Frequently Asked Questions
Q: What does the HY 355866 check valve do?
A: The HY 355866 is a hydraulic check valve kit designed to prevent backflow in electric lift truck pump circuits. It allows fluid to flow in one direction only, ensuring stable load holding and preventing drift when the lift truck hydraulics are stationary.
Q: What is the valve type and construction of the HY 355866?
A: The HY 355866 is a unidirectional check valve with a precision machined hydraulic-grade steel body. This construction provides reliable backflow prevention and meets Hyster OEM specifications for durability in demanding lift truck applications.
Q: How do you know if the HY 355866 check valve is failing?
A: Signs of check valve failure include load drift (mast slowly lowering when stationary), sudden pressure loss, or noisy operation in the pump circuit. If the lift truck cannot hold a load steady or hydraulic pressure drops unexpectedly, the check valve may need replacement.
Q: Is the HY 355866 sold as a complete kit?
A: Yes. The HY 355866 is supplied as a complete check valve kit manufactured to Hyster OEM specifications. The kit includes all components needed for proper backflow prevention in the pump circuit.
