Frequently Asked Questions
Q: What is the function of the WW 6021170 ball valve in a pallet jack hydraulic system?
A: The WW 6021170 ball valve is a shutoff or isolation component that controls hydraulic fluid flow between pump circuits or between the pump and cylinder. It enables manual isolation of pressure sections for maintenance or emergency pressure relief.
Q: Which pallet jack brands and models use the WW 6021170 ball valve?
A: The WW 6021170 is compatible with hydraulic systems in manual and semi-powered pallet jacks from Crown, Toyota, Raymond, Hyster, and similar manufacturers. Verify inlet and outlet port sizes and thread specifications match your equipment.
Q: What material is the WW 6021170 ball valve constructed from?
A: This ball valve uses a brass or stainless steel body with a hardened steel or ceramic ball seat. These materials provide corrosion resistance and durability under repeated cycling and exposure to hydraulic fluid.
Q: What indicates the WW 6021170 ball valve needs replacement?
A: Replace the ball valve if hydraulic fluid leaks from the body or handle connection, the handle becomes difficult or impossible to turn, pressure does not isolate when the valve is closed, or fluid flows uncontrollably in the closed position.
Q: What is the expected service life of the WW 6021170 ball valve?
A: With regular use and proper hydraulic fluid maintenance, the ball valve typically provides 5-10 years of service. Lifespan extends with infrequent operation and clean hydraulic fluid. Inspect annually for external corrosion or leaking.
