Frequently Asked Questions
Q: What does the JT PT2748W-84 Overload Valve Kit do?
A: The JT PT2748W-84 is a complete hydraulic relief valve assembly for Jet manual pallet jacks, model PT2748W. It limits maximum hydraulic system pressure and protects the pump and cylinders from damage due to overload conditions.
Q: Which Jet pallet jack models does this valve kit fit?
A: The JT PT2748W-84 is designed for Jet manual pallet jacks, model W and PT2748W series. Confirm your jack serial number and model designation before ordering to ensure compatibility.
Q: What components are included in this valve kit?
A: The JT PT2748W-84 kit includes a precision-machined steel valve body, calibrated relief spring, washer, and nut. All components work together as a complete assembly and are pre-matched for proper valve operation.
Q: What symptoms indicate this valve assembly needs replacement?
A: Replace the valve kit if the jack fails to hold a load under normal conditions, if pressure relief occurs prematurely, if hydraulic fluid weeps from the valve body, or during routine overhaul of the Jet PT2748W system.
Q: How is the pressure calibration maintained in this valve assembly?
A: The calibrated spring within the JT PT2748W-84 is engineered to maintain precise pressure relief settings. The spring, valve body, and washer assembly must be used together as a complete kit to maintain correct pressure relief calibration.
Q: What is the valve body material specification?
A: The JT PT2748W-84 valve body is manufactured from precision-machined steel, rated for the full operating pressure range of Jet PT2748W pallet jacks. The material resists corrosion and maintains dimensional accuracy under cyclic pressure loading.
