Valve Rebuild Kit Contents

The Dayton 066059 Valve Rebuild Kit supplies a complete set of replacement internals for valve maintenance. It includes a gasket, piston assembly, piston ring, plunger assembly and spring. Printed instructions are also provided in the package. Technicians use this kit to restore sealing and actuation performance on compatible valves.

Installation Practicalities

The kit is designed for standard bench servicing using common hand tools. No specialised equipment or external power is required to disassemble the valve and fit the new components. The included instructions guide the reassembly sequence so that the repaired unit returns to normal operating pressure and flow characteristics.

What the Instructions Change

Having the step-by-step guide in the box removes the need to locate a separate service manual before starting work. It reduces the risk of incorrect component orientation or missed torque steps during reassembly. The result is a faster, more reliable rebuild that returns the valve to service with minimal downtime.

Questions about this item

How do I install the piston assembly and plunger assembly in the 066059 valve rebuild kit without misaligning the spring?

Follow the included instructions to seat the piston assembly and piston ring first, then insert the plunger assembly and spring in sequence, ensuring the spring locates correctly in its recess before tightening the valve body.

Which components in the 066059 kit will need replacement again after extended service?

The piston ring, gasket, spring and plunger assembly are wear items; expect to replace the piston ring and gasket at each rebuild, and the spring if it loses tension or the plunger if it shows scoring.

What is the first limitation that appears when the rebuilt valve runs continuously under pressure?

The spring will fatigue first under sustained pressure cycles, reducing return force and causing the plunger to seat slowly or incompletely.
