FACTORY INSTALLATION PROCEDURE

Overview

This procedure is intended to provide process guidelines for proper installation of Lee Check Valve, 558 LC Series, Press-In product in forward flow orientation. Section 2 provides an overview of the installation hole requirements. Section 3 contains the installation procedure and customer assembly process recommendations. Section 4 contains reference information on the installation hole and installation tool.

Compliance with this installation procedure will ensure optimal product performance. Please contact your local Lee Company Sales Representative for questions concerning installation of Lee Company products.

Installation Hole Requirements

The Lee Check Valve, 558 LC Series, Press-In product is purposely designed for installation into plastic manifolds or fittings and to perform well under adverse conditions. Therefore, the installation hole specifications outlined in this section should be followed precisely to ensure proper function of the product’s retention and sealing features.

Installation hole specifications as found on Lee Installation Hole Drawing 1INST072393S (Appendix A) will ensure proper operation of the Lee Check Valve, 558 LC Series, Press-In product. The hole should be clean, dry, and free of burrs/flash. The series of smoothly curved lands of the Lee Check Valve, 558 LC Series, Press-In product allow the valve to be pressed in while the plastic flows into the adjacent grooves. Some plastics with a lot of elongation, such as Polypropylene, Nylon, Acetal, Polyethylene and PEEK, cold flow into the grooves affecting retention and sealing.

Other plastics, such as acrylic and polycarbonate, are rigid and therefore the material must be heat flowed around the component. For installation into these types of plastics contact your local Lee Company Sales Representative for more information.

Factory Best Practices

Examine the condition of the Installation Tool at appropriate intervals and replace if damaged or chipped.
Clean feed bowls once per day.
Turn off vibratory feed bowl when the assembly station is idle, or if the feed rail is full of parts.
Use the minimum vibration setting to advance valves in the feed bowl.
If the check valve is blown into the assembly area from the feed rail, minimize the air pressure at which the check valve is blown into the assembly area to prevent possible damage.
