FACTORY INSTALLATION PROCEDURE
Overview
This procedure is intended to provide process guidelines for proper
installation of Lee Check Valve, 855 Series, Reverse, Insert product. Section
2 provides an overview of the hole requirements. Section 3 contains the
installation procedure. Section 4 contains a diagram of proper orientation and
position of the product with respect to 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, 855 Series, Reverse, Insert product is purposely designed
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 expansion sealing features. Installation
forces and pressure ratings are based on installations into aluminum housings
or manifolds.
Installation hole specifications as found on Lee Installation Drawing
1INST002350S (Appendix B) will ensure proper operation of the Lee Check Valve,
855 Series, Reverse, Insert product. The hole should be clean, dry, and free
of burrs. Surface finish should not exceed 1.6µm (Ra) with no longitudinal
surface defects. Surface finish requirements must be given special attention.
The expansion section of the Lee Check Valve, 855 Series, Reverse, Insert
product seals and retains the product in the hole. A smooth machined surface
where the product interacts with the hole is needed to seal and retain the
valve properly.
The Lee Company does not recommend the use of coatings or surface treatments
in the area of the installation hole where the product is to be installed.
These may reduce product retention.
Installation
Installation Overview – All Lee Check Valve, 855 Series, Reverse, Insert product use a pin to expand a grooved section of the insert’s body into the housing wall to affect a seal and retain the component. The pin, which has been pre-installed, is driven into the body. The insert is pre-lubricated for proper installation. Do not clean prior to installation.
- The Lee Check Valve, 855 Series, Reverse, Insert product is inserted into the installation hole with the pin end up as shown.
- The installation tool (P/N CCRT0900150S) which is aligned with the installation hole, approaches the hole and contacts the back of the pre-installed pin. The tool drives the pin into the Lee Check Valve, 855 Series, Reverse, Insert product body with a force of 6,672 Newtons maximum. Using friction and penetration, the lands bite into the housing material.
- When the installation tool is retracted, the pin should be flush to within 0.25 mm above flush of the insert body.
3.1 Installation Equipment
The Lee Check Valve, 855 Series, Reverse, Insert product has been designed to
be installed using pneumatic, hydraulic, or electric servo-press equipment. An
electric servo-press system is recommended for high volume production as it
provides detailed feedback for better in process controls of the installation
process. The housing in which the component is to be installed should be held
stationary on a solid surface. The Lee Check Valve, 855 Series, Reverse,
Insert product is expanded by the insertion of the pre-installed and
lubricated expansion pin using an installation tool under load. Adjust the
press stroke to eliminate excess over travel as this may damage the Lee Check
Valve, 855 Series, Reverse, Insert product. Adjust the press supply pressure
to limit the maximum force to 6,672 Newtons.
Insertion should be done using Lee Installation Tool P/N CCRT0900150S (see
Appendix C). The tool and installation hole need to be concentric within 0.03
mm as shown in Diagram of Factory Installation Appendix A. See Appendix D for
further information about the recommended electric servo-press system from
Promess, Inc.
3.2 Standard Factory Installation (see Appendix A)
- Firmly support the housing or manifold in which the valve is to be installed.
- Insert Lee Check Valve, 855 Series, Reverse, Insert product into the installation hole, pin end up, until it is seated on the shoulder of the installation hole.
- The installation force should be 6,672 Newtons maximum using Lee Installation Tool P/N CCRT0900150S. The tool can approach the product at a rate of 20-35 mm/sec. The maximum speed of the tool during installation should be limited to 3 mm/sec.
- Inspect the Lee Check Valve, 855 Series, Reverse, Insert product for proper installation by measuring the depth of the pin relative to the valve body. Installation is complete when the exposed ends (surfaces A and B) are flush to within 0.25mm above flush of each other as shown in Appendix A.
- Retract the tool and follow the same procedure for additional installations.
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.
