LEE IMH Chek™ Valve – 6.5mm CCPI Series Press-In

Product catalog summary

Product Overview
The Lee Company's 6.5 mm Press-In Chek™ Valve is a miniature cartridge-style check valve designed for installation into plastics. It offers more than twice the flow capacity compared to the 4.5 mm model and features stainless steel construction for compatibility with various fluids and gases. The valve's barbed design ensures easy installation, retention, and prevents leakage.

Performance Specifications

Lohm Rate: 75 Lohms
Leakage: 20 sccm/min (max) at 172 kPa (25 psid) on air; 1 Drop/min (max) on water
Materials: Stainless Steel for Body, Cage, Ball, and Spring
Maximum working pressure depends on housing material, configuration, and operating conditions

Installation Features

100% Tested to eliminate rework
Bidirectional installation for forward or reverse flow capabilities
Simple press-in design for easy installation
Leak-tight for efficient system performance

Cracking Pressure Options
Various part numbers are available with different cracking pressures ranging from 0 kPa to 500 kPa, allowing for customization based on specific application needs.

Lohm Laws and Liquid Flow Formula
The document explains the Lohm system, a method for defining fluid resistance in hydraulic components, similar to Ohms in electrical systems. It includes formulas for calculating flow resistance, incorporating factors for liquid density and viscosity.

Installation Instructions
The valve can be installed by pressing it into a plastic installation hole, suitable for materials like Nylon, Polyethylene, Polypropylene, Acetal, and PEEK. Specific tools are available for forward and reverse flow installations.

LEE IMH Chek™ Valve – 6.5mm CCPI Series Press-In-1

product data sheet The Lee Company’s new 6.5 mm Press-In Chek™ is the latest addition to our line of miniature cartridge-style check valves specifically designed for installation into plastics. This new valve offers more than twice the flow capacity over the existing 4.5 mm model. The valve features all stainless steel construction, providing compatibility with a wide range of fluids and gases. Its unique barbed design provides easy “press-in” installation, ensures retention and prevents any by-pass leakage around the valve. A high-quality metal to metal seat provides low leakage and a highly repeatable cracking pressure. This robust design and 100% functional testing ensures consistent long term performance. ■ 100% Tested - Eliminates Rework ■ Bidirectional Installation - Provides Forward or Reverse Flow Capabilities - Design Flexibility ■ Press-in Design - Simple Installation ■ Leak Tight - Efficient System Performance CHEK VALVE FLOW DIRECTION CHECKED DIRECTION Lohm Rate: 75 Lohms* Leakage: 20 sccm/min.
