product data sheet LEE IMH Chek™ Valve - 855 LC2 Series Press-In ■ 100% Tested - Eliminates Rework ■ Bidirectional Installation - Provides Forward or Reverse Flow Capabilities - Design Flexibility ■ Press-in Design - Simple Installation ■ Leak Tight - Efficient System Performance The Lee Company’s Industrial MicroHydraulics Group (IMH) introduces the newest addition to our line of miniature cartridge-style check valves specifically designed for installation into plastics. The new 855 LC2 Series Press-In Chek Valve offers more than a 65% increase in flow capacity over the existing 8.0 mm CCPI series check valve. This new 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 bypass leakage around the valve. A high quality metal to metal seat provides low leakage and highly repeatable cracking pressure. This robust design and 100% functional testing ensures consistent long term performance. CHEK VALVE FLOW DIRECTION CHECKED DIRECTION AP vs. Flow on Water @80°F (27°C) All dimensions in millimeters, except where noted. Flow Curve for 40 kPa Valve PERFORMANCE Lohm Rate: 45 Lohms* Leakage: 20 sccm/min. (max.) @172 kPa (25 psid) on air 1 Drop/min. (max.) on water Materials: Body, Cage, Ball and Spring are Stainless Steel. The valve’s maximum working pressure is dependent on housing material, configuration and operating conditions. * Lohm is a measure of flow resistance. See back page for more information.

To install, simply press the valve into a plastic installation hole until the valve is flush minimum with the top of the installation hole. The valve can be installed in either direction, providing forward or reverse flow capabilities. Lee installation tools for each flow orientation are available as follows: Installation Tool Part Number: CCRT0065726S for reverse flow orientation installations, Tool Part Number: CCRT0900180S for forward flow orientation installations. t These valves can be pressed directly into plastics that have sufficient elongation such as Nylon, Polyethylene, Polypropylene,...
