product data sheet The Lee Company’s Industrial MicroHydraulics Group (IMH) introduces the newest addition to our line of miniature, threadless, cartridge-style check valves specifically designed for installation into metal manifolds. Our new 558 LC Series Insert ChekTM Valve offers more than a 67% increase in flow capacity over the existing 558 series check valve. Designed for reliable operation, the new valve features robust, stainless steel construction, providing compatibility with a wide range of fluids and gases. A high-quality metal to metal seat provides low leakage and highly repeatable cracking pressures. This robust design and 100% functional testing ensures consistent long-term performance. ■ Integral locking end - No o-rings or sealants to fail ■ Leak tight - Efficient system performance ■ Metal to metal seating - Provides high reliability - Long life ■ Positive ball stop - Infinite spring life - Stable performance ■ 100% tested - Eliminates rework, reducing internal costs - Enhances customer's product quality Simple to install, the new check valve uses Lee’s field-proven insert principle that provides secure retention and eliminates the need for threads, o-rings or inhouse designs. To install, simply insert the check valve into a drilled installation hole and drive the expansion pin flush to seal and lock the valve in place. The new 558 LC Chek Valve’s compact size, superior performance, and ease of installation make it ideal for high volume applications in automotive, off-road, and other industrial hydraulic systems. CHEK VALVE FLOW DIRECTION CHECKED DIRECTION *LOA before installation. All dimensions in millimeters, except where noted. Lohm Rate: 150 Lohms* Leakage: 20 sccm/min. (max.) @172 kPa (25 psid) on air 1 Drop/min.

Drive the expander The installation tool can bottom on the insert body with no con- pin flush to within 0.25mm (0.010") above flush of the check sequence. Lee Installation Tool part number CCRT0900120S is valve body. Use a maximum installation force of 625 KgF (1,380 available. lbs. force). LOHM LAWS LOHMS LAWS (liquids) Every engineer will be interested in our simple system of defining the fluid resistance of Lee hydraulic components. Just as the OHM is used in the electrical industry, we find that we can use a...
