Cartridge check valve CCHF series

malehigh-pressurestainless steel

This threadless, cartridge-style, one-way valve is designed for use in high pressure hydraulic systems with operating pressures up to 400 Bar. The valve features The Lee Company’s field-proven locking end, providing secure retention into metal manifolds without the need for threads, O-rings, or sealants. Constructed entirely from stainless steel, it includes a high-quality metal seat for low leakage, repeatable cracking pressure, and long service life. Each valve is 100% functionally tested to ensure performance. - Mounting Configuration: Insert - Into Metal - Diameter: Forward: 5.97 mm, Reverse: 5.47 mm - Lohm Rate: As low as 250 Lohms - Maximum Working Pressure: 400 Bar - Valve Seat Type: Metal to Metal General Performance Characteristic | Forward | Reverse --- | --- | --- Lohm Rate | 320 Lohms | 250 Lohms Leakage at 172 kPa (25 psid) on Air | 10 SCCM (max) | 10 SCCM (max) Maximum Working Pressure, Checked Direction | 400 Bar | 400 Bar Maximum Working Pressure Differential, Flow Direction | 40 Bar | 40 Bar Installation Force | 910 kgf (max) | 625 kgf (max) Materials Component | Material --- | --- Body | 303 Stainless Steel Cage | 416 Stainless Steel Pin | 416 Stainless Steel Spring | 302 Stainless Steel Ball | 440C Stainless Steel Part Numbers & Specifications Part Number | Flow Direction | Lohm Rate | Cracking Pressure | Installation Hole Drawing Number | Diameter (mm) | Maximum Installation Force (kgf) --- | --- | --- | --- | --- | --- | --- CCHF6010000S | Forward | 320 Lohms | 0 kPa (No Spring) | 1INST049203S | 5.97 | 910 CCHF6010014S | Forward | 320 Lohms | 14 ± 5 kPa (2 ± 0.7 psid) | 1INST049203S | 5.97 | 910 CCHF6010040S | Forward | 320 Lohms | 40 ± 30 kPa (6 ± 4.4 psid) | 1INST049203S | 5.97 | 910 CCHR5510000S | Reverse | 250 Lohms | 0 kPa (No Spring) | 1INST002604S | 5.47 | 625 CCHR5510014S | Reverse | 250 Lohms | 14 ± 5 kPa (2 ± 0.7 psid) | 1INST002604S | 5.47 | 625 CCHR5510040S | Reverse | 250 Lohms | 40 ± 30 kPa (6 ± 4.4 psid) | 1INST002604S | 5.47 | 625 Replacement Parts & Accessories Part Number | Description --- | --- CCRT0051078S | Forward 400 Bar Installation Tool CCRT0900120S | Reverse 400 Bar Installation Tool - Flow Curves, Cross Section Views, Dimensional Views, Installation Hole Details: See secondary images for detailed diagrams and technical drawings.
