Key Features
• Standardized Fit – Interchangeable with Parker 6600, Faster ANV, Aeroquip 5600, and Hansen HA series.
• Robust Valve Design – Internal poppet valve mechanism provides automatic shut-off during disconnection.
• Corrosion Resistance – SUS304 or SUS316 stainless steel available, ideal for demanding applications.
• High-Flow 1” Size – Handles larger volumes and pressure levels in 1” hydraulic systems.
• Multiple Thread Options – G (BSP), NPT, and BSPP threads available upon request.
• Seal Options – Standard NBR seals, with FKM (Viton) or EPDM optional.
Technical Construction
The CB-SPM-10F features a female socket body with an integrated knurled sleeve for manual connection and disconnection. Internally, a spring-loaded poppet valve ensures secure shut-off to prevent fluid loss and contamination during uncoupling.
This model supports working pressures up to 3000 PSI (depending on system size), and is suitable for both static and mobile systems requiring quick maintenance and low downtime.
