Features

• Disc-Type Non-Return Valve: Opens fully in the direction of flow and closes quickly when flow reverses.
• Compact and Rugged: Ideal for tight spaces and harsh industrial environments.
• Corrosion Resistance: Stainless steel internals and plated body enhance durability.
• Flexible Mounting: Can be installed in any orientation and close-coupled with other valves.
• Application Note: Not recommended for pulsating or partial loads (e.g., compressor discharge); for such cases, Hansen recommends the HCK1 piston-type check valves
