SpxFlow 504 Snap-Trap Float-Operated Automatic Condensate Drain

The SpxFlow 504 Snap-Trap is a float-operated automatic condensate drain designed for efficient removal of condensate from compressed air systems. This mechanical drain valve automatically discharges water, oil, and oil/water emulsions from separators, receiver tanks, dryers, filters, and drip legs without requiring electrical connections.

Key Features:

• Float-operated mechanism activates automatically when liquid accumulates in the system
• Maximum working pressure up to 175 PSIG (12.3 bar)
• 1/2 inch NPT top connection for easy installation
• Economical design suitable for light to medium duty applications
• No electrical connection required for operation
• Durable construction for reliable performance in industrial environments

The 504 Snap-Trap drain operates as a normally closed valve that opens when the internal float rises due to accumulated condensate, effectively discharging liquid and debris from the system. This automatic operation ensures consistent condensate management without manual intervention, making it ideal for compressed air applications in industrial settings.

Replacement Information: This unit serves as a replacement for Hankison part numbers HKN-0503 and HKN-503. Compatible with SPX part number 6001788.
