SPX Hankison 505 Trip-L-Trap Automatic Pneumatic Condensate Drain Valve

SKU: 505
Part #: 505

SPX Flow / Hankison OEM 505 Trip-L-Trap Pneumatic Condensate Drain

Hankison’s level actuated, pneumatically operated condensate drains automatically discharge water, oil, and oil/water emulsions from separators, receiver tanks, dryers, filters, after-coolers and drip legs. Each drain is engineered to reduce system downtime by eliminating the need to manually drain compressed air lines and equipment.

The 505 drain is rated to handle up to 300psi. The inlet connection is on the top of the drain and connects via a 3/4" NPT connection. The drain outlet is a 1/4" NPT connection.

Unlike simple float operated drains, these drains feature an air powered piston for positive opening and closing of the discharge port. This operation prevents clogging of the compressed air system while the baffle protects the operating mechanism from contaminants. The magnetic action lengthens time between cycles and prevents any external vibration from causing unnecessary discharge.

The Trip-L-Trap® Series automatic condensate drains are designed for versatile installation, reliable performance and economical operation with features available to protect your compressed air system.

The 505 series Trip-L-Trap drain is designed for heavy duty service and applications with heavily contaminated condensate output.
