Eaton Model 53BTX Duplex Basket Strainers

Diverting Cartridge Valve Duplex Strainers

The Eaton 53BTX style duplex strainer uses a special ball valve-like diverting cartridge to divert flow from one chamber to another. It is available in cast iron, steel, 316SS and bronze with ¾" to 4" connections.

The 53BTX has a compact, low-profile design that fits where other duplex strainers cannot, while still using full-size strainer baskets and delivering low pressure drop performance. Always compare clean differential pressure for your flow rate and retention size when evaluating brands.

Advantages Over Traditional Plug Valve Designs

Prior designs (like Eaton Model 50) used a tapered plug valve with metal-to-metal sealing. These are prone to leakage and require full strainer replacement when the seat wears. The 53BTX uses replaceable ball valve-style seals for better sealing and longer body life.

The diverting cartridge design makes basket servicing easier and safer by nearly eliminating seepage. This reduces fugitive emissions and cleanup. The lever handle position clearly shows which chamber is in service at all times.

Easy Basket Servicing

No special tools needed. Simply vent the chamber, drain it, lift and swing the cover clear, then remove the basket by its handle.

Cartridge Design Benefits

No manual ball support adjustments required. Low operating torque allows easy lever operation. Double sealing on upper and lower stems prevents leakage. Reinforced polymer seats extend service life. If service is needed, remove four bolts and the cartridge comes out the top — no need to disassemble the entire strainer or remove it from the line.

Flow Guidelines

Suggested maximum flow rates are based on maintaining ≤2 PSI clean pressure drop with the standard perforated basket and minimum 4 ft/sec velocity (maximum resulting velocity ~6 ft/sec).
