The BPT13T is a brass bodied maintainable balanced pressure steam trap with horizontal in-line connections. It has a unique bypass
and stop valve feature built into the trap which simplifies and reduces the cost of installation. The bypass can be used simply to handle
high start-up loads or to avoid debris collecting in the steam trap, on the commissioning of new systems. The BPT13TGX has an integral
sight tube for indication of operation.
Note: When placing an order always state capsule fill.
Capsule fill and operation
Standard capsules are marked with the letter 'STD' for operation
at approximately 10°C below steam saturation temperature.
Optionally the capsule can be supplied for sub-cooled 'SUB'
operation at approximately 22°C below steam saturation
temperature or a 'NTS' fill capsule for near-to-steam operation
at approximately 4°C below steam saturation temperature.
