BT6-B and BT6-B Food+

Sanitary Balanced Pressure Thermostatic Steam Trap

BT6-B and BT6-B Food+ Sanitary Balanced Pressure Thermostatic Steam Trap

The Spirax Sarco BT6-B sanitary balanced pressure thermostatic steam trap is designed to remove condensate from clean (ChemicalFree) and pure steam applications with minimal condensate retention.
Applications include sterile steam barriers, block and bleed installations, mains drainage and CIP/SIP of vessels and reactors and process lines.
Manufactured in 316L, the crevice free body design of the BT6-B incorporates a 15° angled seat to ensure full drainability.
The standard element is extremely sensitive to changes in condensate temperature and is designed to open within 2 °C nominal sub-cooling of steam saturation temperature at 50 mm above the trap and at pressures below 2.4 bar g for typical operating conditions.
Exact operating performance may be affected by operating pressure, installation and ambient conditions.
Each trap is individually packaged within an ISO CLASS 7 ‘clean’ environment with protective end caps and sealed in a protective plastic bag.
