2.1 Description
The Spirax Sarco BT6-B sanitary balanced pressure thermostatic steam trap is designed to remove
condensate from clean 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 with a minimum of sub-cooling, less than 2
°C from steam saturation temperature at pressures
below 2.5 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.
Options:
-
Fixed bleed to ensure 'FAIL OPEN' operation.
-
Mechanical and electropolishing to 0.375 μm Ra (15 micro-inch Ra,ASME BPE SFV4).
-
For applications requiring closer to steam saturation temperatures, for example, critical SIP
applications, please consult Spirax Sarco.
