Sanitary

Balanced Pressure Thermostatic Steam Trap

Sizes and pipe connections

1⁄2", 3⁄4", 1" and 11⁄2" sanitary clamp ends to ASME BPE.

For other connections please consult Spirax Sarco.

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 a 'clean' environment with protective end caps and

sealed in a protective plastic bag.

Available types
