Stainless Steel

Clean Steam Trap

Description

The Spirax Sarco BTS7 is a sealed thermostatic steam trap designed to remove condensate from clean steam systems with minimal

backing up. Applications include sterile steam barriers, process vessels and CIP/SIP systems. Manufactured in 316L stainless steel

with minimal crevises, it is self-draining and operates close to steam temperature. Traps are individually packaged with protective end

caps and sealed in a polythene bag.

Options

Fixed bleed to ensure fail open operation.

Special connections to suit most piping systems.

Standards

The BTS7 has been designed and built in general accordance with ASME BPE. It also complies with the requirements of the European

Pressure Equipment Directive 97 / 23 / EC. All wetted parts of this trap are manufactured from FDA approved materials.

Certification

This product is available with a manufacturer's Typical Test Report.

Note: All certification/inspection requirements must be stated at the time of order placement.
