Applications include sterile steam barriers, process vessels and CIP/SIP systems. Manufactured in 316L stainless steel with minimal crevices, it is self-draining and operates close to steam temperature. Traps are individually packaged with protective end caps and sealed in a polythene bag.
The BTM7 has been designed 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. The O-Ring Seal complies with USP Class VI and FDA CFR title 21, Paragraph 177, Section 2600.
The trap is designed for installation in vertical lines with the flow downward to ensure self-draining operation. Do not expose the element to superheat conditions since over-expansion may result. Suitable isolation valves must be installed to allow for safe maintenance/replacement.
