The Spirax Sarco BT6-B Series High or Low Capacity Sanitary Balance Pressure Thermostatic Steam Trap is designed to remove condensate from clean and pure steam applications with minimal condensate retention. Constructed of 316L Stainless Steel with a crevice free body, this trap features 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 3.6° Fahrenheit (2° Celsius) from steam saturation temperature at pressures below 36 psig (2.5 barg) for typical operating conditions. Operating performance influenced 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.

Applications:
• Sterile Steam Barriers
• Block and Bleed Installations
• Mains Drainage
• CIP/SIP of Vessels and Reactors
• Process Lines

Installation:
Ideally installed in vertical lines with the flow downwards so that the body is self-draining. Refer to the flow arrow on the unit for correct orientation. Fittings and pipe clamps are NOT included. A cooling leg should be installed along with this to avoid condensate back-up into process equipment under normal operating conditions. Do not expose the capsule element to superheat conditions. Handle all components carefully to avoid damage to surfaces.

Sample Specification:
Balanced pressure steam traps with in-line connections shall be designed for specific use in sanitary/hygienic applications. The trap shall be suitable for CIP/SIP systems requiring large cold condensate discharge capacities at low pressures typically encountered at the start of sterilizing cycles. Traps must discharge at least 2400 lb/h (1100 kg/h) of cold condensate with 3'3" (1.4 psi) water column differential. Traps must open approximately 3.6° Fahrenheit (2° Celsius) below steam temperature at discharge pressures of 36 psig (2.5 barg) or less for minimal sub-cooling of condensate, and typical condensate back up shall be 6" (150mm) or less at all times. The trap shall have a sanitary safety body clamp and housing design to prevent accidental disassembly and incorrect reassembly. The trap shall be self-draining with at least a 15° angled seat to ensure full drainability when mounted vertically. Construction shall be of 100% 316L, including bodies, internals and related systems. The maximum allowable internal surface finish for wetted parts shall be 15 µ-inch Ra (0.375 µm)and 40 µ-inch Ra (1 µm) for external surfaces. Traps must comply fully with ASME BPE and the European PED 97/23/EC, and all seals must comply with FDA CFR title 21, part 177, section 1550 and USP24 class VI.
