Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-P180-31) supplied with the product. Installation note The BT6-B is designed to be installed in vertical lines with the flow downwards so that the body is self-draining. Check the flow arrow on the body for correct orientation. Fittings and pipe clamps are not supplied. Installation should include a suitable cooling leg 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. Operation The operation relies on a stainless steel capsule that is filled with a WFI temperature sensing fluid. During cold or start-up conditions the capsule will be fully open allowing large volumes of air, condensate and/or CIP fluid to be drained. As the system approaches steam temperature the fluid in the capsule expands and the valve closes the trap to prevent live steam loss. This closure occurs very close to steam temperature to ensure efficient drainage of the system.
