Introduction
BT series clean steam traps are designed for draining clean and pure systems. They can be used in sterilizers, main drains, CIP/SIP systems and process vessels. The valve body is made of 316L stainless steel with a high internal surface finish and a 150° tilted seat to ensure self-drainage.
| Features | Materials | Restrictions | |
| Rapid air discharge ensures quick start-up and continuous operation. Seamless design inhibits bacterial accumulation to the greatest extent. The valve seat is designed to be inclined 150 degrees to ensure self-drainage. The inner surface polishing degree can reach Ra0.8um. | • Valve body, valve cover: F316L • Valve seat: F316 • Liquid capsule: 316 • Clamp: 316L • Sealing ring: sanitary grade fluororubber | Design pressure (PMA): • SM45: 110 bar • SM65: 160 bar | Maximum operating pressure (PMO) @ maximum operating temperature (TMO) • SM45 type: 45bar @ 450°C • SM65 type: 65bar @ 475°C |
| How it works |
| The working element of the BT series is a stainless steel bladder (thermostatic element). When the machine is cold or started, the bladder (temperature sensing element) is in a relaxed state, and the valve core and valve seat are fully open to discharge a large amount of air and condensed water. When the system temperature approaches the saturated steam temperature, the liquid in the bladder expands (the thermostatic element is deformed by heat), pushing the valve core to the valve seat to close and prevent steam leakage. The closing temperature is close to the saturated steam temperature, ensuring effective drainage of the system. |

Installation Tips
The BT system is designed to be installed vertically with the flow direction downward to ensure self-drainage of the valve body. Please check the flow direction arrow on the valve body during installation. A cooling pipe must be left upstream to prevent condensate from accumulating on the process equipment during normal operation. The temperature sensing element cannot be placed in an overheated condition.
