Threaded, compact, low to medium flow <3°F (1.7°C) subcool operation

Two piece threaded body, balanced port, low to medium flow thermostatic sanitary steam trap with 3°F (1.7°C) subcool operation, vertical inlet and outlet threaded connections (for tube fitting applications). Designed specifically for biopharmaceutical and food & beverage pilot and trail scale skid equipment manufacturers for pure steam SIP and loop drainage applications

Up and downstream process vessel: small to medium sized vessels with validated SIP drain lines
Up and downstream process tubing: validated SIP drainage
Filters: small filter validated SIP drainage
Clean steam distribution drainage

Features & Benefits

Low subcooling operation reduces probability of temperature validation faults and resultant SIP delays
Lay-in dimension allows drop in replacement of higher subcool competitive traps
Compact construction of solid 316L barstock
Simple, three piece design with fewer components, cracks and crevices than competitive designs
Self-draining when installed vertically (body outlet side down) either vertical or horizontal connections
