Steven Levy Enterprises buys and sells new, unused, and used surplus steam traps, strainers, and transfer valves. Browse our inventory of surplus steam traps, strainers, and transfer valves available for purchase. Steam traps are a type of automatic valve that filters out condensate (i.e. condensed steam) and non-condensable gases such as air without letting steam escape. The purpose of a strainer is to remove or filter particles of matter from fluids or gas. Transfer valves allow water to flow to multiple outlets without shutting off the main feed.
