ECOFLOW Threaded Venturi Orifice Steam trap

The new ECOFLOW Venturi orifice steam trap range is designed to meet the rigorous requirements demanded by today’s industrial plant users. Developed on a modular concept, the trap encompasses a wide range of capacities. These include minimal condensate flow requirements, on line drainage and trace heating systems, through to the high flow volumes and variable loads of process heating applications. The trap’s unique innovative design allows for both these conditions to be serviced within the same threaded or socket welded body.

Threaded Version - Type EFK-SC & EFG-SC

ECOFLOW’s threaded or socket welded trap incorporates the first Venturi steam trap design that is integral with the cast housing and delivers permanent solutions for all steam trapping requirements. The Venturi orifice technology forms part of your total steam system pipework. With no moving parts it is a permanent part of the steam system and will never need replacement.


  • Unique modular design for low and high condensate flow
  • Multiple nozzle configurations designed for optimum efficiency at operating point
  • Fully cast housing with optional BSP threaded or socket weld connections
  • Flexible filtration options, increased secondary filtration available for contaminated systems
  • Graphite seals, metal bonded and fully encapsulated to eliminate leakages
  • All BSP thread dimensions in accordance with ISO 7-1:1994
  • In-line constructions allows for removal and cleaning of filters and nozzles
