Steam Trap Valve

Steam Trap Valve

Steam Trap Valve is a device used to discharge condensate and non condensable gases with a negligible consumption or loss of live steam.

The functions of Steam Trap Valve are to eliminate the condensation water quickly, to prevent steam leakage, to exclude air and other non-condensable gas, to prevent water hammer and prevent the use of equipment reduces the efficiency of steam, the steam used to prevent corrosion inside the device, to prevent the steam using equipment damage.

Most Steam Trap Valves are nothing more than automatic valves. They open, close or modulate automatically. Others are based on turbulent 2-phase flows to obstruct the steam flow.

Steam traps work best when sized specifically for the application they are used on. Generally it is better to over size as they will still discharge condensate when present and close when steam is present, however an over sized steam trap will wear quickly, waste energy (use steam), and if drastically over sized can cause process issues.

Steam Trap Valves can be split into four major types: Mechanical traps, Temperature traps, Thermodynamic (TD) traps and Venturi (orifice) traps.
