Douglas DF Thermodynamic Steam Traps

This type of trap uses steam dynamic energy to close the discharge orifice. A disc closes both the inlet and outlet orifice. Condensate can lift the disc and be discharge , but when steam is formed its dynamic energy will create a low pressure area ( Bernulli Law ) under the disc which draws it towards the seat.

Reduced dimension and wheigt simple and reliable. It discharges air. It withstands waterhammer. Condensate discharge is intermittent. Some loss of live steam.
