High-Pressure Bimetallic Steam Traps

• Sizes: 1/2" to 2" [15mm to 50mm]
• Maximum operating pressure: 1,595 psig [110barg]
• Materials: Carbon steel, stainless steel, and alloy steel

OPERATING PRINCIPLE

is based on a balance between the steam force (pressure dependant), trying to open the discharge valve, and the opposing bi-metal force (temperature dependant), which tends to close it. The trap is adjusted so that at satuarated steam temperature the bi-metal force will prevail, while with undercooled condensate and air, the force of pressure will prevail and open the valve. For a well designed trap, the required undercooling should be the minimum possible
throughout the designed pressure range. Being the steam force a curve while the bi.metal force a straight line, an additional compensating spring will break the straight line to make it follow the curve of steam more closely, making field adjustment unnecessary.
