metal comprising two or more metallic layers with different coefficients of expansion, which changes curvature when subjected to heat. Velan steam traps use a bimetal of high tensile strength, stable at high temperature with deflection limited to 600°F (315°C) to prevent over-stressing in super-heated steam service. what is bimetal? ●● Bimetal is a composite Deection & Pull The Original “multi-segmented” bimetal principle actuates Velan steam traps THE CLOSING FORCE OF THE BIMETALLIC ELEMENTs Follows the SATURATED STEAM curve Chart 1 illustrates the truly universal operating principle...

principles of operation The Velan patented bimetal principle as applied to meet various requirements universal steam trap principle Chart 2 The patented multi-element principle. bar.g psi.g See page 4 for more details. Element closing forces Steam pressure closing force developed at saturated temperature in relation to the line pressure tending to open the valve. The gradual increase in force, following the steam curve, is a function of the patented segmentation principle of the element. The delicate balance of opening and closing forces exists in all pressure ranges such as 0-200, 0-350,...

how it works The four purpose valve and its function in the Velan universal bimetallic steam trap fast warm up positive trapping The discharge valve is open, allowing air and cold water to be discharged rapidly. The period of waiting to start a process is reduced to minutes—there is no air binding, water-logging, or steam locking to delay equipment warm up. Incoming steam causes the bimetal to deflect. This thermal pull of the bimetal element acts on the valve stem, overcoming the steam pressure closing the valve. The ball valve is pulled tightly on to its seat, preventing weeping and loss...

how it works The four purpose valve and its function in the Velan piston operated and the monovalve float bimetallic steam trap piston operated monovalve Float bimetallic fast warm up Cool air and condensate from the system is discharged through the large main valve orifice actuated by the piston, which is held open by it’s own weight when cold. As line pressure builds up, pressure above the piston keeps the valve open at maximum discharge until the system is completely purged of air and condensate. Clearing air and moisture from a cold system rapidly reduces warm up time and increases...

VELAN forged bimetallic cage Unit steam traps Cage unit on type ts, tsf, and sf Cage Unit The advanced cage unit design in Velan steam traps combines a bimetal element, hardened Rc 58 min. ball valve, and a CoCr alloy hardfaced seat area all in one factory-tested assembly. SERVICE: 2 MINUTES TO REPLACE CAGE UNIT Replacement of all wearing parts can be achieved in less than two minutes, with the trap remaining in-line. ts, tsf, and sf Design Features ●● Forged valve body and cover offer the advantages of high strength, structural integrity and reliability that make it an ideal choice for...
