NICHOLSON
Frequently asked questions
Common questions about NICHOLSON from 3G Electric.
What materials are used in Nicholson steam traps?
Nicholson steam traps are available in cast iron, stainless steel, and bronze constructions. Cast iron is common for the body in many models, such as the FTN series, while stainless steel is used for floats and internal components to resist corrosion. Bronze options are available for specific applications requiring non-ferrous materials. The choice depends on the operating environment, pressure, and temperature requirements.
What is the difference between Nicholson FTN and NFT 250 series steam traps?
The Nicholson FTN series includes float and thermostatic steam traps in C-pattern and H-pattern body styles, designed for horizontal installation with capacities up to 10,900 lb/hr and pressures up to 75 psi. The NFT 250 series is an in-line float and thermostatic trap with a compact design, rated for pressures up to 250 psi and capacities up to 2,450 lb/hr. The FTN series suits larger systems, while the NFT 250 is for higher-pressure, smaller-footprint applications.
Can Nicholson radiator valves be used for both hot water and steam systems?
Yes, the Nicholson N25-FO radiator valve is designed for both hot water and steam systems. It features a temperature-sensitive actuation and an angle body style made from brass and stainless steel, with a 3/4 in NPT connection and a 25 psi rating. This makes it suitable for controlling heat output in radiators in commercial and industrial buildings.
What body patterns are available for Nicholson float and thermostatic steam traps?
Nicholson offers float and thermostatic steam traps in three body patterns: in-line, C-pattern, and H-pattern. In-line traps have connections aligned on the same axis, C-pattern traps have connections at 90 degrees, and H-pattern traps have connections offset for compact installation. Each pattern accommodates different piping configurations and space constraints.
What is the maximum operating temperature for Nicholson steam traps?
Nicholson steam traps, including the FTN and NFT 250 series, have a maximum operating temperature of 450°F. This temperature rating applies to the cast iron body and stainless steel internals, ensuring reliable performance in typical steam system conditions up to that limit.
