Nicholson Steam Trap

About Nicholson: Nicholson Steam Trap was founded in 1883 by W.H. Nicholson, Sr., who produced a variety of steam specialty products in Wilkes-Barre, Pennsylvania. In the 1930’s, Nicholson developed a wide range of bellows-activated thermostatic traps that are the basis for designs built today. Nicholson's Steam Trap product line varies from highly polished stainless steel sanitary traps to variable orifice float & thermostatic (F&T) traps. Steam traps and condensate pumps are designed for industrial applications such as condensate systems, district heating, main steam systems, process control, and process heating.

Nicholson Products:
Mechanical, orifice, thermostatic, thermodynamic, variable orifice, and clean steam product designs in addition to condensate pumps, piping specialties, and other accessories.

Today, sister companies Spence Engineering and Nicholson Steam Trap provide lines with established industry-leading products that include steam regulators, control valves, safety relief valves, temperature regulators, steam traps, and other steam accessories and solutions.
