About Spence: The Spence Engineering Company was founded in 1926 by Paulsen Spence in Walden, New York. Paulsen Spence developed the original patent for the normally closed external pilot operated packless pressure regulator. This design is the basis for the products offered today. This technology offers the maximum in application and selection flexibility. Spence stands alone in their ability to produce regulators up to 12 inches in cast iron and cast steel. Their pilots are used to control pressure, temperature, differential pressure or back pressure either mechanically or with a pneumatic pilot.

Today, sister companies Nicholson and Spence 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.
