Spence Engineering

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.

Spence Engineering continues to focus their attention on providing single source steam
specialty products for regulating and control of steam and fluids for the insti tutional and
industrial marketplace. Their growth efforts are to expand the already comprehensive
product capabilities to reach new developing markets.
