Spence Engineering Pressure & Temperature Controls

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, externally 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 self-contained regulators up to twelve (12") inch in size that require NO external power source in both Cast Iron & Cast Steel. Their pilots are used to control pressure, temperature, differential & backpressure either mechanically or with pneumatics.

Spence Engineering is a widely recognized leader in the steam regulator and flow control field. Spence regulators are used extensively for heating systems, institutions and district heating systems, as well as major industrial plants.

In 1984 Spence was aquired by Watts Industries. The company continued to grow and develop new steam and fluid specialty products. A new line of pneumatic control valves was introduced in 1986.

In 1990, Spence became certified by the ASME for the assembly and setting of safety & relief valves maufactured by a Spence sister company in Canada. Spence also aquired the Nicholson Steam Trap plant and moved it to Walden NY in 1994. Spence continued its aggressive product development with the addition of the Free Float Steam Trap and Pressure Driven Condensate Pumps. In 1996 Watts moved manufacturing of Safety & Relief Valves to Spence Engineering's state of the art plant in Walden, NY. Spence is now an ASME certified manufacturer of bronze and cast iron safety & relief valves.

Spence Engineering continues to focus their attention on providing single source steam specialty products and solutions for the use, regulation, control & relief of steam and fluids for the institutional and industrial marketplace. Their growth efforts are to expand the already comprehensive product capabilities to reach new developing markets.
