Spence – A leader in Steam Regulators

Spence Engineering is known as the leader in the steam regulator and flow control industry. Founded in 1926 by Paulsen Spence in Walden, New York, the Spence Engineering Company has many years of experience designing and building regulators. They are responsible for developing and patenting the first normally closed – external pilot operated – packless pressure regulator. The original design is the basis of the modern hydronic products they now offer.

Spence is one of the few manufacturers who are able to produce regulators up to 12 inches in cast iron and steel. Their technologically advanced regulators are found in the heating systems of industrial plants, buildings of all kinds, institutions and district heating systems.

Offering a maximum in application and selection flexibility, their pilots are used extensively to mechanically or pneumatically control:

  • Pressure
  • Temperature
  • Differential Pressure
  • Back Pressure
