Spence Engineering
Spence Engineering www.spenceengineering.com
Pressure and Temperature Regulators, Control Valves, Relief Valves, Strainers

In 1925, Paulsen Spence was inspired to design the first normally closed, pilot-operated, diaphragm actuated pressure regulator, the Spence Type ED. The Spence pilot-operated pressure regulator revolutionized the way energy producers supplied low-pressure steam to their customers by providing greatly improved accuracy in pressure control. This feature, as well as dependability and low maintenance, soon made pilot-operated regulators the standard method of pressure reducing and control throughout the steam industry. In recognition of the company's contribution to the nation's war efforts, the Spence Engineering Company received the coveted Army-Navy Award for production efficiency. Paulsen Spence's many inventions (over 60 patents) were: The Type ED packless main valve with external pressure pilot, Type T14 Temperature sensing pilot, Types T124 and T134 combination pressure and temperature control pilots, Type back pressure pilot, Type N differential pressure pilot, Types P and Type F46 pump pressure pilots and various pneumatic pilots. Spence's pilot-operated pressure and temperature regulators were the blueprints for many of the externally pilot-operated regulators manufactured and sold in the world today. Although there have been some changes to the materials and configuration of his inventions, the overall design and operating principals have remained the same since their inception 80 years ago.
