Designed with a 4-blade configuration and a clockwise (CW) rotation

this replacement air sensor eliminates the calibration drift often associated with generic alternatives

and discharge temperature excursions

including models like D1EG090N13046A and B1HN090N13025

Using genuine Spence Engineering parts protects the normally closed design and packless construction of the main valve

Siemens Building Technology 599-01121 Valve 319825-402 Designed with a 4-blade configurationThe Siemens Building Technology 599 01121 Valve is a 1 2 inch globe valve body engineered for high precision flow regulation in terminal units and zone control systems. Designed with a normally open configuration and a 1. 6 Cv capacity, this 2 way valve utilizes a modified equal percentage flow characteristic to ensure consistent temperature stabilization across various load demands. The forged brass body and brass trim provide a rugged foundation
