599 Series 3-Way Ball Valves  
  Siemens Industry, Inc. 
Description 
The 599 Series three-way Ball Valves are coupled with 
OpenAir
®
 actuators to provide equal percentage flow control in 
either mixing or diverting applications. The Ball Valves are 
1/4-turn rotary control valves and are available in 1/2-inch to 
2-inch line sizes. 
Product Numbers 
Use the product numbers in Table 1 or Table 2 to order the 
valve and the actuator assembled together. The product 
number consists of a 4-digit prefix code, a hyphen, and a 5- or 
6-digit suffix code. The prefix specifies an actuator. The suffix 
specifies the valve body. 
Features 
•  ANSI 250 valve body rating. 
•  Available in either chrome-plated brass ball/brass stem or 
316 stainless steel ball and stem 
•  May be used as either mixing or diverting valves 
•  Shutoff up to 200 psi 
•  Universal mounting plate 
•  Blow-out proof stem withstands high pressure 
•  Actuator and plate can be rotated 
•  Standoffs provide a thermal barrier between the actuator 
and the mounting plate 
•  Operating handle can manually operate valve. 
•  All ball valve actuators include integral conduit adapters.
