Flowrite™ 599 Series Valves, 2-1/2 to 6-Inch,
Flanged, ANSI Class 125, Iron Body
Siemens Industry, Inc.
Description
The Flowrite 599 Series two-way and three-way flanged
iron bodies are designed to work with a Flowrite series
actuator with a 3/4-inch (20 mm) or 1-1/2 inch (40 mm)
stroke. They are available in ANSI Class 125 for normally
open, normally closed or three-way action. Typical
applications include control of hot or chilled water, 50%
water-glycol solutions or steam.
Features
• ANSI Class IV leakage (≤ 0.01% of Cv).
• Two-way normally open and normally closed
configurations.
• Cartridge-type packing.
• Two-way equal-percentage flow characteristic valves
with either bronze or stainless steel trim.
• Two-way linear flow characteristic valves with
stainless steel trim.
• Three-way valves with either bronze or stainless steel
trim.
• High temperature packing available on two-way linear
valves.
Product Numbers
Use the product numbers in the tables to order the valve
and the actuator assembled together. The product number
consists of a 3-digit prefix code, a hyphen, and a 5-digit
suffix code. The prefix specifies an actuator. The suffix
specifies the valve body.
Typical Specifications
Automatic control valves shall have flanged connections,
2-1/2 inch through 6-inch (65 through 150 mm) sizes, and
shall be ANSI 125 rated to withstand the pressures and
temperatures encountered.
Valves shall have metal-to-metal seats, stainless steel
stems, and double (EPDM) O-rings or Teflon
®
V-rings with
single O-ring packing.
