Flowrite™ 599 Series, 2-Way Valves, 1/2 to 2-Inch,
Threaded, ANSI Class 250, Bronze Body
Siemens Industry, Inc.
Description
The Flowrite 599 Series two-way valve bodies, ANSI 250,
work with a Flowrite series actuator with a 3/4-inch
(20 mm) stroke. Typical applications include control of hot
or chilled water, 50% water-glycol solutions, or steam.
Product Numbers
Use the product numbers in the tables to order the valve
and 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.
Features
• ANSI Leakage Class IV (0.01% of Cv).
• Normally-open and normally-closed configurations.
• Cartridge-type packing.
• Equal percentage flow characteristics with either
brass or stainless steel trim.
• Linear flow characteristic with stainless steel trim.
• High temperature packing available on linear valves.
• Direct-coupled universal bonnet.
Typical Specifications
Automatic control valves shall have NPT threaded type
fittings, 1/2 through 2 inch (15 through 50 mm) sizes, and
shall be ANSI 250 rated to withstand the pressures and
temperatures encountered.
Valves shall have metal-to-metal seats, stainless steel
stems, and ethylene propylene O-ring packing.
Valves shall be ANSI Leakage Class IV (0.01% of Cv).
Valves shall have a 100:1 rangeability or better.
