• Valve ange face-to-face dimensions meet
ANSI/ISA S75.03 standards
• Direct-coupled, universal bonnet
• Bronze or stainless steel trim
• Standard- or high-temperature packing
• Close-off up to 250 psi
• Fully serviceable
• Greater than 100:1 rangeability
• Equal percentage or linear ow characteristics
• 2-1/2 and 3-inch sizes available with 3/4-inch
stroke only
• 4-, 5-, 6-inch are available with a 1-1/2-inch stroke
• ANSI Leakage Class IV (0.01% of Cv)
• Cartridge-type packing for easy service
• Orderable as a valve only or as a complete
valve/actuator assembly
Applications
The Flowrite Two-way valves are recommended for water,
steam, and glycol solutions up to 50 percent. Additional
specications include the following:
• Water inlet pressures up to ANSI 125 and ANSI 250
cast iron body rating
• Water modulating differential pressure up to 25 psi
(172 kPa) for bronze trim and 50 psi (345 kPa) for
stainless steel trim
• Steam inlet to 100 psi with modulating differential
pressure up to 50 psi (345 kPa)
