Two-Way Valves

2-1/2 to 6-inch Flanged Iron

Body

Description

The Flowrite VF 599 series two-way valves are designed to work with either a pneumatic

or electronic actuator. They are available in both ANSI Class 125 and 250 for normally

closed or normally open action.

Features

• Valve flange face-to-face dimensions meet ISA 75.03 standards

• Direct coupled universal bonnet

• Two flow characteristics (equal percentage or linear)

• Choice of bronze or stainless steel trim

• ANSI Leakage Class IV (0.01% of Cv)

• Cartridge type packing

Application

These Flowrite valves are generally recommended for water, steam, and glycol solutions

to 50%.

• 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 psig and modulating differential pressure up to 50 psi (345 kPa)

Product Numbers

See Table 1 and Table 2.
