HI-FLOW™ CONTROL VALVES

VALVES

Globe Valves, Ideal for Steam and Water Flow Control, 1/2˝ to 2-1/2˝ Sizes, 2-Way or 3-Way

2-way with positioner 2-way with air-to-close actuator 2-way with air-to-open actuator

Hi-Flow™ Control Valves are single seated, top or cage guided globe valves -

probably the simplest, from a construction standpoint, yet most versatile control valve in use. The Hi-Flow™ valve can t applications with a smaller size valve since the valve

has a greater ow capacity than most conventional valves of the same size. Coupled with the high ow capacity, the Hi-Flow™ valve maintains a wide rangeability

of 50:1 to insure precise control. Heavy duty Hi-Flow™ valves are ruggedly constructed of the highest quality materials, precision machined, and performance tested to assure years of trouble free service. Standard packing consists of PTFE V-rings and wiper to

minimize friction without leakage at high operating pressures. Available in brass, iron,

or 316 SS body, trim is 316 SS with all welded plug construction to provide superior durability and corrosion resistance.

FEATURES/BENEFITS

• Wide rangeability of 50:1

• Exceptional shut-off and leak rate that meets ANSI/FCI 70-2 Class IV (0.01% of Cv

in the closed position)

• Selectable fail safe condition with Air-to-Raise or Air-to-Lower actuators and Push-to-

Open or Push-to-Close valve bodies

• Linear or equal percentage ow characteristics

• Low ow options of restricted trim or needle plug

• Removable and replaceable seat ring

APPLICATIONS

• Flow control, mixing, or diverting service

• Perfect for steam, water or compatible glycol solutions

HOW TO ORDER

Select model number from model chart or standard product chart and supply maximum upstream pressure, USP.

Use the chart below to aid in the selection of Hi-Flow™ Control Valve. As long as

the maximum upstream pressure (USP) is less than, or equal to, the value listed,

Globe

Valves,

the model shown can be manufactured and calibrated to your specic requirements.

Specify maximum upstream pressure, USP, when ordering.

SPECIFICATIONS VALVE BODY

Service: Compatible liquids, gases, and

steam.

Line Size: 1/2˝ to 2˝. Body Style: 2-way or 3-way globe. End Connections: 1/2˝ to 2˝ female

NPT. Pressure Limit: Iron and bronze body: 250 psi (17.2 bar); 316 SS body: 300 psi (20.7 bar). Wetted Materials: Body material: Iron, bronze, or 316 SS; Trim: 316 SS.

Note: Positioners and current-to-pressure transducers available factory mounted.

Caution: Use of an actuator supply gas other than air can create a hazardous

environment because a small amount of gas continuously vents to atmosphere.
