Three-way Globe Valves

1/2 to 2-inch Bronze Body

Flowrite Globe

Flowrite Three-way Globe Valve.

Description

Designed to work with either pneumatic or electronic
actuators with a 3/4-inch (20 mm) stroke, the Flowrite
Three-way Globe Valves are available in ANSI
Class 250.

Features

• Direct-coupled, universal bonnet

• Equal percentage (NC port) and linear ow (NO port)

characteristics

• Brass or stainless steel trim

• Accepts any 3/4-inch stroke Flowrite pneumatic
or electronic actuator

• Greater than 100:1 rangeability

• 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

Flowrite Three-way Globe Valves are recommended for

mixing applications. The upper port is closed in the normal
stem up, failed position. The lower port is open in the stem
up position.

This valve can also be used for throttling or bypass coil

control application. However, a pump is recommended on
the coil circuit to improve the heat transfer characteristic of
the coil and for freeze protection.

To use this valve as a diverting valve, refer to Technical

Instructions 155-185P25 for limitations or contact your

local representative for more information.
