Features

The Camflex* II valve is a heavy-duty, automatic-throttling control valve
that incorporates the following features:

• The flangeless body rating is a rugged ANSI Class 600.

• Heavy-duty guide lugs assure quick, positive alignment

during installation.

• A large variety of reduced-trim options are available in all
sizes.

• The triple, over-sized bearing system provides exceptional
plug shaft guiding.

• The shouldered shaft design is utilized.

• The flanged version is available at 1 in. through 12 in. (25 mm

through 300 mm) in 150 or 300 ANSI, and 1 in. through 8 in.
(25 mm through 200 mm) in600 ANSI.

• Separable bonnet design is available.

• Straight through flow pattern provides greater flow

capacities.

• Standard integral extension bonnet allows for a wide range
of fluid temperature applications (-320˚F to 750˚F), (-196˚C to
400˚C).

• The unique self-aligning eccentric rotating plug provides tight
shutoff and low dynamic forces.

• An optional patented differential velocity device (DVD)
separates compressible flowstreams into a high velocity core
and a low velocity envelope flowstream. This provides up to
18 dBA noise attenuation.

• Optional alloy constructions are available.

• The powerful, low-profile, spring-diaphragm actuator

guarantees positive fail-safe action.

• Splined shaft and actuator linkages, combined with low­friction techniques, contribute to reduced deadband and
hysteresis.

• The valve position indicator is large and highly visible.

• The actuator linkage (purge option available) is totally

enclosed).

Notes:

1. It is recommended that the actuator always be mounted as shown above. For other positions, consult your local sales office.

2. Installation is assumed to be in the horizontal pipeline for orientation of the airset and other accessories unless specified on the order.

3. Action and orientation are field reversible without additional parts.

4. Operating efficiencies may vary depending on valve configuration.

5. The above schematic does not reflect every possible body/actuator orientation, but should serve as an effective guide.

Temperature Gradient Across Standard Integral Bonnet

The ability of the Camflex valve to handle a wide range of process fluid
temperatures is due to the long, integrally-cast bonnet. This affords ample
radiation surface to normalize the packing temperatures.

Low flow trims (.036+.07 factor) require use of SVI II AP, or FVP digital positioners.
