Camﬂex II Eccentric Plug

Rotary Control Valve

The Camﬂex Principle

3:1 Multiplication of Forces

Conventional Valve Design

1:1 Ratio of Forces Requires Large Actuator

The Camflex plug makes no contact with the seat until it rotates into its full closed position.

Tackling Key Challenges

Reliable Long-Term Shutoff

With its eccentric rotating valve plug, the Camflex II

Eccentric Plug Rotary Control Valve reduces two common

valve shortcomings: excessive seal ring friction inherent

in ball valves and high actuator forces required for tight

shutoff of either conventional globe valves or butterfly

valves.

Because of its unique seating action, the Camflex plug

makes no contact with the seat until it rotates into its

full closed position. Once seating occurs, continued shaft

rotation causes the plug arm to flex, forcing the plug into

deeper contact with the seat ensuring consistent tight

shutoff. This reliable seating method reduces wear from

rubbing contact, and the tight shutoff performance greatly

reduces the possibility of clearance flow-induced wear or

erosion. Camflex seating mechanics and resulting long-

term reliable shutoff offer the following benefits:

• Reduced rubbing – greatly reduced friction and wear

• Improved uptime – extended maintenance cycles

• Reduced unplanned outages and production loss

By combining eccentric plug action with a long actuation

lever, this valve achieves a 3:1 force multiplication. This

means that only one-third of the force required to stroke a

conventional single-seated globe valve is required for the

Camflex actuator to stroke against a given pressure drop.

• Smaller actuator size

• Faster response speed

• Improved control performance

Environmental Emissions

Compliance

Why pay extra to comply with current environmental

emissions requirements? Unlike some control valves that

require expensive specialized packing systems to satisfy

low emission requirements, Camflex II Eccentric Plug

Rotary Control Valves come standard with GE’s Masoneilan

EF* seal (Emissions Free seal) technology.

• Standard at no extra cost

• Satisfies global low emissions standards requirements

• Simple and reliable with long life
