Camflex II Universal Control Valve
Spring-Diaphragm Actuator Provides Smooth Control
4
Spring-Diaphragm Actuator with Rolling Diaphragm
(Constant Area) Offers Superior Linear Control
Open Actuator Linkage
- Exposed to environment
- Contaminants can affect performance
4
Fully Enclosed Actuator Linkage
- Protected from environment
Positioner Mounting Uses Complex Linkage
- Increased risk of lost motion, adjustment errors
- Performance is installation dependent
4
Direct, Linkageless Positioner Mounting
- Positioner directly connected to valve shaft
- No lost motion
- Consistent long-term performance across all installations
Sliding Stem Reduces Packing Durability
- Increased wear
- Higher friction
- Contaminants can be dragged through packing
- Expensive optional systems required for low-emission compliance
4
Rotary Shaft Motion Provides Increased Packing Life
- Low wear
- Low friction
- Rotating motion prevents contaminants from being dragged through packing
- Standard EF
*
Seal low emission packing system
Gasketed Pressure Boundary Joint
- Risk of leakage
- Multiple gaskets and shims depending on trim size – Qty. 3 to 5
4
No Gasketed Joints / No Gaskets / No Shims
Linear Seating Motion
4
Linear Seating Motion Due to Cam Action of Plug
1:1 Ratio of Unbalance Force
- Large unbalanced area requires balance seals that limit tight shut off
- Larger required actuator slows dynamic performance
4
3:1 Force Amplification Reduces Unbalance Force
- Lower force reduces required actuator size
- Smaller actuator volume area improves dynamic performance for faster system response
Cage Guiding
- Guide surface in flow stream
- Fluid contaminants can damage guiding surfaces
- Not trash tolerant
4
Heavy Triple Guiding
- Guide surfaces out of flow stream
- Fluid contaminants do not impinge on guides
- Trash tolerant

Typical Weight (2” size): 133 lbs (59 kg)
- Even in small sizes, some valve styles may require use of lifting devices during
installation and removal
4
Weight (2” size): 45 lbs (20 kg)
- Camflex’s lower weight makes handling a breeze and the low profile
allows installation into tight areas with low overhead room
