Description
Overview
The ControlAir Type 2000 CA2000 P/P Pneumatic Valve Positioner provides stable and accurate positioning of rotary and linear pneumatic control valves. Designed for applications using a standard 3-15 psig pneumatic input signal, the CA2000 continuously controls actuator pressure to help the valve accurately follow the commanded position.
The Type 2000 uses a force-balanced operating principle designed for simple calibration, maintenance, and field service. An external zero adjustment simplifies setup, while a high-gain pilot valve provides quick and accurate valve and actuator response. The positioner is also designed to be insensitive to vibration, mounting position, and shock, supporting reliable operation in demanding industrial environments.
Available for both rotary and linear valve applications, the CA2000 combines precise pneumatic positioning with high flow capacity, low hysteresis, and excellent repeatability. Its rugged NEMA 4X / IP65 aluminum enclosure with polyester epoxy finish provides protection for industrial process installations, while the modular Type 2000 design supports multiple mounting, spindle, cam, and indication configurations.

Performance Characteristics
The CA2000 uses a pneumatic input signal to position the valve actuator through a force-balanced mechanical feedback system. As the pneumatic input signal changes, the positioner adjusts its output pressure to move the actuator. Mechanical feedback from the valve or actuator returns to the positioner until the commanded input and actual valve position are balanced.
This closed-loop pneumatic positioning provides better control of actual valve position than actuator pressure alone. The CA2000 delivers published linearity error of less than 0.7% of full scale, hysteresis below 0.4% of full scale, and repeatability below 0.3% of full scale.
Its high-gain pilot valve also provides substantial pneumatic flow capacity for responsive actuator movement. Flow increases from 9.5 SCFM at 29 psig supply to 47.1 SCFM at 145 psig supply, supporting a range of pneumatic valve actuator sizes.

How to Select the Right Configuration
Selecting the proper CA2000 configuration depends on valve motion, actuator mounting arrangement, spindle type, required valve travel or rotation, local position indication, and any desired position feedback or switch options.
Select Rotary or Linear Motion
- R = Rotary
- L = Linear
The Type 2000 specification sheet specifically identifies the CA2000 as available for both rotary and linear valve applications.
Select the Indicator
- N = None – Standard for linear configurations
- A = Arrow – Standard for rotary configurations
- D = Dome – Optional raised position indicator
Select the Spindle
- 0 = Namur – Rotary
- 1 = Standard – Linear
- 2 = 3/8″ Square
- 3 = 1/2″ Square
Select the Cam
- C1 = 90°/180° – Standard rotary
- C2 = 45°/90°
- C3 = 30°/60° – Standard linear
Consider Feedback and Switch Requirements
For applicable CA2000 rotary configurations, factory-installed options include:
- F = 4-20 mA position feedback
- S = Two SPDT mechanical switches
- FS = 4-20 mA feedback plus mechanical switches
The ordering information limits these factory-installed feedback and switch options to applicable CA2000 and CA2005 rotary configurations.
