    V100 Series The V100 series product (BLX) is a proven performer and a complete package of pneumatic and electro-pneumatic units. The R100 stackable feedback module can complete a Nema 4X package. This series offers a number of specials such as nickel or Tufram coating. Flexible mounting to rotary or linear actuator is made easy with the “quick connect” couplings.

    V200 Series The V200 series positioner is our newest unit offering the “all-in-one housing” of the standard Nema 4X I/P and internal feedback options. This unit is also available with EX, FF (fail freeze), or 0-10V I/P options. External zero and span make this unit easy to calibrate.



    WestlockICOT LinearICOT Rotary

    Westlock's ICOT™ positioners set the standard for the control of both rotary and linear valves. The ICoT™ provides intelligence for the control valve through a microprocessor-based system. System calibration is performed easily requiring only minutes to accomplish. An on-board microprocessor uses the calibration data to provide accurate operation over the full span of valve travel during normal operation. The ICoT™ positioner has the capability to constantly monitor its own operation. If an error or failure condition occurs, it will be displayed on the local LCD.

    Unlike conventional positioners, the ICoT™ (patent pending) develops accurate valve position feedback without the need for linkages, levers, and rotary or linear seals. Position sensing is performed totally by non-contacting means, permitting use of advanced control strategies where knowledge of valve position is used in predictive and other algorithms.
