  • Pneumatic and electro-pneumatic positioners AV1 & AV2 Type AV1 & AV2 Characterizable Positioners are control devices that satisfy a wide range of applications. They provide fast, sensitive, and accurate positioning of pneumatic single or double-acting, linear or rotary motion actuators. Overview: A mechanical connection from the actuator to a position feedback cam in the positioner establishes actual position. Three characterized segments on one cam provide application flexibility by establishing various relationships between input signal and actuator position. The relationships provided by the segments are square root, linear, and square. The Type AV1 positioner receives an external pneumatic signal and converts it to a pneumatic output. This output produces the motive force that positions the power actuator. The type AV2 positioner receives an external 4-20mA signal and converts it to a pneumatic output. This output produces the motive force that positions the power actuator Data:
    • Compact rugged design
    • High vibration and shock environments
    • Fast, accurate calibration
    • Single or double-acting without additional hardware
    • Vent design allows natural gas operation
    • Available with explosion-proof I/P converter
  • The PositionMaster EDP300 is an electronically configurable positioner with communication capabilities designed for mounting to linear or rotary actuators. Advanced performance 4 to 20 mA with HART. The PositionMaster features a small and compact design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the positioner allow for considerable time savings as well as optimum control behavior. Because of its properties, the positioner is suited for even the most challenging operating conditions. General specifications:
    • Stainless steel housing
    • Non-contact position sensor
    • High air capacity
    • Operation with natural gas
    • Extended diagnostics

  • The TZIDC-200 is an electronically configurable positioner with communication capabilities, mounting to linear or rotary actuators. Standard performance, flameproof enclosure, with 4 to 20 mA HART. The TZIDC-200 features a small and compact design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the final control element yield considerable time savings and an optimal control behavior. General specifications:
    • Worldwide approvals for Explosion Proof and Intrinsic Safety
    • Vibration immunity up to 10 g
    • Autostroke function serves for perfect adaption to valve - fully automatic
    • HART protocol as standard for full access to smart functions, diagnostics, maintenance and fault detection; also designed for fieldbus communication
    • One positioner for linear and rotary actuators
  • The TZIDC-120 is an electronically configurable positioner with communication capabilities designed for mounting to linear or rotary actuators. Standard performance with FOUNDATION Fieldbus. The TZIDC-120 represents the digital, intelligent positioner for communication via FOUNDATION Fieldbus within the positioner family. Unmatched shock and vibration immunity of 10 g up to 80 Hz distinguishes the TZIDC-120 from other‘s and guarantee reliable operation in almost all areas under harshest environmental conditions. General specifications:
    • FOUNDATION Fieldbus communication
    • FF device registration: IT campaign no. IT 016800, ITK-Ver. 4
    • Easiest commissioning and operation on site due to local operation and auto adjustment
    • Worldwide Intrinsic Safety approvals
    • Robust design and flexible in use with linear and rotary actuators
  • The Model Series 74 Valve Positioners are universal positioners that provide versatility, dynamic performance, and high positioning accuracy. They use the piston ordiaphragm in a pneumatic actuator to position a valve to what is required by a control instrument and hold that position, regardless of the presence of forces that change valve position. As such, supply pressure variations have little or no effect on the positioner output, which eliminates the need for a supply pressure regulator.
    These valve positioners are two-stage, pilot-operated instruments. The pilot circuit activates dual-output boost-ers, which perform opposite actions (when one booster is supplying air, the other is exhausting air.) This “push-pull” action applies to a full differential (supply pressure to atmosphere) across the actuator to drive the valve to the position required by the control instrument signal.
    Model 74 Valve Positioners can also be used for single-acting service on a spring-loaded actuator. In this case, one of the pilot-booster connections is plugged. See below for rotary-type actuators.
