    PZM is the most common diaphragm actuator for our globe type control valves, and it can be assembly Siemens smart positioner, ABB digital positioner, South Korea positioner etc.

    multi spring diaphragm actuator
    PZM-4/5/6/7/8 Multi-Spring Diaphragm Actuator

    The multi-spring membrane pneumatic actuators of P/R type are applied for control operation
    of control valves, and other positioning elements in industrial automatic systems. There are
    three following design options of the actuator:

    APPLICATION AREA

    • Direct action (air – advances the steam)
    • Reverse action (air – retracts the steam)
    • Direct action, handwheel
    • Reverse action, handwhee

    FEATURES

    1. Completely reversible action, option to change spring range w/o extra parts.
    2. Rigid structure of cast yoke.
    3. Wide range of the available forces.
    4. Linear relationship between rod displacement and control pressure as a result of using membranes with constant active area.
    5. Various ranges of spring pressures due to changeability of spring number and /or dislocation of distance fencers.
    6. Capability of the actuator to incorporate side-mounted handwheel, pneumatic or electro-pneumatic positioners, limit switches, air sets, three-way pneumatic solenoid valves, lockup valves, position transducers.
    7. High strength of diaphragms, springs and packings.
    8. Small size and weight.
