  • Hytork Air Fail Safe Actuator - China

    price: contact company for price

    The Hytork Air Fail Safe Actuator is for larger valves with higher

    torque requirements, requiring reliable fail safe operation utilising a

    unique in-built air reservoir giving fail safe action without the torque

    losses inherent of spring designs.

    For torque requirement valves up to

    28500 inch.

    lbs (3220 Nm.

    ) The AFS (Air Fail Safe) actuator is designed

    to provide a high fail stroke torque in a double rack and pinion

    actuator that cannot be achieved using springs.

    All the safety and

    performance features of double rack and pinion actuators are maintained

    as is the Hytork XL reliability.

    The HYTORK AFS maintains the highest

    seen air supply pressure within the chamber modules, to be released upon

    control demand.

    This design also prevents closure 'creeping' when air

    supply pressures drop, which occurs with all spring return designs.

    Torque output is constant in the powered stroke with only a small drop

    off on the fail stoke.

    The available torques are proportional to the air

    supply pressure.

    Spring changes for various air supply pressures need

    not be made.

    The AFS operates as a double acting actuator in both

    directions until there is a loss of supply pressure.

    When this loss

    occurs, the compressed air stored in the chambers powers the actuator to

    close the valve.

    This makes the AFS Series suitable for use in ON/OFF

    and MODULATING CONTROL situations while still providing the fail safe

    requirement.

    The AFS is supplied already furnished with an installed,

    direct mount solenoid valve.

    The coil type is selected to suit your site

    requirements.

    This saves on site piping and ensures the assembly has

    been fully tested.

    At the same time, we still can offer the items as below:

    Hytork XL 'Commando' Valve Actuator
