BT Series Hydraulic Actuators Overview

The BT Series will provide superior performance in low pressure hydraulic applications. Floating piston ensure low breakaway pressure and smooth operations. Brass piston rings and piston bands eliminate leakage and cylinder scoring. Steel racks and pinions provide the strength and resilience for minimum downtime. A broad offering of options and accessories provides unmatched flexibility in design and applications. These include cushions, stroke adjusters, flow controls and position sensors, as well as application matched shaft, mounting, porting and seal variations.

Material Variations

Standard BT series comes with tough epoxy coated marine paint for adverse situations. High resistance to sea environment and harsh weather conditions for long term usage.

Standard material of Carbon Steel Standard paint: 200 um Epoxy marine paint. (Limit switch can be fitted upon option request)

Stainless Steel BT 316 series is designed specifically for highly corrosive environments. Stainless steel 316 has the standard properties of being very resistant to corrosion, gases and other chemical media. Most suitable for submerged conditions. High tensile strength of 316 stainless steel properties.

Application Variations

Like most other actuator designs, our products also come with the following application possibilities. From double acting to single acting, from submerged to non-submerged.

    DOUBLE ACTING:
  •   Open / Close functions
    SINGLE ACTING:
  •   Spring to Open (Fail Open)
  •   Spring to Close (Fail Close)
    MODULATION:
  •   Modulate to Open / Modulate to Close
  •   Modulation with spring to close duringlost of Hydraulic force

    Feature:

    The Solenoid Valve Cabinet is installed in a safe and non-hazardous area and responsible for the control and activation of the solenoid valves.

    SVC consists of solenoid valves and throttle valves which are important to monitor actuator operation time, high-pressure filter-to be removed and quick connectors (optional) for an emergency operation.

    In case the valve position indication is of indirect type, flow switches and/or volumetric indicators are also installed in this cabinet.

    Model Available:

  • SVC12
  • SVC36
  • SVC60
  • SVC72
  • SVC 80
  • SVC 96
  • SVC120 and etc.
  • Available in IP44 Rating & IP56 rating (ATEX/IECEX)

    Feature:

    Processing Cabinet is the link between SCADA/HMI consoles to the actuator field equipment. SPC collects data from field equipment and converts them to signals comprehensible by computers. SPC performs an important role in bridge device differences. Our processing cabinets / local control cabinets available in various designs:

    • Hardwire / Relay Systems.
    • PLC Processor-based design with Hot / Cold Standby Systems.
    • Hazardous Area / Increased Safety Systems.

    Available in IP44 Rating & IP56 rating (ATEX/IECEX)
