Fisher™ 1051 and 1052 Size 33 Diaphragm Rotary Actuators (new not used)

General Description

Fisher™ 1051 and 1052 Size 33 Rotary Diaphragm Actuators are designed for precise control of rotary valves, particularly suited to on-off and throttling service applications. Due to their robustness and reliability, they are widely used in industrial environments, including the petroleum, chemical and refinery sectors, where precision and durability are essential. Purchasing a used Fisher™ 1051 or 1052 is convenient because these actuators maintain excellent operating efficiency even after years of service.

Main Components and Structure

  • Actuator Body : Made of steel or cast iron with anti-corrosion coating, to withstand aggressive environments.
  • Diaphragm : Made of NBR (nitrile) or VMQ (silicone), depending on specific temperature requirements, with an operating range from -40°C to 149°C.
  • Compression Spring : Adjustable via a spring seat to adapt the compression to the needs of the system.
  • Lever and Bearings : Lever support via bearings for smooth rotation, which reduces wear over time.
  • Position Indicators : Graduated disc and pointer to visually monitor the valve position.
  • Limit Stops : Externally adjustable, to limit the rotation of the valve shaft to 60° or 90°.

Dimensions and Mechanical Specifications

  • Diaphragm Pressure : Standard range of 0 to 1.2 bar (0 to 18 psig), up to 3.8 bar (55 psig) for some configurations.
  • Maximum Valve Shaft Rotation : 90 degrees, adjustable up to 60 degrees with integral travel stops.
  • Valve Shaft Diameters Acceptable:
    • F and G: 12.7 mm (1/2 inch), 15.9 mm (5/8 inch), or 19.1 mm (3/4 inch).
    • H: 22.2 mm (7/8 inch) with double flat surfaces.
    • J: 9.5 mm (3/8 inch), 12.7 mm (1/2 inch), or 15.9 mm (5/8 inch).
  • Approximate Weight : Fisher 1052: 21 kg (46 lbs).

Procedure for Use

  1. Mounting : Install the actuator onto the valve using the appropriate mounting adapter (F, G, H or J).
  2. Connection to Pressure Source : Connect the actuator to the air pressure source via the standard internal 1/4 NPT connections or the 1/2 or 3/4 NPT options.
  3. Stop Adjustment : Set travel stops to limit rotation according to system needs.
  4. Movement Control : Check that the valve opens and closes correctly through the movements of the actuator.
  5. Positioner Calibration (if equipped) : Adjust the positioner to obtain precise control of the valve position.

Maintenance of the Used Actuator

  • Diaphragm Inspection : Periodically check the integrity of the diaphragm for signs of wear or damage.
  • Bearing Lubrication : Lubricate the lever bearings to maintain smooth rotation.
  • Spring Check : Check the compression of the springs to ensure correct movement.
  • Checking Connections : Regularly check pressure connections to avoid leaks.

Workable Materials

The Fisher™ 1052 Size 33 is ideal for controlling fluids such as gases, steam, water, oils and other chemicals compatible with actuator materials.

Advantages of Buying a Used Fisher™ 1052

  1. Proven Reliability : These actuators are designed to last over time, making them perfect for purchasing as used machinery.
  2. Cost Reduction : A used actuator can offer excellent performance at a fraction of the cost of a new one.
  3. Availability of Accessories : Accessories, such as positioners and magnetic switches, can be added to improve the functionality of the actuator.

Application Sectors

  • Chemical Industry : Regulation of valves to control flows of chemical substances.
  • Oil Plants and Refineries : Control of valves in high pressure and variable temperature environments.
  • Water Management : Used in wastewater and drinking water control systems.

Conclusion

Purchasing a used Fisher™ 1051 or 1052 Size 33 Rotary Diaphragm Actuator is a smart choice for many industries, thanks to the combination of reliability, low costs, and availability of parts and accessories. Regular maintenance and thorough inspection ensure that the actuator continues to perform optimally for many years.
