  • Page 1: Table Of Contents

    This instruction manual includes installation, adjustment, operation, maintenance, and parts information for the Fisher 1051 and 1052 Size 33 diaphragm rotary actuators (figure 1). Mounting adaptations F, G, H, and J are included in this manual. Instructions for the control valve, positioner, manual actuator, and other accessories are included in separate manuals.

  • Page 2: Description

    5. NBR (nitrile) O‐rings are used in the optional top‐mounted handwheel and in the optional up travel stop assembly. 6. For higher temperature ratings, contact your Emerson sales office. 7. This maximum casing pressure is not to be used for normal operating pressure. Its purpose is to allow for typical regulator supply settings and/or relief valve tolerances.

  • Page 3: Specifications

    Instruction Manual 1051 and 1052 Size 33 Actuators D101322X012 June 2017 The 1052 uses an adjustable spring seat to control spring compression. It may be used for on‐off service without a positioner, or it may be used for throttling service with or without a positioner, depending on service conditions. A top‐mounted handwheel may be mounted for infrequent service as a manual override.

    Instruction Manual 1051 and 1052 Size 33 Actuators D101322X012 June 2017 CAUTION To avoid parts damage, do not use an operating pressure that exceeds the Maximum Diaphragm Casing Pressure (table 1) or produces a torque greater than the Maximum Allowable Valve Shaft Torque (see Catalog 14). Use pressure‐limiting or pressure‐relieving devices to prevent the diaphragm casing pressure from exceeding its limit.
  • Page 6 Make sure the actuator rod is perpendicular to the valve shaft. Refer to the valve instruction manual for specific end play considerations. Figure 3.Travel Stops and Switch Positions on the Fisher 1051 and 1052 Size 33 Actuator HOUSING COVER ASSEMBLY (KEY 33)

Stroking Range Key numbers referred to in this procedure are shown in figure 10 unless otherwise specified. If, under operating conditions, the desired stroking range cannot be achieved with the casing pressure used, it may be possible to shift the stroking range by making a spring adjustment to change the initial spring compression.
