Introduction

Scope of Manual

This instruction manual includes installation, maintenance, and parts information for the Fisher 785C piston actuator.

Refer to separate instruction manuals for information regarding other equipment and accessories used with these

actuators.

Do not install, operate, or maintain 785C actuators without being fully trained and qualified in valve, actuator, and

accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to

carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you

have any questions about these instructions, contact your Emerson sales office before proceeding.

Description

The 785C products line encompasses medium to large spring-return single-acting and double-acting piston actuators

that provide accurate, high thrust output for short to long travel applications. These actuators are designed for use

with a variety of medium to large Fisher sliding-stem control valves including.

The single-acting actuators feature an internal bias spring that forces the actuator piston rod to extend or retract upon

a loss of supply pressure, thereby ensuring a fail-closed or fail-open mode of operation. This effectively eliminates the

need for a trip valve and volume tank in most constructions.

1. The pressure/temperature limits in this bulletin and any other applicable standard or code should not be exceeded.

2. Consult your Emerson sales office for longer travels or larger cylinder diameters. The Fisher 585C family of actuators can be used for smaller travels or cylinder diameters.

3 Standard temperature -20 to 100_C (-4 to 212_F) and -40 to 100_C (-40 to 212_F) are PED 2014/68/EU and 2006/42/EC compliant. The low ambient temperature option, -60 to 100_C (-76 to 212_F)

is not PED compliant. The high temperature option, if used in conjunction with ATEX, is limited to 135_C (275_F).

4. Full stainless steel constructions are available upon request.

5. Refer to the product nameplates to determine which certifications each actuator construction possesses

Principle of Operation

785C piston actuators utilize a pneumatically controlled piston that moves inside of a cylinder to generate thrust. A

seal contained on the circumference of the piston provides a seal between the top and bottom of the cylinder,

preventing supply pressure leakage.

785C single-acting spring-return piston actuators utilize a spring below the piston (outside the pressurized chamber)

that will drive the piston rod upon a loss of supply pressure. This fail action will result in forcing an attached control

valve to either fail-open or fail-closed.

From an equilibrium state, the actuator operates by reacting to a force unbalance that is created by increasing supply

pressure on one side of the piston and decreasing it on the other. This moves the piston up or down, and results in a

repositioning of the attached control valve. Travel can be adjusted using travel limits within a valve positioner, which

limit the travel range of the actuator. The optional manual override does not have the ability to act as a hard travel

stop.

An optional manual override (top mounted handwheel or side mounted handpump) is capable of extending or

retracting the actuator manually and can be engaged at any position from full open to full close. The top-mounted

handwheel utilizes an engagement lever that couples the handwheel and piston rod. The handpump has a hydraulic

cylinder attached to the piston rod. This enables the handpump to operate the actuator manually, unless the

handpump is set to bypass position.
