Fisherr 3024C Diaphragm Actuator

The 3024C actuator is a compact spring opposed

pneumatic diaphragm actuator incorporating a cast

yoke mounting and is suitable for general purpose

actuation of globe valves. It will position the valve plug

in response to varying controller or valve positioner

pneumatic output signals applied to the actuator

diaphragm. The 3024C actuator can be assembled as

either direct-acting or reverse-acting and provides

dependable and on-off or throttling operation of

automatic control valves.

Features

 Application Versatility–With eight different

configurations available, there is an actuator size to

meet your needs. Multi-spring combinations allow

for accurate selection of actuator thrust and valve

travel.

 Reversible Action–The simple design allows the

change of action from direct to reverse acting

without the requirement for extra parts. Change of

action can be easily made in the field.

 High Thrust Capability–The moulded diaphragm

and high strength casings allow for a maximum

casing pressure of 6 bar, enabling a high stem thrust

for a given size diaphragm.

 Positive Connections–Split block stem connection

provides a solid transfer of motion while allowing

easy mounting and no linkages that create lost

motion or inaccurate valve positioning.

temperature conditions from a minimum of -40_C

to a maximum of +82_C.

 Compact Design–The compact size minimizes

weight and space needed.

Product Bulletin 3024C Actuator 61.1:3024C March 2012 D103051X012 Direct Action With the direct action mode on the 3024C actuator, applying air pressure to the upper side of the diaphragm forces the actuator stem downward while, at the same time, compressing the springs on the underside of the diaphragm. Refer to figure 1. When this pressure is reduced, the opposing spring force moves the actuator stem upwards.
