Explore our range of Fisher actuators, meticulously engineered to provide precise control and reliability in your operations.

01

Fisher Spring and Diaphragm Actuator 667 and 657

The Fisher® spring and diaphragm actuators are designed to offer on-off or throttling control of sliding stem control valves. The 657 is a direct acting fail open actuator where air is applied to the upper diaphragm casing overcoming the spring action to force the valve stem and plug down to close the valve. With a loss or reduction of air supply, the spring then forces the diaphragm plate up, forcing the valve to open.

The 667 is a reverse acting fail closed actuator where air is applied to the lower diaphragm casing overcoming the spring action to force the valve stem and plug up to open the valve. With a loss or reduction of air supply, the spring then forces the diaphragm plate down, forcing the valve to close.

  • Standard operating ranges are 3-15PSIG and 6-30PSIG.
  • Sizes are 30, 34, 40, 45, 46, 50, 60, 70,76, 80, and 100. Size 76 is only offered in a 667.
  • Top mount and side mount handwheel options available
  • Travel stops are available to limit the amount of travel.

Fisher® 1051/1052 Spring Return Rotary Actuators

Fisher® 1051 and 1052 actuators are single acting spring rotary actuators for throttling or on/off control for rotary valves. 1051 models require a positioner, while the 1052 can operate without the need of a positioner due to its adjustable spring.

  • Single acting
  • Sizes are 40, 60, and 70 (1052 only)

03

Fisher® 1061

The Fisher® 1061 is a pneumatic piston type actuator to control splined rotary control valves. Can be controlled for on/off control with a two-position control system, or for throttling service with a double acting valve positioner.

  • Available sizes are: 30, 40, 60 68, 80, 100, and 130.
  • Minimum operating pressure is 20PSIG without a positioner and 5PSIG above actuator requirement with a positioner.
  • 90-degree travel without a travel stop. 60-degree travel with the use of an integrated travel stop.

04

Fisher® 480 Yokeless Piston Actuator

The Fisher® 480 yokeless piston actuator is designed to control ball valves, butterfly valves, louvers, and dampers with either on-off or throttling control.

  • Low profile compact design.
  • Minimum cylinder pressure of 35PSG and a maximum pressure of 100PSI.
  • Standard input range of 3-15psig or 6-30psig.
  • Available sizes are: 30, 40, and 60.

05

Fisher® 585C Double Acting Piston Actuator

The Fisher® 5851C piston actuator is a very strong double acting actuator that is designed for either on-off or throttling control for sliding stem control valves. For on-off control switching valves are required. For throttling control, the use of either a DVC6200 or 3600 series positioner is required. Fail-safe action is available with the use of Fisher® 377 trip valve and volume tank.

  • High thrust capability with the 558C size 130 offering up to 25,000lbs of force.
  • Available range of travel up to 8 inches.
  • Available sizes are: 50, 60, 68, 80, 100, and 130.
