Fisher 656 Direct-Acting Diaphragm Actuator
Fisher 656 diaphragm actuators provide small to medium thrust output for bracket-mounted applications. Fisher 656 diaphragm such applications include operation of Butterfly valves and built-in turbine valves, louvers, dampers, and other similar equipment.
- Maximum thrusts of up to 5.3 kN (1,200 lbf) can be produced, depending on construction.
- Depending on size, strokes of up to 105 mm (4 1/8 in) are available.
- Four tapped holes in the actuator base permit either bracket or plate mounting.
