Pneumatic Actuator Handwheel with ISO5211 Square Bottom Connection

Product Feature

The manual overrides are “safety” features for when power is lost and the solenoid needs to be operated. 2 position valves with manual overrides, when activated, shift the valve to its energized position. Some 3 position valves come standard with a one-direction, push-pin manual override. When the manual override is pushed, the spool shifts following the logic of energizing S2. Manual override options are intended for emergency use only and are not intended for continuous operation.

Specifications

Declutchable manual overrides are used with pneumatic, hydraulic and back-drivable electric actuators. These products are sandwich mounted as part of an automated valve package to provide manual operation of the automated valve if a loss of plant air supply, power gas, hydraulic fluid power, or electricity occurs.

Standard ISO 5211 mounting dimensions on top and bottom flanges or custom machined for mounting to actuator and valve

Device is transparent to valve operation when disengaged

Suitable for either double acting or spring return actuators

One-handed declutch mechanism

Declutchable override sandwich mounted between valve and actuator

The declutch mechanism is designed to mount between the valve and its primary driving mechanism. The declutch locks in both the engaged and disengaged positions.

We offer a locking device for the SD manual overrides to prevent engagement or disengagement

Technical Data

Application

Standard worm gears can be configured to fit almost any partial-turn or multi-turn valve (e.g., ball valves, butterfly valves, etc.). Worm gear operators create a mechanical advantage in torque, which reduces the amount of work and/or the number of turns required to cycle a valve.
