Section 3: Installation
NOTE:
Mounting hardware is usually located on the shipping pallet/crate or inside panel cover of unit.
Gas/Hydraulic tanks must remain generally vertical, regardless of valve and valve stem orientation.
Lifting eyes are to be used in combination, with a 3 leg sling with one shortening hook, to lift the
operator only.
3.1 Field Mounting
1. Determine actuator orientation in relation to the pipeline and valve stem.
2. Place operator and valve in the same position (both open or both closed). Damage to
valve and/or operator can be caused if operator tries to open or close a valve against valve
internal stops. Operator position can be conrmed safely by operation with handpump.
3. Check mounting surfaces, valve stem, operator bore and orientation for any dimensional
discrepancy, dirt, rust, etc.
4. It is recommended that the stem key be set in place at this point before actuator is installed
on the valve stem.
5. Set operator in position on the valve. Keep hooks and chains clear of tubing and accessories.
6. Install mounting bolts to fasten operator to valve. Align operator to valve while bolts are
slightly loose, then tighten mounting bolts evenly and thoroughly to industry standard for
the grade and size of bolt.
7. If necessary, temporarily remove yoke cover and install key using tapped hole and eyebolt.
