Use the tool specified for the valve assembly
Manufacturer service tools reduce damage to drive caps, spacer stacks, bypass caps, and other plastic valve parts. Confirm the tool's OEM number and the exact valve family. A tool listed for Clack WS1 service should not be assumed to fit an unrelated valve.
Tools do not replace the manufacturer procedure. Bypass and depressurize the equipment, disconnect power, and follow the documented disassembly and reassembly sequence.
