This guide provides installation instructions, safety warnings, and gear mechanism replacement steps for the Victaulic 707 series butterfly valve.
The document details the proper installation of the 707 series butterfly valve, including important safety warnings such as wearing protective eyewear, a hard hat, and foot protection, and depressurizing and draining the pipe system before work. It also lists the valve’s pressure rating (300 psi/2065 kPa), UL and FM certifications, EPDM valve‑seat material, and required pipe type (grooved IPS carbon‑steel).
Installation steps cover positioning the valve in the closed position, using at least one rigid Victaulic joint, wiring the two DPDT monitoring switches, and the procedure for removing and reinstalling the gear operation mechanism with correct orientation and fasteners. The guide also provides wiring diagrams and color codes for the switches and grounding. This manual is written in Chinese.
