Related Model: Fisher 8532 — High Performance Butterfly Valve. Sizes 3"-24", Classes 150-600. Application: Isolation and throttling, tight shutoff.
Packing Leak (Fugitive Emissions): PTFE or graphite packing develops leak at stem. Causes fugitive emissions that violate EPA LDAR requirements. Common after 5+ years or in high-cycle applications.
Repair: Replace packing set. Fisher ENVIRO-SEAL packing system provides <100 ppm emissions. Can be done in-line with valve under pressure using live-loading. Lead time: 1-3 days.
Actuator Diaphragm Failure: Rubber diaphragm in Type 667/657 actuator develops cracks or tears from age, ozone, or chemical exposure. Valve loses fail-safe capability and may drift from setpoint.
