Expert Repair & Failure Analysis

What Usually Goes Wrong

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.

Repair: Replace diaphragm and inspect actuator spring. Fisher diaphragm kits available for most sizes. Lead time: 1-2 weeks. Emergency: 2-3 days with expedited shipping.

Seat Leakage (Class IV to VI): Valve fails to achieve required shutoff class. Causes include seat damage, thermal distortion, or foreign material between plug and seat.

Repair: Lap plug and seat ring to restore sealing surfaces. If damage exceeds 0.005", replace trim. For Class VI (bubble-tight) shutoff, soft seat inserts may be required. Lead time: 2-4 weeks.

Repair Lead Time

Complete valve rebuild: 3-6 weeks — full teardown, all internals, hydro/seat test
