Questions buyers ask
What pressure, flow and temperature is it rated for?
The listing does not provide pressure class, flow coefficient (Cv), or temperature ratings for this unit. Fisher Type 657 valves are available in ANSI Class 150 through 600 configurations with varying trim options, but you'll need to ask the seller for the nameplate data or body markings that specify this unit's pressure rating, trim type, and material temperature limits.
What should I inspect before putting it into service?
The listing states this unit must be re-certified before use. At minimum, inspect the seat and plug for erosion or scoring, verify stem packing integrity and travel limits, bench-test the actuator for proper stroking and spring range, and confirm the positioner (if equipped) calibrates correctly. Pressure test the body per the rated class and verify all trim components meet your process requirements before installing.
