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 specific unit. Fisher Type 657 valves are typically available in ANSI Class 150 through 600 pressure ratings with varying trim configurations, but you'll need to ask the seller for the nameplate data or request photos of the valve body markings to determine the actual ratings. The serial number 14403652 may allow Fisher or the seller to pull original manufacturing specifications.
What should I inspect before putting it into service?
The listing states this unit must be re-certified before use to ensure proper calibration and safe operation. At minimum, inspect the seat and plug for erosion or damage, verify actuator spring condition and diaphragm integrity, check all packing and gaskets, confirm stem travel and linearity, perform seat leakage testing per applicable standards (IEC 60534-4 or FCI 70-2), and calibrate the positioner or I/P if installed. Given the unknown service history, also verify that body and trim materials are compatible with your intended process fluid and conditions.
