Questions buyers ask
What pressure, flow and temperature is it rated for?
This valve has a 150 ANSI pressure rating with a 1-inch body size. Flow capacity and temperature limits are not provided in the listing; you'll need to request the valve's Cv rating and the specific trim material configuration from the seller to determine flow and temperature ranges for your application.
What materials are the wetted parts?
The valve body is 316 SS construction. The listing does not specify trim material, seat material, or diaphragm composition, all of which contact process media and affect compatibility—request a complete materials list from the seller.
What should I inspect before putting it into service?
The seller recommends inspection and servicing before commissioning to ensure proper calibration and performance. At minimum, inspect the diaphragm for cracks or hardening, verify stem travel and packing integrity, bench-test the SVI-2 positioner calibration against input signal, check for seat leakage at shutoff, and confirm the air filter regulator supplies clean, dry instrument air at the correct pressure.
