Questions buyers ask
What pressure, flow and temperature is it rated for?
The valve body is rated for 300 ANSI pressure class with a 6-30 PSI actuator action range. Flow capacity and temperature limits are not provided in the listing; you'll need to request the Cv value and material temperature range from the seller, or refer to Masoneilan's published data sheets for the 88U-25125 model with 1" body size.
What materials are the wetted parts?
The valve body is 316 stainless steel. Trim materials, diaphragm composition, seat material, and stem construction are not specified in the listing—request a full materials of construction list from the seller, particularly if you need compatibility verification for corrosive or high-purity service.
What should I inspect before putting it into service?
The listing recommends inspection and re-servicing prior to installation. At minimum, verify diaphragm integrity for cracks or deterioration, check trim for erosion or damage, confirm the SVI-2 positioner calibration and electrical connections (30V supply), test actuator stroking through full range, inspect all seals and gaskets, and pressure test per ANSI standards. Verify the air filter regulator element condition and confirm instrument air quality meets ISA 7.0.01 standards to prevent positioner contamination.
